    Kvalitetsprocesser för Lagring och Distribution av Livsmedel på Schenker Coldsped2005Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of the thesis is to make plans for how Schenker Coldsped should act to meet customer demands, in this case from Burger King, for the use of EFSIS standards (European Food Safety Inspection Service).

    EFSIS offers independent third party inspection services specially designed for food, beverage and related industries. The standard Schenker Coldsped aims to certify to is the

    EFSIS technical standard for the storage and distribution of foodstuffs. Coldsped is a part of Schenker Sverige AB. The company offers total solutions for transportation and storage of refrigerated and frozen products all over Europe. Coldsped has a total of 800 refrigerated vehicles and also offer storage of refrigerated and frozen products as well as product refinement such as preparation, thawing, sawing, packaging and labelling.

    To be allowed to handle foodstuffs, companies in Sweden are obligated to enact selfregulation applicable to their line of business. This supervision shall include a HACCPplan, which is a system for identifying, assessing and controlling risks of importance to food safety.

    By introducing the EFSIS technical standard for the storage and distribution of foodstuffs at Coldsped establishments, routines and knowledge will be documented. Consequently staff knowledge will be incorporated in the company’s ISO9001:2000 system, Isopeq, as well as being available in files in the corresponding department. A first step towards the implementation of EFSIS is the decision to incorporate the HACCP-plan into Isopeq, the company’s quality system.

    Advantages of working to the EFSIS technical standards are:

    •A safer handling of foodstuffs

    •More documented systems

    •A more effective organisation

    •A more effective and clear communication with new customers

    •Increased competitiveness My recommendation is to implement changes in line with my plan. This calls for:

    • Investment in existing plants

    •Personnel resources for the process

    •Planning the implementation in detail by coordinating resources

    •Join the CIES (an independent network for companies handling food) for benchmarking

    Quality of Life of Elderly People in Iran: With Sevice Design Approach2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In the aging world of today, more attentions are grabbed towards studies on elderly. New facilities and technologies are emerged to serve to the elderly, maketheir life easier, better and more useful. Having participated in a study on thequality of life of the elderly in Europe, it was aimed to run a similar project toresearch the quality of life of the elderly in a Non-EU country. This was donethrough the research questions “What is the quality of life for them?” and “Howa designer, focused on service design, can improve their quality of life?”The knowledge for the study was obtained from fields Quality of Life of ElderlyPeople, Service Design, Service Design Process, and Qualitative Research. As thekey country for this study, Iran was chosen. Study on the target group in thiscountry was done through Cultural Probes and in analyzing the probes, Processfor Empathy in Design was used. To visualize the results of the target group study,Affinity Diagrams and Personas were drawn.The result was designing a service for the target group, which is presented byConcept Scenario, Storyboards, System Maps and Blueprints. In this concept,called “Virtual Family”, the personas are encouraged to be members of a networkwhich is supported by an organization/community in terms of health, social life,leisure activities and educational programs. This network is forming a virtualfamily regarding the traditional values and ethics which are important for thisage group. Additionally it supports them with entertainment and educationalprograms. Later on, the service concept was evaluated by a number of people inthe same age and social group of the target group. Evaluators found the conceptan excellent complement for mentioned target group who are on the verge oflosing their family and social structure, but the organizational system of the contextcountry should be studied to know if it is planning is practical in that context.

    Staten som förebild?: om planer, insatser och utfall i 17 myndigheters arbete med etnisk mångfald2004Report (Other academic)
    Abstract [en]

    The “State as a Role Model” report (Staten som förebild?) deals with the observance of the federal politicians’ regulatory instructions and ethnic diversity work in government authorities. The general idea is that the integration policy be taken seriously, both through giving concrete substance to the objective, of the state serving as a model, when it comes to ethnic diversity, and through examining adherence to this objective. The report focuses on planning, initiatives and outcomes. Working on the basis of the regulations set out by Swedish parliament and Government, the action plans of 17 federal authorities are examines with respect to ethnic diversity, the 17 authorities are asked about their work with diversity, and the outcome in their personnel numbers are mapped. The relationships between planning, initiatives and outcomes are considered, as are the regulatory instructions.

    Of the 17 authorities selected, 15 have drawn up action plans for promoting ethnic diversity. Generally speaking, most of these programs are weak from a content perspective, and the authorities’ diversity work is in need of holistic thinking. Methods for incorporating the integration policy into current day-to-day activities need to be developed.

    One overall impression gained from the interviews with the authorities is that internal work to increase and better utilize the diversity found in Swedish society is perceived as fairly new, and as yet both given relatively little reflection and rather shaky. All of the authorities interviewed need to further develop their diversity work, some more than others.

    When it comes to the outcome in personnel numbers, the percentage of foreign-born individuals working at the 17 authorities is in general considerably lower than the corresponding figure for foreign-born workers otherwise employed in the nation. The fact that foreign-born individuals are generally under-represented in federal administration is reflected in their also being under-represented in different occupations at the 17 authorities, especially with respect to management positions.

    One important observation is that, at most of the authorities surveyed in the study, there was a decline in the total number of employees between the years of 1997 and 2001, although this has not affected foreign-born employees, as is otherwise often the case. The need to hire new people at the 17 authorities during this period, as a whole, has been small. This means that any substantial changes in the composition of personnel through new recruitment have not been possible during the initial years of the integration policy.

    When focus is directed to the local and regional levels, and to the more concrete day-to-day work of the authorities, it becomes clear that an authority’s diversity work is characterized by the nature of its activities. Indepth study on the local and regional levels also shows the importance of organizing the work, as well as the importance of diversity for externally-oriented activities, and that diversity can be perceived as somewhat of a sensitive, new or unfamiliar issue. The closer analyses also show that organizations can follow independent strategies in relation to their plans for ethnic diversity.

    Even if no strong connections can be demonstrated between planning, initiatives and outcomes in the analysis in this report, the Swedish Integration Board feels it is too early to rule out the federal stipulation that authorities use special action plans in their work to promote ethnic diversity. One must remember that the integration policy is a new policy that involves long-range development processes, not all of which are subject to immediate impact. Before the policy is abandoned, the directives on diversity should be implemented in full. One way to make the policy more clear may be to write more specific demands into the directives and budget appropriations to the authorities.

    Festiketten: Developement of an E-commerce Web Application for custom designed bottle labels2015Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [en]

    The report examines how an online store for custom designed bottle labels can be developed as a web application, and aims to contribute to the existing research on web design. The development is based on the vision” to provide custom labels through an online store which puts the icing on the cake for your special occasion”, with persons in the age 25-40 who are planning a wedding or another large event as target group. The technical methods which can be used are presented in the report and what impact they had on the competitive aspects of the online store. Design strategies for building user trust are discussed among others, as essential parts of e-commerce according to the presented theory. Furthermore, the report presents more concrete technical methods for increasing the competitiveness such as faster loading times and search engine optimization. Especially loading times plays a central role for the success of a web application according to the related theory. The methods which has been used and why, considering the collected theory, are presented in the report. The conclusions of the report states that an online store successfully can be developed using an agile methodology such as Scrum and that it can take benefits from being implemented as a single page application. Developing a design tool for custom bottle labels proved to be a difficult balancing act between customization and simplicity.

    Lärstilar: Om deras betydelse för lärares planering och organisation av matematikundervisningen2015Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Gymnasieskolor har fått kritik av Skolinspektionen (2010) för avsaknad av individanpassning av matematikundervisningen och det saknas tid för elever till reflektion över olika matematikfenomen och inlärningssätt.

    Det här Syftet med detta examensarbete är att sammanställa aktuell forskningslitteratur som behandlar elevers individuella inlärningsstilar (här kallad lärstilar) för att öka kunskapen hos lärare och blivande lärare huruvida lärstilar har betydelse för elevers inlärning och lärastilars betydelse för organisation av matematikundervisningen. Följande frågeställningar analyseras utifrån litteraturen: Hur kan olika lärstilar klassificeras? Vilka tester används för att fastställa olika lärstilar? På vilket sätt kan olikhet i lärstilar få konsekvenser för hur lärare bör planera och organisera matematikundervisningen? Mina resultat pekar på att det finns en mängd av konkurreande lärstilsteorier men visar trots det på att det går att hitta gemensamma nämnare för klassificering av de olika teoriernas lärstilar. De tester som har identifierats är LSI (Kolb´s lärstilsteori) och PEPS (Dunn´s lärstilsteori), vilkas validitet kritiseras och kontinuerliga omarbetningar av testerna utförs. Lästilsteorierna baserar sig på att elever lär sig bäst genom undervisning anpassad efter elevernas olika lärstilar, vilket betyder att läraren behöver ta hänsyn till anpassning i form av olika faktorer såsom miljöfaktorer, emotionella faktorer, sociala faktorer osv. En klass består oftast av elever med olika lärstilar och en konsekvens är att läraren behöver använda olika undervisningsmetoder och matematikundervisningen kan i och med det bli mer omväxlande och därigenom öka lusten för matematikstudier. Min studie pekar också på att lärstilsteorierna ger matematiklärare möjlighet att reflektera över individanpassning av matematikundervisningen.

