    Architectural or modular innovation? Managing discontinuous product development in response to challenging environmental performance targets2003Inngår i: International Journal of Innovation Management, ISSN 1363-9196, E-ISSN 1757-5877, Vol. 7, nr 1, s. 1-26Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    By adopting challenging targets on environmental performance, pro-active industrial firms may push themselves towards discontinuous product innovation. Such innovation can be understood as being either architectural, i.e. arranging components in new ways, or modular, i.e. introducing new technologies in specific components or subsystems. We argue that these two dimensions of discontinuous change call for some specific managerial responses. Architectural innovation challenges the whole engineering organisation, making it necessary to focus development efforts on technological interfaces, whereas modular innovation has a more isolated effect, making specialisation and co-ordination over organisational boundaries particularly important. Altogether, our analysis highlights the importance of adapting the project organisation to the development task and addressing part-whole relationships when managing innovation in established products and systems, something that becomes increasingly important in the strive towards sustainable development.

    From CoPS to mass production? Capabilities and innovation in power generation equipment manufacturing2005Inngår i: Industrial and Corporate Change, ISSN 0960-6491, E-ISSN 1464-3650, Vol. 14, nr 1, s. 1-26Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article presents a case study of small, distributed electrical power generators, representing a potential substitute for large power plants, and raises questions regarding the ability of established manufacturers to manage this kind of technological transition. The analysis demonstrates that the step from experimental R&D to commercial production is particularly difficult for the incumbents. This observation is explained by showing that whereas manufacturing of large power plants rests upon extensive systems integration capabilities, distributed generators are based on a 'plug-and-play' logic. © ICC Association 2005, all rights reserved.

    Model Based Definition within relocation of aircraft production2012Inngår i: ICAS 2012 CD-ROM PROCEEDINGS. 28TH CONGRESS OF THE INTERNATIONAL COUNCIL OF THE AERONAUTICAL SCIENCES 23 - 28 September, 2012, Brisbane, Australia, 2012, s. 1-9Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The purpose of the paper is to discuss how relocation of production can be affected when MBD is applied. The research is performed from a view point of production relocation; the focus is not on MBD as a method. The paper is based on a literature review combined with empirical data from an industrial study at the Swedish enterprise Saab Aeronautics. It was hard to find gaps in the literature since no literature covering the aim of the research was found. Important subject of discussion was that update or creation of MBD production documentation can decrease the amount of tacit knowledge at the sender and help the possibility to differentiate off-line learning from on-line learning, which can save both time and cost.

    Technology Transfer within Related Offset Business: From an Aircraft Production Perspective2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The aircraft industry is viewed as a prestigious industry by many countries. Emerging economies regard the establishment of aircraft production capabilities as contributing to their competitiveness and technological development. Therefore, in the defence aircraft industry, politics play a key role in competitiveness. Governments can strategically trade market access for technological development, often in the form of offset business. “Offset” is defined as an agreement in which a large system is bought and the seller assumes obligations that both benefit the buying nation and have long-term effects on the development of the buyer’s national industry. When the offset obligations are directly connected to the product or system sold, they are called “related offsets”. The realization of an offset agreement is in most cases including some form of technology transfer. Technology transfer is the transfer of technology from a sending company, to a receiving company, where it is implemented and adapted to use.

    The empirical data presented in this thesis were gathered through six in-depth studies performed at the unit for aircraft production at the Swedish company Saab. The findings from the studies are presented in six appended papers. The objective of this thesis is to extend the current understanding of technology transfer realization connected to related offsets within the defence aircraft industry. The research objective is fulfilled through the addressing of two research questions. The first research question aims to identify factors that can have a major effect on technology transfer realization in the research context. As an answer to the first research question. Following factors were identified: Capability gaps, Knowledge transfer, The purpose of related offset business, Seller’s fulfilment of offset obligations before contract termination, Related offset business include hierarchical levels, Related offset work package identification to meet the buyer’s request, and Assessment of the receiver in two steps, and finally Cultural and communication challenges.

    These factors set the basis for research question two. The second research question addresses how to manage future related offset technology transfer realization connected to aircraft production. As an answer to the second research question, a structured related offset process and facilitation tools for managing capability gaps between the sending and the receiving company was presented. The purpose of the suggested structure is to maintain the link between the negotiated related offset agreements and the employees, working to achieve the agreement within the realization of the technology transfer.