    Time and Activity Analysis of Doctors and Nurses Work Assignments2015Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With people’s increased life span, the demand for health care services has increased, while there is a lack of health care professionals. By increasing the health care professionals’ value-adding work assignments for patient care, they will be used more efficiently and be able to meet the demand of the health care services.

    Based on observations and time studies carried out at Vrinnevisjukhusets health care facility for stroke and rehabilitation of stroke, this thesis has provided suggestions for areas of improvement which could increase the amount of doctors’ and nurses’ value-adding work assignments. Based on the result time studies at the health care facility, a time distribution of the doctors’ and nurses’ work assignments was also established and showed that they spent their most time on administrative work (48 % for doctors and 26 % for nurses), communication (15 % for doctors and 24 % for nurses) and time with patient (15 % for doctors and 20 % for nurses).

    Based on the observations and the result of time distribution, the doctors and nurses main areas of improvement was the lack of guidelines for implementation of journal notes which made their administrative work assignments inefficient, as well as the lack of system for the stock levels of medicines, which hindered the nurses’ medication management. To address these problems the health care facility and the entire medical clinic that the facility is part of, should determine guidelines on how the journal notes should be conducted for avoidance of duplications and to also facilitate the search of information. The medical clinic should also invest in a new storage system which updates the stock levels of medicines automatically, and also makes it possible to see how much of each medicine is available in each facility and storage. The arrangement of the facilities storage is also an area that could be improved by implementing the Leans’ 5S, which would improve the doctors’ and nurses’ time distribution and increase the value-adding work assignments. By also planning and clarify when a reporting is ongoing, as well as relocate or invest in more printers and telemetry computers, the facilities doctors’ and nurses’ time distribution will be improved and also increase the amount of work assignments that is value-adding.

    Socioeconomic Impacts of Transitioning to Collaborative Port Operations - A case study of the Port of Gothenburg2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to derive a method for estimation of costs and benefits of implementing Port Collaborative Decision Making (Port CDM), and to apply this method to the Port of Gothenburg. By using the Port of Gothenburg as a case study, conclusions can be drawn regarding the economic viability of Port CDM in one of Scandinavia‟s largest ports. This study considers two major sources of benefits that are hypothesized to result from transitioning to collaborative port operations: improved possibilities for speed optimization prior to arrival in port due to increased predictability in estimated berthing times, and shortened service times due to increased possibility for planning and resource optimization by port service providers.The estimation of impacts is based on one month‟s traffic data in the Port of Gothenburg. Predictability of estimations is analyzed to determine the benefit potential of Port CDM. The estimated cost savings for cargo vessels can be divided into 5 categories: bunker, emission, time, manning and capital cost savings. The costs of implementing and maintaining Port CDM are estimated with values from relevant previous research.The results of this study indicate that the implementation of Port CDM in the Port of Gothenburg is a profitable investment, for the shipping industry and for society as a whole. The estimated annual net benefit is 27.3 million euros. A sensitivity analysis using alternative unit valuations for emissions, as well as low and high estimations of the effectiveness of Port CDM, indicates that the economic viability of the project is robust under all assumptions considered.

    A Process Perspective of Corporate Rebranding in SMEs: A multiple case study of Restaurants and Bars in Osteragotland2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: In recent years, the subject of corporate rebranding has been receiving increasing attention as companies strive to develop new differentiated identities in the minds of their stakeholders. Several studies have been conducted on this subject, however, these studies have been biased towards large companies. Despite small and medium-sized enterprises (SMEs) being the most common type of businesses, most of the research on corporate rebranding has been focused on large corporations. Owing to the limited research studies on corporate rebranding in SMEs, this study seeks to shed more light on this subject by studying how the corporate rebranding process occurs in SMEs. By doing so, this study seeks to fill part of the research gap identified and contribute to the body of knowledge about corporate rebranding process in SMEs.

    Methodology: The empirical approach involves a multiple case study of four SME companies from the restaurant and bar sector. The data was collected through semi-structured interviews with key informants from each company, through observations and also the use of secondary sources.

    Results:The findings showed that the corporate rebranding process in SMEs involves few actors and is mostly owner- driven with the owner being at the centre of most of the activities and decision making. Furthermore, the findings show that the reasons for corporate rebranding in SMEs are change in ownership structure, bad reputation and change in market preferences. Based on the findings, we propose a corporate rebranding framework for SMEs that consists of the stages Assurance, Analysis, planning, Realisation and Evaluation.

    Route planning for delivery trucks at Ekoparti AB2015Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Ekoparti AB är ett grossistföretag som idag har cirka 480 kunder runt om i mellersta Sverige. Idag omsätter Ekoparti AB 165 miljoner kronor per år och har resurser som uppgår till 30 heltidsanställda personer, samt att man äger ett lager på 3000 kvadratmeter, varav 500 av dem är frys. Företaget har även sex stora lastbilar och två skåpbilar. På senaste tid har Ekoparti AB insett att det finns brister i distributionen mot kund. De har tagit fram två punkter som de anser vara bristerna i företagets logistiksystem. Dessa är att kundernas ordermönster behöver förändras, samt att vissa kunder avviker från leveransrutterna som går från företagets lager, samtidigt som de beställer för lite. Utifrån dessa punkter har de tagit fram ett nytt förslag för hur distributionen mot kund borde ske i företaget. Projektets uppgift blev då att undersöka de nuvarande leveranserna samt det nya förslaget och jämföra dessa två för att se vilket som blir mest kostnadseffektivt och varför. För att lösa problemet valde vi att använda programmet ArcMap som en bas för analysen av rutterna. Med hjälp av programmet kunde kostnader för att köra de olika rutterna i nuläget och i förslaget tas fram. Resultatet av analysen blir att det nya förslaget är mer kostnadseffektivt än hur distributionen hanteras i nuläget, med en minskning av kostnaderna med 614 950 kronor per år. För framtagning av resultatet används två huvudsakliga kostnadsfaktorer, vilket är tidskostnader och distanskostnader. När vi granskade resultatet var det tydligt att den variabel som har störst påverkan på kostnaderna är tidskostnaderna. Med tidskostnader menas lönekostnader för chauffören och hans medpassagerare. Dessutom tar vi även i rapporten upp att förändringen inte enbart påverkar transporterna, utan förändringarna skulle även kunna påverka andra delar av logistiksystemet, vilket i sin tur kan påverka andra delar av företaget. Slutsatsen av projektet är att det nya förslaget för rutter är mer kostnadseffektivt för Ekoparti AB än de nuvarande rutterna. I och med att tidskostnaderna utgör majoriteten av totalkostnaderna bör man för att minska totalkostnaderna ta fram lösningar som minskar den spenderade tiden vid distributionen till kunderna. Dessutom får man inte bortse från helhetsperspektivet då transportförändringar inte bara påverkar transporterna utan även resterande delar av företaget. Detta för att undvika oönskade negativa effekter i andra delar av verksamheten när man genomför en förändring

    Exploring the role of multi-functional solutions when planning for climate change: A case study of stormwater management in a Swedish city2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Managing stormwater sustainably in the face of extreme weather events has increasingly been recognized as a strategy for climate adaptation in the urban planning context. Sustainable stormwater management intends to reduce urban vulnerability while ensuring the overall sustainability and robustness of future cities. To add to the emerging research field of green infrastructure, the objective of the study is to explore the role of multi-functional solutions as a climate change response in urban planning and development. This study has been driven by an inductive research process and draws on empirical data collection through workshops and interviews with City Hall officials in Motala City. The study concludes that despite the lack of preventative planning to anticipate climate change, city renewal and urban development of Motala City presented a window of opportunity to implement potential multi-functional stormwater solutions in the urban environment through urban planning. Further, increased focus on internal and external collaboration through the process of envisioning the future of the city have enabled new forms of governance and facilitated arenas for public acceptance and an integrative planning-approach. Lastly, discourses on attractiveness enabled greenery to be viewed from a social, economic and environmental perspective, supporting multi-functional stormwater solutions as a strategy for climate adaptation and urban sustainability.

    Planering och didaktiska övervägande kring problemlösning i matematikundervisningen - en intervjustudie med lärare från gymnasiesärskolan2015Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie har behandlat problemlösning i gymnasiesärskolans matematikundervisning. Syftet har varit att undersöka vilka didaktiska övervägande sex gymnasiesärskolelärare i matematik gör i sin undervisning kring problemlösning och hur de planerar och reflekterar kring detta.

    En induktiv metod har använts eftersom ingen särskild teori ligger i botten. Metoden är kvalitativ och data har samlats in från semistrukturerade intervjuer som har behandlats med tematisk analys, innehållsanalys, där hela materialet använts.

    Ur materialet kommer gymnasiesärskolelärarnas didaktiska överväganden fram kring hur, var, vad och varför problemlösning görs. De lyfter även fram sin planering och reflektion. Den innefattar framtagning av eget material, både praktiskt och textmaterial, som görs för att anpassa både efter elevernas kognitionsnivå, centralt innehåll i kurs- och ämnesplaner och koppling till samhället. Lärarna lyfter fram problemlösningen som viktig och att den ska beröra något vardagsnära. Eleven ska därigenom ges möjlighet att generalisera och självständigare kunna hantera problem som uppkommer i vardags- och yrkesliv. Problemlösning är viktig för elevens lärande både vad gäller kognitiva aspekter som begreppsförståelse och förståelse för matematiken i sitt sammanhang. Även affektiva aspekter lyfts fram såsom att problemlösning kan stärka elevens självförtroende och öka självständigheten.

    Timeefficiency of constructionwork in a developing country2015Independent thesis Basic level (university diploma), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    To work time efficient, structured and to not waste time are important factors at a construction work. Time is money and the more time a job takes the more money it costs. In theory, there are several factors that affect the efficiency at a construction site. Some of these factors are structural and schedules, work preparation, planning, method improvement and to identify targets. Most of these factors are used in construction work in Sweden, but the construction is not as developed in a developing country and they often work day by day. A country that has problems with efficiency in the workplace is the poor country Philippines in Asia.

    During a volunteer work trip to the Philippines was the deficiencies and timing problems during construction observed. Volunteer work took place in a small village called Los Amigos outside the town of Davao. The work was to build and renovate homes and the area around the buildings for wheelchair people who can’t afford their own homes. Besides the volunteer work was a construction site that was observed during the trip. The construction site is made up of a basketball court.

    This study aims to observe the construction work in the Philippines to identify problems with building work and efficiency in the workplace. Through observations and an interview with a supervisor in the village of Los Amigos have the different time problems been reflected and discussed. Based on the theoretical frameworks and taking into account the culture of the country have improvement proposals been worked out.

    The report ends with two sections that describe how to work more time-efficient, structured and avoid time losses. One section deals with the construction work on volunteer work and the other for a work on the basketball court built in the same area. The workplaces are of completely different character and various improvement proposals have thus been drawn up.

    Increased efficiency of experience feedback between production and budget2015Independent thesis Basic level (university diploma), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The construction industry has during many years been regarded as a problematic industry. As a result of this the government 2002 set up a commission with the aim to discourage negative trends in the industry. The commission acknowledged the problem with work activities being reconstructed between projects. As a result of this the experience being acquired in one project did not come to use in the next. In the construction industry it is a well-known fact that around 10% of the cost of production can be categorized as error and controls. The most of the errors that occur can be eliminated with better planning. A tool to be used is experience feedback which purpose is to use the knowledge gained from earlier projects to predict future projects. The purpose of this study is to examine and highlight problems that can occur when experience shall be fed back between production and budget with the aim to present suggested improvements. The study is divided into three questions where the first question investigates which data is relevant from production in order to make well motivated production budgets. The second question explores, in a collaboration with SM Entreprenad AB, which conditions there are today regarding experience feedback between production and budget. The third and final question reviews improvements to be made. The first question is being answered with literature as reference while the second and third has its focus on interviews. The results of the study shows that a budget is constructed with earlier projects as reference where data mainly regarding time, used amount of material as well as used material/equipment are the central variables that need to be fed back to budget. The situation at SM Entreprenad today is that they more or less are not feeding back any data from production with the aim to make well motived budgets. The study shows regarding improvements to be made that there are a lot of data to be used, but they lack routines in order to use this data.

    Charging Cost Optimization of Plug-in Hybrid Electric Vehicles2015Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The future success of chargeable vehicles will, among other factors, depend on their charging costs and their ability to charge with minimal disturbances to the national, local and household electrical grid. To be able to minimize costs and schedule charging sessions, there has to be knowledge of how the charging power varies with time. This is called charging profile. A number of charging profiles for a Volvo V60 plug‑in hybrid electric vehicle have been recorded. For charging currents above 10 A they prove to be more complex than are assumed in most current research papers.

     

    The charging profiles are used together with historical electricity prices to calculate charging costs for 2013 and 2014. Charging is assumed to take place during the night, between 18:00 and 07:00, with the battery being totally depleted at 18:00. By using a timer to have the charging start at 01:00, instead of immediately at 18:00, annual charging costs are reduced by approximately 7 to 8%. By using dynamic programming to optimize the charging sessions, annual charging costs are reduced by approximately 10 to 11%. An interesting issue regarding dynamic programming was identified, namely when using a limited set of predetermined discrete control signals, interpolation returns unrealizable cost-to-go values. This occurs specifically for instances crossing the zero cost-to-go area boundary.

     

    It is concluded that the mentioned savings are realizable, via implementing timers or optimization algorithms into consumer charging stations. Finally, by using these decentralized charging planning tools and seen from a power usage perspective, at least 30% of the Swedish vehicle fleet could be chargeable and powered by the electrical grid.

    Abstract [en]

    Parallelization is the answer to the ever-growing demands of computing power by taking advantage of multi-core processor technology and modern many-core graphics compute units. Multi-core CPUs and many-core GPUs have the potential to substantially reduce the execution time of a program but it is often a challenging task to ensure that all available hardware is utilized. OpenMP and OpenCL are two parallel programming frameworks that have been developed to allow programmers to focus on high-level parallelism rather than dealing with low-level thread creation and management. This thesis applies these frameworks to the area of computed tomography by parallelizing the image reconstruction algorithm DIRA and the photon transport simulation toolkit CTmod. DIRA is a model-based iterative reconstruction algorithm in dual-energy computed tomography, which has the potential to improve the accuracy of dose planning in radiation therapy. CTmod is a toolkit for simulating primary and scatter projections in computed tomography to optimize scanner design and image reconstruction algorithms. The results presented in this thesis show that parallelization combined with computational optimization substantially decreased execution times of these codes. For DIRA the execution time was reduced from two minutes to just eight seconds when using four iterations and a 16-core CPU so a speedup of 15 was achieved. CTmod produced similar results with a speedup of 14 when using a 16-core CPU. The results also showed that for these particular problems GPU computing was not the best solution.

    Motion Planning and Stabilization for a Reversing Truck and Trailer System2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis work contains a stabilization and a motion planning strategy for a truck and trailer system. A dynamical model for a general 2-trailer with two rigid free joints and a kingpin hitching has been derived based on previous work. The model holds under the assumption of rolling without slipping of the wheels and has been used for control design and as a steering function in a probabilistic motion planning algorithm.

    A gain scheduled Linear Quadratic (LQ) controller with a Pure pursuit path following algorithm has been designed to stabilize the system around a given reference path. The LQ controller is only used in backward motion and the Pure pursuit controller is split into two parts which are chosen depending on the direction of motion.

    A motion planning algorithm called Closed-Loop Rapidly-exploring Random Tree (CL-RRT) has then been used to plan suitable reference paths for the system from an initial state configuration to a desired goal configuration with obstacle-imposed constraints. The motion planning algorithm solves a non-convex optimal control problem by randomly exploring the input space to the closed-loop system by performing forward simulations of the closed-loop system.

    Evaluations of performance is partly done in simulations and partly on a Lego platform consisting of a small-scale system. The controllers have been used on the Lego platform with successful results. When the reference path is chosen as a smooth function the closed-loop system is able to follow the desired path in forward and backward motion with a small control error.