    2011 (engelsk)Inngår i: Computer Supported Cooperative Work in Design (CSCWD), 2011, IEEE , 2011, s. 835-841Konferansepaper, Publicerat paper (Fagfellevurdert)
    Abstract [en]

    The research within this paper identifies three main categories of cross-cultural communication challenges within international transfer of aircraft production. The first category is organizational structure, hierarchy and delegation of responsibility the second category is consensus behavior and avoidance of conflicts and the third category is individual motivation factors. Furthermore, the paper discusses the need for specific types of cross-cultural training that can be one solution for reducing the problems and difficulties that cultural challenges may induce. The case study indicates that it is important for Aeronautics, a Swedish enterprise, to apply organized cross-cultural training in combination with technical training. To secure the presence of cross-cultural training, suitable types of cultural training could be included in the working process/routine for how to conduct a production transfer.

    2013 (engelsk)Inngår i: Received wisdom, kernels of truth, and boundary conditions in organizational studies / [ed] Daniel J. Svyantek and Kevin Mahoney, Information Age Publishing, 2013Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    This volume of the Research in Organizational Sciences is entitled "Received Wisdom, Kernels of Truth, and Boundary Conditions in Organizational Studies". Received wisdom is knowledge imparted to people by others and is based on authority and tenacity as sources of human knowledge. Authority refers to the acceptance of knowledge as truth because of the position and credibility of the knowledge source. Tenacity refers to the continued presentation of a particular bit of information by a source until this bit of information is accepted as true by receivers. The problem for organizational studies, however, is that this received wisdom often becomes unquestioned assumptions which guide interpretation of the world and decisions made about the world. Received wisdom, therefore, may lead to organizational practices which provide little or no benefit to the organization and, potentially, negative organizational effects, because this received wisdom is no longer valid. The 14 papers in this volume all, in some way, strive to question received wisdom and present alternatives which expand our understanding of organizational behavior in some way. The chapters in this volume each strive to present new ways of understanding organizational constructs, and in so doing reveal how received wisdom has often led to confirmation bias in organizational science. The knowledge that some perceived truths are actually the products of received wisdom and do not stand up to close scrutiny shakes up things within research areas previously thought settled allowing new perspectives on organizational science to emerge

    Abstract [en]

    The purpose of the study is to investigate factors that are important for the transition from 2D to 3D by Model Based Definition (MBD). Within MBD, 3D models are used as sources of information for design, production, distribution, technical documentation, services and the overall product lifecycle. The introduction and development of MBD at Aeronautics can be described in five transitions that illustrate how knowledge enhancement from project to project and between the projects and the linear organization has evolved. The largest challenges have been in the start-up of the transitions, people are gathered with different prerequisites, seeing solutions or problems from different perspectives.

    2016 (engelsk)Inngår i: Journal of Manufacturing Technology Management, ISSN 1741-038X, E-ISSN 1758-7786, Vol. 27, nr 5, s. 640-661Artikkel i tidsskrift (Fagfellevurdert) Published
    Abstract [en]

    Purpose – The purpose of this paper is to explore how capability gaps can be identified and how they can be dealt with in aircraft technology transfers in future offset deals.

    Methodology – The study is based on lessons learned as identified from three case studies of technology transfers from Saab, a Swedish aircraft manufacturing company to South Africa, the Czech Republic, and India.

    FindingsThe capability gap between sender and receiver has to be dealt with on two levels: on an organizational level; and on an individual level. It is proposed that the disseminative capacity constitutes the ability to assess the capability gap between the sender and receiver, and to convert this assessment to adaptations of the product and production process to include in an industrialization process. On the individual level, the capability-raising activities were connected to employees’ knowledge, Personal Development Plans for the transfer of explicit knowledge, as well as on-the-job training to facilitate the exchange of tacit knowledge.

    Research limitations The research is based on case studies from one company.

    Originality/value – The paper focuses on the context of offset and reports on actual experiences from a capability perspective of technology transfers within the aircraft manufacturing area. It proposes a structured way of identifying and bridging the capability gap within such transfers.