    In the work, it is shown how the CL-RRT algorithm is able to plan non-trivial maneuvers in simulations by combining forward and backward motion. Beyond simulations, the algorithm has also been used for planning in open-loop for the Lego platform.

    Statistisk kvalitetsvärdering för optimering av processteg i aluminiumanodisering: Utvärdera avverkning på aluminiumdetaljer i avverkningsbad2015Independent thesis Basic level (professional degree), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    The intention with this thesis was to evaluate how much pickling that have been achieved on aluminium details in the pickling bath before the anodization in an anodization process. As there were no earlier studies to use around pickling before anodization, statistical experimental design was chosen as planning tool. Statistical experimental design was used to plan the experiments in an organized way and to evaluate how the pickling process works together with the main effects and the interaction effects. Detailed scientific studies were performed on how aluminium is prepared and how the anodization process works. The studies were performed in reference books. Three different methods were designed. The first method, method 1, was based on a fractional factorial design with four design variables, temperature, sodium hydroxide and aluminium concentrations and the time the details was submerged into the pickling bath. The aluminium details was made from a square profile pipe. There was nine experiments performed in method 1. The measurements on the pickling was performed in two ways, first with a dial indicator where the pickling was compared with a reference surface before and after, and another method also performed with a dial indicator, where the measurements was performed over the edge between the pickled surface and the reference surface. A statistical control calculation was done on the surface smoothness of the square profile pipes. The control showed that the standard deviation was 11 µm. Method 2 was based on a complete factorial design where the design variables was temperature and the time the details was submerged into the pickling bath. All aluminium details were homogenous. There were seven experiments performed in method 2. The measurements on the pickling was performed in two ways, first with a dial indicator where the pickling was compared with a reference surface before and after, and another method also performed with a dial indicator, where the measurements was performed over the edge between the pickled surface and the reference surface. A statistical control calculation was done on the surface smoothness of the homogenous details. The control showed that the standard deviation was 14 µm. Method 3 was designed in a different way than method 1 and 2. In method 3 one experiment was performed and the design variable which was changed was the time when the details was submerged into the pickling bath. The aluminium details had the form of homogenous cubes. The measurements on the pickling was performed by measuring the weight of the details on an analytical scale before and after the pickling, and then calculate the pickling in µm in two different ways. The first way was to use the atomic radius of aluminium and the second way was to use the size of the unit cell of aluminium. The two first methods gave very different results than the third method. The result for method 1 showed very random values with great dispersion which resulted in a non-detectable pickling. The result for method 2 was very similar to the result from method 1, very random values with great dispersion and no pickling was detectable with any confidence. The result from method 3 gave a theoretical calculated result for the pickling, when the aluminium details was submerged in the pickling bath for 1 minute, and based on the atomic radius of aluminium, of 1,52 µm and with the same conditions but using the unit cell of aluminium showed a pickling of 1,62 µm. When the aluminium details were submerged in the pickling bath for 3 minutes, the theoretical calculation with the atomic radius of aluminium gave that the pickling was 4,51 µm and with the same conditions but using the unit cell of aluminium showed a pickling of 4,79 µm.

    An in depth analysis of the Preferential Bidding System for SAS Crew Planning2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Crew planning is a complex optimization problem that usually is divided into two separate parts, pairing and rostering. In the rostering process crewmembers are assigned a personal roster, a schedule, for the next coming time period. In order for the crew to have an influence on their roster, SAS have implemented a Preferential Bidding System (PBS) where the crew has the ability to express their wishes regarding their roster, formulated as bids. Generally there is an outspoken dissatisfaction among the crew about PBS and how it works and therefore the questions were raised of how the system could be more transparent and how the bid fulfillment could be communicated both internally and externally. The performed analysis was made with regard to bidding pattern and bid fulfillment and was both quantitative and qualitative. The quantitative part consisted of a thorough review of historic data (delimited to only four months) and a questionnaire, targeting the whole crew collective, was set up as a complementary qualitative analysis. In this thesis the work and result is presented. The result of the analysis shows that satisfaction felt by the crew cannot be directly compared to bid fulfillment as it is measured today. The major aspects of improving the PBS should include a simplification regarding mainly bid types, but also actions in order to increase the transparency of the system and awareness. The recommendation to SAS is to present statistics to crew for each bid type regarding number of placed bids, number of possible fulfillments and how much that is fulfilled thus visualizing the possibility to get a bid fulfilled. A revised range of bid types have also been recommended along with a few minor changes.

    A Collaboration in Product Service System for Telecom Networks: An "Orange and Ericsson case" study2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of the research is to study the “Orange and Ericsson case” while developing the method Actors and System Map. The interaction between actors within Ericsson’s Device Connection Platform is investigated in order to identify improvement opportunities in the interaction between the provider and the customer. To answer the purpose the following research questions was formulated:

    RQ1)  What type of actors may be involved in a telecom related IPSO?

    RQ2)  How can the connections between actors in the telecom related IPSO be illustrated?

    RQ3)  How can the Actors and System Map method be refined?

    In order to answer the research questions different methodologies were used for the analysing process. The research started with a widespread literature study to collect knowledge related to the area of Product Service System (PSS) and methodologies for identifying how actors interact with one another. Studying different mapping methods the conclusion was made that Actors and System Map was most suitable for this study.

    In the methodology background the previous selected method, Actors and System Map from an Integrated Product Service Offering (IPSO) perspective, was examined in order to be able to refine and improve the mapping method. Actors Map provides a visual and clear overview of the actors involved while a System Map shows the information flows and activities between the actors.

    To understand the interaction between the two companies, the definition of IPSO and the importance of value-based selling for a service offering are described in the theory background. Also, different ways of looking at a business model within the telecommunication industry is presented.

    Obtaining information regarding making an Actors Map and a System Map an improved mapping method was refined. The adaption of the method was divided into eight steps. The refined Actors Maps of the DCP shows the actors involved, how they are connected and their main assignments from each respondent’s point of view at Ericsson. The refined System Map shows what kind of information is transferred between the actors within the companies and between Orange and Ericsson. Both maps delivered as a decision basis will help identification of non-value giving links and non-optimal distances in the information flow for both companies.

    Manpower planning for airline pilots: A tabu search approach2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The airline industry faces some of the largest and most complicated optimization problems among all industries today. A large part of their costs iscrew costs and large savings can be made by efficient manpower planning. The research focus has been on the later steps in the planning process such as crew scheduling. The focus of this thesis is on the largely unexplored research area of staffing and transition planning for pilots. For the important question of which pilot should receive training to which position no solution strategy with optimization has, before this thesis, been presented. One reason for this might be that many complicated regulations concern this question, making an easily solved model impossible. I have developed a tabu search based algorithm with encouraging results. The algorithm was tested on data from Scandinavian Airlines. Compared to a reference algorithm based on commercial mixed integer programming software, the tabu search algorithm finds similar solutions about 30 times faster. I show how tabu search can be tailored to a specific complicated problem, and the results are good enough to not only be of theoretical interest but also of direct practical interest for use in the airline industry.

    Mapping of environmental KPIs2015Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aviation industry is facing many challenges concerning environmental effects associated to an overall increase in air travel. In order to analyse these environmental effects, the possibility for measurement in the areas connected to the aviation industry is essential. Metrics measuring progress towards meeting goals, called key performance indicators, are used in order to meet this requirement. The purpose of the thesis is to map and evaluate the various environmental key performance indicators that are utilised within European Air Traffic Management today, and the development underway for the future. Suggestions to LFV regarding suitable e-KPIs, and how they can be used within their organisation are also provided. Several organisations and initiatives, including the European Union, EUROCONTROL, Single European Sky, the International Civil Aviation Organisation and the Civil Air Navigation Service Organisation, as well as the British and French air navigation service providers, in addition to other stakeholders within the industry, have been investigated in terms of their work in the environmental area and which indicators they utilise. The investigation is based on a literature study and interviews conducted with stakeholders within previously mentioned organisations. Out of 39 indicators found during the mapping, seven remain after an initial selection and an analysis based on the utilisation of the SMART-model. In addition to the use of the SMART-model, the choice of suitable indicators is also based on the fact that the whole spectrum of a flight, meaning all phases, including planning, taxi-out, departure, en route, descent and arrival as well as taxi-in, should be taken into consideration.

    A comparative study between Emme and Visum with respect to public transport assignment2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Macroscopic traffic simulations are widely used in the world in order to provide assistance in the traffic infrastructure development as well as for the strategic traffic planning. When studying a large traffic network macroscopic traffic simulation can be used to model current and future traffic situations. The two most common software used for traffic simulation in Sweden today are Emme and Visum, developed by INRO respective PTV.

    The aim of the thesis is to perform a comparison between the software Emme and Visum with respect to the assignment of public transport, in other words how passengers choose their routes on the existing public transport lines. However, in order to make a complete software comparison the run-time, analysis capabilities, multi-modality, capacity to model various behavioural phenomena like crowding, fares etc. this will not be done in this comparison. It is of interest to study the differences between the two software algorithms and why they might occur because the Swedish Transport Administration uses Emme and the Traffic Administration in Stockholm uses Visum when planning public transport. The comparison will include the resulting volumes on transit lines, travel times, flow through specific nodes, number of boarding, auxiliary volumes and number of transits. The goal of this work is to answer the following objective: What are the differences with modelling a public transport network in Emme and in Visum, based on that the passengers only have information about the travel times and the line frequency, and why does the differences occur?

    In order to evaluate how the algorithms work in a larger network, Nacka municipality (in Stockholm) and the new metro route between Nacka Forum and Kungsträdgården have been used. The motivation for choosing this area and case is due to that it is interesting to see what differences could occur between the programs when there is a major change in the traffic network.

    The network of Nacka, and parts of Stockholm City, has been developed from an existing road network of Sweden and then restricted by "cutting out" the area of interest and then removing all public transportation lines outside the selected area. The OD-matrix was also limited and in order not to loose the correct flow of travellers portal zones was used to collect and retain volumes.

    To find out why the differences occur the headway-based algorithms in each software were studied carefully. An example of a small and simple network (consisting of only a start and end node) has been used to demonstrate and show how the algorithms work and why volumes split differently on the existing transit lines in Emme and Visum. The limited network of Nacka shows how the different software may produce different results in a larger public transport network.

    The results show that there are differences between the program algorithms but the significance varies depending on which output is being studied and the size of the network. The Visum algorithm results in more total boardings, i.e. more passengers have an optimal strategy including a transit. The algorithms are very similar in both software programs, since they include more or less parts of the optimal strategy. The parameters used are taken more or less into consideration in Emme and Visum. For example Visum will first of all focus on the shortest total travel time and then consider the other lines with respect to the maximum waiting time. Emme however, first focuses on the shortest travel time and then considers the total travel time for other lines with half the waiting time instead of the maximum wait time. This results in that less transit lines will be attractive in Emme compared to Visum. The thesis concludes that varying the parameters for public transport in each software algorithm one can obtain similar results, which implies that it is most important to choose the best parameter values and not to choose the "best" software when simulating a traffic network.

    Executive functions and Planning in everyday life: Assistive Technologies for Cognition and their lack of support for children with Attention Deficit / Hyperactive Disorder2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The evaluation of how Assistive Technologies for Cognition (ATC) serve their purpose in providing support for children with Attention Deficit/Hyperactive Disorder (AD/HD) is limited and it is not clear how to best support the cognitive functions in order to help the individual increase task performance in everyday life. This thesis sought to scrutinise how families with at least one child diagnosed with AD/HD incorporate ATCs in their daily life in order to cope with appurtenant difficulties. An online survey, answered by 92 caregivers for children with AD/HD, attended to the cognitive abilities in need of support, the usage of ATCs, and how ATCs supported the executive functions in everyday planning. The results reveal that children encounter difficulty in dealing with cognitive ability, executive functioning and causal inference when it comes to planning in everyday life situations, which relates to lower levels of independence. Executive functioning and causal inference is negatively correlated to number of symptoms of AD/HD. The ATC is not satisfactorily supporting the cognitive functions, which results in another person by default being the one who sets up the ATC, and the child merely follows the instruction. The results has been processed into a table containing concepts which is suggested to be considered both when developing, as well as evaluating, ATCs for children with AD/HD.

    Preventing maternal mortality: - Nurses’ and midwives’ experiences from Tanzanian maternal health care services.2013Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Half a million women died during pregnancy or childbirth in 2005. Bleeding, infections, high blood pressure, obstructed labor, unsafe abortions, malaria and HIV/Aids were the main causes. Tanzania is a highly affected country with 460 maternal deaths per 100 000 live births. Nurses and midwives play an important role in preventing maternal mortality.

    Purpose: The aim of this study was to explore and analyze nurses’ and midwives’ experiences of maternal mortality prevention on the Tanzanian island of Unguja.

    Method: Interviews with nine nurses and midwifes from four different hospitals and health care facilities were conducted with the assistance of an interpreter. A structural analysis designed by Ricoeur was undertaken.

    Results: The findings suggest that family planning, a more accessible health care, referral of severe cases, medical interventions, health education, community resource persons and involving fathers in maternal health care are preventive strategies that can reduce maternal mortality.

    Conclusion: To further improve the quality of maternal mortality prevention further knowledge aboutindividual differences in learning from health education is needed.  Involvement of all fathers in maternal health care should also be considered. Training of unskilled personnel is believed to improve early identification of life-threatening complications and thereby reduce maternal mortality.

    Continuing education: preparing patients to choose a renal replacement therapy.2015In: Journal of Renal Care, ISSN 1755-6678, E-ISSN 1755-6686, Vol. 41, no 1, 62-75 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Patients with progressive chronic kidney disease face a series of treatment decisions that will impact the quality of life of themselves and their family. Renal replacement therapy option education (RRTOE), generally provided by nurses, is recommended by international guidelines

    OBJECTIVES: To provide nurses with advice and guidance on running RRTOE.

    DESIGN: A consensus conference.

    PARTICIPANTS: Four nurses, 5 nephrologists and 1 clinical psychologist (9 renal units; 6 European countries) from units that had extensive experience in RRTOE or were performing research in this field.

    APPROACH: Experts brainstormed and discussed quality standards for the education team, processes, content/topics, media/material/funding and quality measurements for RRTOE.

    RESULTS: Conclusions and recommendations from these discussions that are particularly pertinent to nurses are presented in this paper.

    CONCLUSIONS: Through careful planning and smooth interdisciplinary cooperation, it is possible to implement an education and support programme that helps patients choose a form of RRT that is most suited to their needs. This may result in benefits in quality of life and clinical outcomes.

    APPLICATION TO PRACTICE: There are large differences between renal units in terms of resources available and the demographics of the catchment area. Therefore, nurses should carefully consider how best to adapt the advice offered here to their own situation. Throughout this process, it is crucial to keep in mind the ultimate goal - providing patients with the knowledge and skill to make a modality choice that will enhance their quality of life to the greatest degree.

    Carbon Capture and Storage: Major uncertainties prevailing in theFutureGen project2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Carbon Capture and Storage (CCS) is an old technology matrix with new concept to mitigate climate change while utilizing fossil fuels by advancing the technology. The various level of advancement in technology has been successfully demonstrated in some part of the world. However the technology has inherent uncertainty of not having commercial CCS plant. Efforts to make CCS commercially viable unfold uncertainties in numerous aspects of CCS technology. Beside the uncertainties in technology many barriers restrain CCS to become a successful climate mitigation technology. However the growing energy demand and urgent need to mitigate climate change through emission reduction favours CSS as transition to clean energy production. FutureGen 2.0 is the only large commercial scale CCS project, initiated in 2003 to test the commercial viability of the technology and to meet the U.S energy demands besides emission reductions target. The project resurrection in 2010 as FutureGen 2.0 after FutureGen termination in 2008 provides an opportunity to understand and analyse numerous uncertainties. However through document analysis only major three uncertainties i.e. policy and regulatory, economic and financial and public acceptance uncertainties are identified and analysed. The interlinkages between these uncertainties are also analysed. The study results show that above uncertainties constrained the project engendering new uncertainties i.e. timeframe uncertainties. This study also provides an insight about the sustainability implication of CCS by evaluating economic, environmental and social impact of CCS technology. It is still early to term the CCS as Sustainable technological innovation however for many years CCS would upset and restrain investment in other clean energy technologies like Renewable technology system. This study gives an input in sustainability of CCS and technological assessment study. This study is helpful in managing uncertainties and planning new CCS projects.

    En jämförelse mellan att utföra en värdeflödesanalys av produktion respektive planering: Fallstudie på ABB ROBOTICS Västerås2013Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.

    An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.