    International transfer of aircraft production: Problems and effects due to cultural differences2011Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In transfer of advanced industrial production in connection with offset business may not the selling organization be free to choose the most suitable subcontractor with respect to culture, organization, technical level etc. This paper discusses in specific Aeronautics (one of five business areas at Saab Group) and identifies different complications that can occur when different cultures meet during the transfer of production processes. The research is based on a case study utilizing interviews, observations and literature studies. Compilation and analysis of gathered empirical data indicates that many of the differences that emerge during transfer of production technology from Aeronautics to subcontractors in other countries can be exemplified by: -differences in hierarchal organization between different cultures, Swedes’ consensus behaviour and avoidance of conflicts and differences in individual motivation factors between cultures. All of these are considered from the perspective of different categories of employees such as; operators, engineers and management. For a successful transfer of production, the case study implies that important factors are; harmonization of production documentation between receiver and sender, and education of project team on receiving company’s culture before the production transfer is started.

    Production Start-up Phase: A Comparison between New Product Development and Production Relocation2012Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    A challenging situation due to a more global market is the increasing need for production relocation. New product development with constant increasing competition challenges the ways to perform production start-up and production relocation. Product development processes focus in general on function of the product and to avoid product quality problems. Production relocation processes also focus on avoiding product quality problems, but problems that occur within production relocation are mostly related to forgotten or misunderstood information. In this paper, a literature review is performed investigating these three areas and relate them to industrial experience. Existing relocation processes are often based on processes for product development. There are several similarities between the production start-up in product development and product relocation since the same result is requested. However, the way to achieve the results can differ within the literature, within the paper are the differences and similarities discussed.

Denna produktionsenhet tillverkar hytterna till Scanias lastbilar på europamarknaden, från plåtrulle till färdigmålad hyttkaross. Produktionsenheten MB består av en pressverkstad, en karossverkstad och ett måleri.

    Uppgiften i detta arbete är att utveckla ett antal mätetal för prestationsmätning av MB:s internlogistik, och utifrån dessa ge förslag på förbättringsmöjligheter i verksamheten.

    Uppgiften löses genom att använda Bourne och Neelys metoder för utveckling av mätetal, så som en framgångskarta för den kritiska framgångsfaktorn effektiv logistik och utformandet av ett definitionsblad, vilket explicit definierar varje mätetal. Detta tillsammans med Parmenters definitioner angående mätetal och arbetssätt vad det gäller prestationsmätning, avser att spegla moderna tillvägagångssätt för prestationsmätning och för implementering av dessa i ett företag.

    De mätetal som rekommenderas för implementering i MB:s logistiska verksamhet är trucktimmar per hytt, leveranspålitlighet, lageryta, energianvändning per hytt för transporter och materialhanteringskostnad per hytt. Flera förbättringsförslag rekommenderas också vad det gäller den förbättringspotential som finns vid införandet av en gemensam materialhanteringsfunktion på MB. Vidare ges också förslag på system- och rutinförändringar som kan genomföras för att ge mer tillförlitlig information för prestationsmätning och skapa mer effektiv logistik.

    Decision making in inter‐corporate projects: A qualitative and quantitative study of project workers in automobile research and pre‐ development projects in Japan and Germany2009Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    This thesis is dealing with the integration of Japanese and German project workers in automobile inter‐corporate research/pre‐development projects. The focus is on better understanding the respective decision making process. As cultural differences play a big role in the way that people behave an extra focus was put on investigating this. The methods chosen for this study were quantitative research in the form of a questionnaire and qualitative research in the form of an interview series.

    For the quantitative research, literature in the cross‐cultural field was studied and from different cultural dimensions suggested by various authors, a synthesis was derived. This was then used as the base for a questionnaire. The data both enabled a quantitative research study and supported the qualitative study. A number of questions with a more straightforward approach to decision making in projects were also a part of the questionnaire. The data was processed using the statistical software SPSS and the results were analyzed using factor analysis and ANOVA.

    The factor analysis of the quantitative data had only one factor which had a significant difference between the German and the Japanese sample. The dimension was called individuality reward and describes to which degree a society reward competent group behavior versus competent individual behavior. The German sample showed a strong tendency towards favoring competent individual behavior whereas the Japanese sample leaned towards favoring competent group behavior.