    In this work, a comparison is made between the introduction of value stream analysis on production and planning. This has been done through a case study at ABB Robotics. On this case study a value stream analysis has been made on the planning part of ABB Robotics and the part of the factory floor manufacturing the control cabinets of the robots. The purpose of the performance was to create an understanding of the similarities and differences that exist in the application of value stream analysis on production and planning. The case study has been made based on the current literature available on the subject. The literature has then been reviewed critically, based on the differences and similarities shown by the performed case study.

    Based on an analysis of the results from the case study, several conclusions were drawn and reflected over taking into account the existing literature. Conclusions drawn from the study, questions the existing literature's critical attitude to the method. Critical review is important at this situation because it is a new method and much proof, that it is properly functioning, does not yet exist.

    The study mentions that value stream analysis of planning is not always relevant. The interest of the method depends on the type of business and its customers' needs. For a company where the lead time of the planning part of the company is not of great importance to the customer’s value stream mapping is not interesting to apply. The application of value stream analysis is much more complex and time-consuming according to the study and therefore it is not always worthwhile to use the method.

    Utformning av ny verkstadslayout för att öka produktiviteten och minska slöseri: En fallstudie på DMB Scania AB2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis has been carried out at as a single case study at Scania AB in Södertälje, Sweden. The purpose of the study was to examine possibilities to increase the productivity and eliminate waste through the implementation of a new workshop layout at Scania’s crankhaft production. The thesis was based on a literature study where different lean principles, production systems and layout shaping were covered as well as an empirical study at Scania AB.

    The case study was divided into four phases:

     Mapping of present state

     Layout shaping

     Analysis of the proposed layout

    A data collection was carried out before mapping the current state. The data collection consisted of both given secondary data from the case company and the primary data from own measurements, observations and interviews in order to gain credibility to the study. With the collected data an analysis of the current state was done where problem areas were identified and documented.

    The analysis mainly showed that Scania AB had problems with long lead times and difficulties to maintain FIFO due to high WIP-levels. A significant reason to the high WIP-levels was the result of a big inventory between the two organisational departments in the workshop.

    The identified problem areas, cycle times and future sale forecasts were then used as input parameters to develop a new layout using Muther’s (1968) method Systematic Layout Planning (SLP).

    The final result rendered in a new layout proposal which increased the productivity with 37% and eliminated waste in different areas. The lead time was estimated to decrease from the initial 5,4 days to 1,5 days with a significant decrease in the inventory mentioned above.

    Development of the S&OP process at Seco Tools AB: Aligned with today´s supply chain planning processes 2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background:

    Companies strive to produce as close to customer demand as possible to reduce the cost, inventories, etc. One process that deals with this issue of balancing demand and supply is Sales & Operations Planning (S&OP). Seco Tools is a company with their head-office located in Fagersta, Sweden, which is experiencing high inventory levels and a need of cutting cost. The ongoing project Supply Chain Planning at Seco Tools resulted in the implementation of a new software which enables them to improve demand, inventory, and supply planning. As a result of the improved planning ability, a new S&OP process is developed and in need for improvement.

    Purpose:

    The purpose of this thesis is to evaluate the current S&OP process from the Supply Chain Planning project and to suggest future improvements for Seco Tools AB.

    Research objectives:

    1. Study and describe the current S&OP process at Seco Tools.

    2. Analyse and identify differences in Seco Tools’ S&OP process compared to the literature and a benchmark company.

    3. Perform deeper analyses within financial integration and the use of KPIs in Seco Tools´ S&OP process.

    4. Suggest future improvements to Seco Tools regarding their S&OP process based on the identified differences from research objective 2 and the deeper analysis from research objective 3.

    Method:

    The planning report set the framework for the carrying through of the thesis. A literature study regarding S&OP and a case study performed at Seco Tools regarding their S&OP have been done in parallel. Seco Tools’ S&OP process has been studied and described with the help of interviews, observations, and internal documents. Analysis was made where Seco Tools S&OP was compared to the theoretical S&OP and the S&OP at AstraZeneca. The analysis led to recommendations to Seco Tools regarding improvements in their S&OP process.

    Conclusions:

    Two opportunities for improvement were highlighted during the analysis of Seco Tools S&OP. They were financial integration and the use of cross-functional KPIs covering all the departments that were suggested to be involved in S&OP at Seco Tools. Seco Tools should integrate their finance in the process to compare S&OP against the business plan, and the company’s strategy should be well understood by the participants in S&OP. The knowledge of the company’s strategy together with the right authorities in the process will improve the decision making in Seco Tools’ S&OP. Seco Tools also need to implement an S&OP scorecard with KPIs that covers all departments in the company and the strategy as well. This helps to further develop cross-functionality and to early on make root cause analysis of identified problems. Cross-functionality and KPIs are believed to be general recommendations that all companies can use as well, not only something that Seco Tools can take advantage of. A template for an S&OP scorecard especially for Seco Tools has been made. It contains 16 cross-functional KPIs covering all steps and departments involved in S&OP at Seco Tools.

    The process of knowledge transfer in mergers and acquisitions: A single-case study of a Swedish manufacturing organization2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Mergers and acquisitions (hereinafter referred to as M&As) are increasing in their importance and they have become a commonly applied strategic option for organizations. A major reason for an acquisition is often the objective of gaining new knowledge from the acquired company and then transferring that knowledge among other parts within the acquiring organization. Furthermore, the explicit and tacit nature of knowledge is essential for the transfer of knowledge during M&As. Also, the process of knowledge transfer is dynamic and complex and thus, numerous challenges can arise along the way. As proved by the literature individuals are the key factors, which constrain the transfer of knowledge in M&As.

    Aim: Despite the extensive existing literature in the area of knowledge transfer, it provides a rather static view and thus, less is known about the dynamic process nature of knowledge transfer in M&As. Therefore, the purpose of this qualitative research is to gain deeper understanding of how the process of knowledge transfer evolves over time and how employees constrain it within the acquiring organization during the post-acquisition phase in a merger and acquisition (hereinafter referred to as M&A). In addition, the redefined models in this thesis provide a foundation for future research.

    Methodology: This thesis is based on a qualitative single-case study method, which builds upon empirical data of an anonymous Swedish international organization (hereinafter referred to as Globex) operating in the manufacturing sector. Theoretical constructs are applied in order to form a generalization. First-hand information is primarily used for this thesis, which was collected in the form of in-depth interviews with the employees of Globex. In order to present the analysed data in a more understandable and visible manner, tables and graphs were applied. Furthermore, our research method is based on the iterative grounded theory, which deals with organizational process research. Thus, we were able to analyse the dynamics in the knowledge transfer process despite its high level of complexity. Due to this complicated essence of the knowledge transfer process, we were unable to explore it entirely and could not acquire all necessary information. However, we still contribute with novelty to the academic society, as previous research explores the static view of knowledge transfer and our research relies on its dynamics.

    Results: The process of knowledge transfer and how it evolves is illustrated with the necessary phases for its accomplishment. The first model, which demonstrates the dynamic nature of the knowledge transfer process during M&As, is presented. In order to positively influence the transfer of knowledge, enablers should be applied. The second model highlights the importance of planning the process of knowledge transfer within the post-acquisition phase during M&As. Lastly, constraints from the employees’ side can influence the transfer of knowledge. The importance to consider enablers and constraints during the knowledge transfer is also emphasised.

    Theoretical implications: We urge that more research should accentuate on the process nature of the knowledge transfer and should further explore its dynamics and complexity especially in the context of organizational changes, such as M&As.

    Managerial implications: Managers should understand the evolving nature of the knowledge transfer process and strengthen their focus on the planning phase of knowledge transfer in order to minimize the issues during the post-acquisition phase.

    The Never Ending Shower: planning ability, intellectual disability and cognitive artifacts2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Persons with intellectual disability have been found to perform more poorly on tasks, demanding the use of executive functions like planning, than their peers. This study investigated difficulties with planning, and how problems with planning ability can be supported by using cognitive artifacts to help performance on activities in everyday life, for adolescents with intellectual disability. The approach taken is one of situated cognition, where the natural environment plays a big role, to see if the same difficulties arise as results from traditional research has shown. The traditional view focuses a lot on executive functions, and experimental studies in controlled settings and often suggests interventions and practice of certain functions to get better abilities. Another way is to focus on the use of cognitive artifact, to support problematic abilities, and to get a well-rounded understanding of how the problems actually appear in everyday life, the alternative view of situated cognition is a way to go. The data was gathered through interviews and surveys with the individual’s parents and analyzed through categorization and a repeated measures ANOVA, with a bonferroni corrected post hoc test. Results show several problematic areas, and that there is a difference in how problematic these areas are estimated to be when it comes to planning in everyday situations. It is discussed how the natural contexts helps knowing what planning really means for the group, as well as how it can help finding properties in cognitive artifacts that can help raise the level of independence in planning related tasks.