    The questionnaire questions directly linked to decision making showed no significant differences between the samples showing that individual attitudes within the German and Japanese sample varies more than the cultural differences between the two groups. This shows that you cannot expect a Japanese or German person to act in a certain way in a certain decision making situation just judging on their cultural background.

    In order to get a deep understanding of the decision making process a qualitative series of interviews were conducted. All interviews with Japanese and other people on location in Japan were conducted in‐person at different locations around the Tokyo area. Interviews with people situated in Europe were made over the phone. The interviews were recorded and later transcribed and interpreted to gain a thorough understanding of the decision making process.

    From the qualitative material several differences in how German and Japanese people work and make decisions were found. More time is put into sharing information and getting consensus before a decision in Japan than in Germany were discussions and arguing in meetings are more tolerated. The reason for this behavior in Japan is to not lose face and as well as making it possible to make a decision fast once brought up in a meeting. Germans remain more flexible to revisions after a decision has been made because of the shorter preparation phase.

    There is big overlap of members between different inter‐corporate research projects in the automobile industry. Japanese project members tends to be older than their German counterparts which makes them more stable as younger people might disappear from a project as they move up the corporate ladder. In Japan there is a greater emphasis put into after‐work activities compared to Germany where it is seen as beneficial but not as often used as a way to gain a personal relationship.

    The thesis concludes that by relatively small measures common decision making between Japanese and German project workers can become smooth and with few misunderstandings. Introductions to respective cultures as well as keeping an open mindset and non assertive attitude should help avoid some of the worst case scenarios. A kick‐off in the beginning of a project in order to build a personal relationship and trust would surely help the project come off to a good start. Setting common goals for the project and confirming data with people involved in a decision process will facilitate common consensus decision making. Also confirming decisions as simply as paraphrasing what has been said or by informal one‐on‐one discussions in a break or after a meeting can keep misunderstandings due to the language barrier to a minimum.

    Towards a quality management competence framework: Exploring needed competencies in quality management2018Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Background and purpose –Several studies and recent reports address emerging and expanding needs for Quality Management (QM) impacting the professional practices and activities and maybe also the conceptual underpinnings of QM. An integrative approach for QM, facilitating both operational and strategic leverage has been described as becoming increasingly more important. However, few empirical studies have focused on what QM professionals actually do with even fewer studies focusing on what it actually takes to do QM-work, i.e. the competencies of QM.

    The purpose of this paper is thus to extend the conceptual understanding of QM by introducing an activity and practice-based terminology for describing competencies of QM work in contemporary Swedish organisations and to create a conceptual competence framework suited for successful QM.

    Design/methodology/approach –This paper is based on a cross-case qualitative study design incorporating four Swedish large size organizations where designated QM professionals (n= 34) were targeted, selected and interviewed.

    Findings –Four generic QM roles are posited: centralised & strategic, centralised & operational, decentralised & strategic and decentralised & operational roles. A QM competence framework incorporating four essential QM competence dimensions is presented: the human, the contextual, the methods & process and the development competence dimensions. Competencies are discussed in relation to the “production dilemma” of QM and the emerging need of more integrative and business excellence-oriented QM.

    Fit for purpose? Critical competencies and roles in quality management2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Purpose – The practice of quality management (QM) is transforming and the number, scope and complexity of QM tasks and related QM practices is increasing beyond what could be described as traditional QM. There is currently an ambiguity as to what constitutes a QM professional and the competencies needed to be one. The purpose of this study is to understand if QM professionals are equipped to support contemporary QM work by exploring their competencies, roles and practices in contemporary organizations.

    Design/methodology/approach – The study is based on a survey of QM professionals (n= 249) within eight Swedish large size organizations, surveyed in the fall of 2016 (response rate 81 per cent). The questionnaire covered 7 themes within QM and key results covering competencies and practices were extracted and analysed.

    Findings – The study shows that there is a difference between the levels of perceived formal competencies and levels of informal competencies with the QM professionals in the studied organizations. The most prominent role feature of a QM professional is that of a QM tools and methods specialist. However, though this mainly internally focused role is still in demand, a more strategic and externally focused role is also identified as becoming more in demand.