    Inre tal hos barn med utvecklingsstörning: Finns det ett samband mellan inre tal och storleken på ordförråd?2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: When children are faced by a cognitive challenge they often speak out loud to themselves. This is a common strategy in five year old children and is called private speech, which gradually, is developed into a silent form called inner speech. Inner speech is essential in several cognitive tasks including planning and problem solving, and is also involved in the working memory, particularly in the phonological loop. Children with intellectual disabilities have a limitation in the capacity of the working memory and in the phonological loop. The capacity of the working memory and the development of the phonological loop have a big importance in the acquisition of the vocabulary, therefore a limitation or delay in these skills lead to a delay in the vocabulary.

    Aim: The purpose of this study was to investigate the inner speech in children with intellectual disabilities and to investigate the correlation between the inner speech and the dimension of the active and passive vocabulary. 

    Method: 28 children participated. The target group consisted of 14 children with mild to moderate intellectual disabilities aged 8:4-16:0 years. The control group consisted of 14 children with typical development aged 4:8-8:6 years. The two groups were matched according to their test results on Raven's Colored Progressive Matrices. The active vocabulary was tested with Boston Naming Test and the passive vocabulary was examined with the Peabody Picture Vocabulary Test. To examine the inner speech and memory strategies the European Picture Span Study was used.

    Results: The result showed that the children in the control group have a bigger passive and active vocabulary compared to the target group and that there is a correlation between having a big vocabulary and using a more mature strategy in the control group. The target group use phonological strategies to a smaller extent than the control group, but they seem to have developed a consciousness regarding their use of strategies. The analysis also shows a significant correlation between span level and the size of the passive vocabulary in the target group, whilst there is a significant correlation between the span level and the active vocabulary in the control group.

    Climate Change Vulnerability Assessment for Sustainable Urban Development: A Study on Slum Population of Kota, India2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The urban centres are becoming more vulnerable to climate change because of the rapid urbanization and the inequality of urban development. This study assesses the urban vulnerability in an integrated approach focusing the slum people as the targeted group. The slum people are severely exposed to climate risks in terms of city‟s overall development. The negative indications of the indicators of person‟s vulnerability represent their high sensitivity to the adverse impact of climate change. The determinants of adaptive capacity also confirm that the slum people are more vulnerable to climate change with having lower adaptive capacity; though, the city is possessing high development indexes. In this context, an institutional structure is developed to build multi-level urban climate governance with the involvement of all relevant stakeholders based on the case study and literature review to integrate the vulnerable group in development planning for climate change adaptation.

    Produktionsplanering i komplexa projekt2014Independent thesis Basic level (university diploma), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Att ha samordningsansvaret i ett projekt som Framtidens US innebär stor fokus på planering och samordning. Beställaren har från början upphandlat en tredjepartslogistiker som ska ansvara för materialhanteringen istället för att huvudentreprenören skall göra detta. Syftet med fallstudien är att undersöka om produktionen upplevs som mer effektivare genom att tredjepartslogistikern ansvarar för materialförsörjningen. Entreprenörernas sätt att planera på har undersökts för att se hur de arbetar i mer omfattande projekt som Framtidens US som är ett känsligt område. Fallstudien visar att de involverade entreprenörerna ser positivt på hur logistikupplägget fungerar samt att det varit ett bra alternativ för att effektivisera materialförsörjningen.Dessutom har logistikupplägget bidragit till effektivisering av varje enskild arbetare. Resultatet visar även att planeringen har varit komplicerad att utföra i vissa fall då den skiljer sig från ett vanligt byggprojekt. Framtidens US projektet är ett projekt där samarbete mellan olika medverkande parter är viktigt för att uppnå ett bra resultat. De påvisade resultaten från fallstudien pekar på att det skulle kunna behövas ett annat sätt att planera på i framtida liknande projekt.

    Operationsprocessen: operationsplaneringssystems betydelse för patientsäkerheten vid kirurgi 2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Patient safety is an important part in the performance of good quality in healthcare and particularly in critical areas like anesthesia and surgery. The process of surgery can be supported by an operating room information system, but there is no adequate description of how a system like this will support a safer care of the patient.

    Purpose: The aim of the present study is to describe the process and importance of an operating room information system for the patient safety in operating rooms from the perspective of employees.

    Method: An empirical study with a qualitative onset was implemented and analyzed using directed content analysis according to Hseih & Shannon. Twenty six interviews were performed from nine different positions during the process of surgery in three different hospitals in mid- and southern Sweden.

    Results: Operating room management included planning, surgery and evaluation. Extern planning was handled by the surgery ward or reception and intern planning by the surgery department. To complete the process there was an inter-department coordination and planning. Changes and insufficient planning had to be taken into account during this process of planning surgery. Executed planning functioned as the working document during the day of surgery. Evaluation was considered as mostly production-oriented and patient-related evaluation was missing. Two areas emerge from patient safety, perspective and significance. The importance of an operating room information system related to patient safety was information, safety controls, organization and changes.

    Conclusion: Patient safety was guaranteed by employees who worked in the process of surgery and not by the operating room information systems. Development of safety functions in operating room information system may improve patient safety.

    Förutsättningar och utmaningar för det regionala klimatanpassningsarbetet i Sverige: En intervjustudie med klimatanpassningssamordnare2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Through qualitative interviews with climate adaptation coordinators at Sweden's county administrative boards, this study identified several aspects that affect the prerequisites for the regional climate adaptation work. 14 out of the 21 climate adaptation coordinators were interviewed in this study. After the interviews were conducted, we compiled important aspects that the informants shared. The results of this study shows that the national governance is rather vague. We can also see a weakness in how the question has come to the fore in other units at the county administrative boards as well as how the cooperation with municipalities and other governmental agencies has worked out. Another problem that exists is that the municipalities' lack of resources, which affects the degree to which they can implement climate adaptation actions. This study also shows that the climate adaptation coordinators unit placement affects, in large degree, in what way the question regarding climate adaption is handled. As the majority of climate adaptation coordinators are placed in a unit with a specialization in community planning, the Swedish regional climate adaptation work tends to focus on community planning. Furthermore, we establish that all the county administrative boards have different prerequisites for this task, through both a large variation in the allocation of funds, but also in vulnerability to climate change.

    På spaning efter integration: En studie om integration mellan marknadsfunktioner och logistikfunktioner inom svenska detaljhandelsföretag2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background

    Previous studies highlight the importance of integration between the marketing function and logistics function since it leads to several bene- fits for an organization. For example, an organization can in a more efficient way meet customers’ expectations regarding product availability and delivery service when the functions are integrated. It only exists limited studies on how integration between marketing functions and logistics functions appear in practice. An empirical gap in knowledge regarding integration between marketing functions and logistics functions in Swedish retail companies was detected. This knowledge gap has been the basis for this study.

    Aim

    This study aims to analyze whether or not the marketing functions and the logistics functions within Swedish retail companies are integrated, and in that case, to analyze how they are integrated.

    Execution

    To achieve the aim of this study, interviews were conducted with employyees of the marketing function and the logistics function within three Swedish retail companies. These companies were Cervera, Glitter and KappAhl. Observations were made in two of each company's stores to examine the availability of current campaign products. During the observations interviews were conducted with the stores manager. Finally, interviews were made with industry participants to investigate their experience of integration between marketing functions and logistics functions within the retail industry.

    Conclusion

    This study indicates that market functions and logistics functions within Swedish retail companies can be considered integrated to some extent but it also indicates that the integration can be improved. The functions are primarily integrated by exchanging documents, sharing resources, having a desire to achieve goals together and by sharing a vision and having a common planning. During periods with product campaigns it is important with an effective integration of the two functions since they need to share information. In Swedish retail companies the integration between the functions is affected by the organizational culture, organizational structure, communication, information systems and the physical placement of the functions.

    Structuring Lean Thinking in the Radio Access Network Area2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Customer’ demands, higher quality, faster and safer deliveries are some reasons for unexpected changes in the organizations. It has incremented complexity and cost. Lean production is known as a methodology to make improvements in manufacturing areas such as mentioned above and it is focused on the process of a product. But, Lean Thinking is a management strategy to make improvements in the process of a product or service and it is based on five principles. It allows having the process close to the customer eliminates tasks that do not add value and produces with low costs and high quality. However, there are some concepts ambiguous to be applied effectively to the Radio Access Network area in wireless telecom industry as a service company. Radio Access Network area transmits Radio frequency (RF) signals from the Radio Base Station (RBS) to the user equipment (UE) or mobile phone and is an area to present dynamic changes by high technology innovation. Therefore, the aim of this study is to identify improvements through for the Radio Access Network area.

    This thesis was structured to know how the five Lean principles and Lean tools can be used in the Radio Access Network area and the benefits that it could have. The study was realized through a qualitative research and five semi-structured interviews. A manager, team leaders and engineers of wireless telecom industry vendor and operators were the participants for this study.

    The results of major impact for Lean principles and Lean tools were VSM and Flow principles and Waste as Lean tool found for the Radio Access Network area. Project definition, resource planning and VOC were some improvements revealed for VSM principle. Furthermore, faster and optimal tools, training for engineers, knowledge in software and employee empowerment were some improvements found for Flow principle. Waste Lean tool showed some improvements found on customer’s focus, clear communication and waiting time reduction. Cross functional teams were other aspects that provided quality performance in the projects.

    This study seemingly is a good start for making decisions and for the high technology innovation and dynamic changes for telecom service companies.

    Parkering i Norrköping: Processen att skapa ett mobilt användargränssnitt för att underlätta reseplanering2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With a series of prestigeous events such as the Bråvalla Music Festival and the European premiere of Harry Potter: The Exhibition, Norrköping will, during the summer of 2014, attract many tourists. As a visitor, it may be difficult to locate appropriate parking spots in situations like these. Norrköpings Municipality currently has a map on their website with an overview of parking spots in the central areas of the city. This map, however, is only suited for viewing on big screens. To search for the map on a mobile device, find an appropriate parking and then correctly navigate to its location may serve difficult for a user who is new to the town or pressed for time.

    The purpose of this study is to create a user-friendly interface design for a mobile application that aims to facilitate the parking process for drivers who live in, or are visiting, Norrköping. The study uses a sequential mixed method approach and the design process is based on a goal-directed and user-centered design. Surveys, interviews and usability testing have been employed to collect research in order to create an interface that meets the needs of the user.

    The study resulted in the creation of an interface for a parking application that can be used for planning purposes as well as navigation. Choices for design and interactivity are based on the users' goals and preferences. The study concludes that a stressful situation requires information to be clear, easily understood and call for minimum effort from the user's side. Redundant information should be removed and the steps it takes to obtain information should be reduced.

    Different users have different attitudes towards the use of mobile applications for planning and parking. The majority of interviewees would in a similar situation rely on a Google search for information. From this we can conclude that the easiest solution would be for Norrköping's Municipality to create a mobile website with information about parking in the city. However, in order to reach a broader target group and to incorporate certain complex functions and features, the creation of an application becomes necessary.

    Hinder & möjligheter med dagvattenhantering: Fallstudier över Linköping och Norrköping kommuns arbete med alternativ dagvattenhantering2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today’sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012). The precipitation over Sweden is expected to increase 10-20% over the next century (SMHI, 2009). Increased precipitation may cause temporary capacityloss in pipe-based storm water system with flooding in sensitive areas as a result (Östlund &Lagerblad, 2011). To decrease the potential stress on traditional storm water systems,sustainable urban drainage systems have started to be developed (Viklander & Bäckström,2008). The era of traditional storm water systems has reached a breaking point and moresustainable storm water systems has become more desired as a complement to today’ssystems (Cettner et al, 2014; Semadeni-Davies et al., 2007). In order to build an increaseunderstanding sustainable storm water management it is decisive to investigate what obstaclesthat municipalities has to tackle, regarding storm water management. This study aims toanalyze problems that may occur concerning storm water management including whatchallenges and possibilities that municipalities have to face. The study is based on qualitativeinterviews with informants in the municipalities of Linköping and Norrköping to see how theyare working with storm water and sustainable storm water management. The conclusions ofthe study is mainly, the need for a more pronounced governance, a more explicit demandconcerning laws and regulations, in particular the Swedish planning and building act, acommon vision about how storm water management practices should be handled and finallyquestions concerning how storm water should be handled in an early stage in the planningprocess. This is the main factors to facilitate the work with sustainable urban drainage system.

    Remote Tower Centre - Configuration and Planning of the Remote Tower Modules2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today, many small aerodromes have a hard time surviving economically, and amongst the largest cost is air traffic control. Airlines are cutting costs where they can, and many times this affects the aerodromes as well, e.g. when airlines decide to park remotely instead of at the gate. The project called Remotely Operated Towers, initiated by SESAR and run by Saab and LFV, is aiming to address this problem. The project revolves around remotely providing ATS to aerodromes where it is deemed suitable. A big challenge in this project is how to assign aerodromes to remote tower modules in the remote control centre. There are many ways to do this, but there is only a few ways to do it to achieve the least amount of modules. This thesis aims to find an optimal solution to the challenge mentioned above. The thesis resulted in a model where the user can provide the input of choice, i.e. aerodromes with associated ATS operating hours and movements, for a specific period – and receive the assignment schedule for the modules, saying exactly which aerodrome are to be controlled by which module at what time.

    Environmental Impact Assessments in Detailed Development Plan Processes: An Adequacy Analysis2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A detailed development plan (DDP) is a legally binding plan that regulates the municipalities land use on a detailed level. The purpose with the DDP is to evaluate the suitability for development on land access, in order for municipalities to manage spatial planning and minimize environmental harm. If a DDP would likely cause a significant impact on the environment, an Environmental Impact Assessment (EIA) has to be produced.

    The aim of this thesis was to investigate how DDP and EIA processes are working on a local level in Sweden, and how the quality is reflected in the processes. More specifically, I investigated the role of EIA actors involved in the DDP process, as well as whether these processes are inadequate from an environmental conservation perspective. To investigate these issues, a document study was conducted as well as an interview study.

    The results from the study presents several shortcomings in both processes; examples of shortcomings were the lacking knowledge among the DDP and EIA actors in how to conduct the process, as well as interpreting and understanding the law.  Other observed shortcomings were the different levels of engagement among the plan administrators, the EIA performers and the County Administrative Board reviewers. Three important factors were recognized for achieving good processes. Firstly, the people involved need to have broad knowledge and good qualifications. Secondly, the actors must be able to communicate in a good and clear manner. Lastly, the third factor is a good process leader who brings together the DDP and EIA process.

    MoSync för multi-plattformsutveckling till smartphones2014Independent thesis Basic level (university diploma), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    This is a thesis that is done on behalf of Meal Planning Concepts AB. The goal was to developa native multi-platform application for smartphones and tablets that would work on Android and iOS, and share database with their current web system. The functionality would be based on that found on their website. The application was developed in MoSync which is a framework that is capable of multiplatform development. The purpose with the thesis was also to evaluate MoSync during the project and present other similar tools and how they behave compared to MoSync. The report showcases the work and problems encountered during the development of the application as well as the end result. The pilot study showed that there were many othertools that focused on support for multiple platforms. Frameworks raised were jQuery Mobile, PhoneGap and Marmalade where the latter was the tool that was the most similar to MoSync. MoSync proved to be a framework in which all the company's requirements for functionality could be met except for a design simplification. Some drawbacks were that it was slightly buggy and that the community was small.

    Decentralized Urban Wastewater Reuse in China: - with Focus on Grey Water2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Grey water reuse has attracted more and more attention among researchers and professionals in recent years. As most of the Chinese cities are undergoing the process of fast urbanization and economic development, many water-related problems have occurred and urban water resources management has become a strategic issue. The urge to reconsider the conventional ways of utilizing water and discharging the wastewater in cities is calling. As a relatively simple and flexible way, decentralized grey water reuse system can help to make the first step in achieving a sustainable urban water management. However, whether it is feasible in China is still a question. This paper aims at looking for the answer based on a survey and interviews with professionals in the fields from different Chinese cities. The result shows “reuse” as one of the solutions of solving water shortage and achieving sustainable water management is not as simple as one may think. In general, decentralized urban grey water / wastewater reuse is not easy to flourish in China in the near future though most of the respondents hold a positive attitude about reuse itself. To explain this difference between attitude and actual planning we need more historical, political and social-economic understanding with a touch of “Chinese characteristics”.