    Research limitations/implications – The survey data is presented with descriptive statistics. Further studies are needed to extend the results in a more in-depth analysis.

    Practical implications –There is a need for a structured approach in identifying QM competencies and practices for two overall QM roles: QM specialist and QM generalist. Ambitions to create and maintain ambidexterity necessitates both specialist competencies and generalist competencies to balance and harmonize exploitative and explorative organizational capabilities.

    Originality/value This study extends research on the competencies and practices of QM professionals, evaluating the purpose and practices of QM through the experiences of a large number of QM professionals.

    Four facets of learning in performance measurement2018Inngår i: International Journal of Productivity and Performance Management, ISSN 1741-0401, E-ISSN 1758-6658, Vol. 67, nr 9, s. 1608-1624Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose – The purpose of this study is to contribute to a better understanding of the role of learning in performance measurement. Design/methodology/approach – We develop a theoretical framework combining workplace learning theory with purposes of performance measurement. We elaborate this framework empirically by identifying critical incidents from a case set within a context containing a broad range of different performance measurement activities. Finally, we discuss the results and the possible implications for using our theoretical framework in order to better understand facets of learning regarding the design of performance measurement. Findings – Workplace learning theory provides a deeper understanding of how the mechanisms of performance measurements support control or improvement purposes. We propose a tentative framework for learning as a driver for performance measurement and four facets of learning are identified: reproductive, rule-oriented, goal-oriented and creative learning. Research limitations/implications – The empirical material is limited to the healthcare context and further studies are needed in order to validate the findings in other settings. Practical implications – We argue that all managers must consider what kind of learning environment and what kind of learning outcomes best serve the interests of their organisation. Purposeful and carefully designed organisational arrangements and learning environments are more likely to induce intended learning outcomes. Originality/value –Previous connections between the fields of ‘performance measurement’ and ‘workplace learning’ often lack any deeper conceptualisations or problematisations of the concept of learning. In this paper, we provide a more nuanced discussion about the process of learning in performance measurement, which may provide a basis for further research and scholarly attention.

    Performance measurement as a driver for learning and improvement in organizations2016Inngår i: 23rd EurOMA Conference, Trondheim, June 17-22, 2016, Trondheim: NTNU, Department of Production and Quality Engineering and the Department of Industrial Economics and Technology Management , 2016, s. 117-117, artikkel-id PMM-5-2Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The purpose of this study is to contribute to better understanding about levels of learning found in the practices of performance measurement. We create a conceptual model merging established workplace learning theory with operations management purposes of performance measurement. By integrating discretion and organizational logics we interconnect purposes of either control or improvement with four levels of workplace learning: Reproductive, rule-oriented, goal-oriented and creative learning. We empirically elaborate our model using case related critical incidents involving performance measurements. The findings suggest that a conceptual understanding of workplace learning theory meliorates the design and practice of performance measurements for improvement purposes.

    Development of Robust Automated Handling of pre-impregnated Carbon Fibre2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Prepreg is a fibre reinforced polymer composite material often used by the aeronautical industry. The material supplier has pre-impregnated the fibre often with an epoxy resin and cured it to a semi-viscous B-stage where the material is tacky (adhesive). Manual layup of prepreg components is still common because there are only a few automated layup techniques which has limited geometric capability and high investment cost.

    Swerea SICOMP is a research institute which have in collaboration with partners developed a manufacturing demonstrator for automated layup of carbon fibre prepreg components based on robotic handling. The manufacturing demonstrator is able to; feed out prepreg from a spool onto a cutting table, cut the prepreg into plies, pick the plies from the cutting table and place them on a layup table, consolidate the prepreg plies on the layup table and remove the backing paper that covers one side of the prepreg.

    Three robustness problems has been identified and these forms the bulk of this master’s thesis. The first problem is that the robot is unable to place the plies on the cutting table with sufficient accuracy due to fluctuating position of the prepreg on the cutting table. The second problem is that the end effector used for the pick and place operation sometimes fails to pick the adhesive plies from the cutting table. The problem originates in limited holding force by the end effectors suction cups and limited capability to perform a peeling motion when picking due to the design of the end effector. The third problem is that process variables like temperature is believed to effect the robustness of the demonstrator but has not been further studied.

    The first problem was solved by implementing a probing routine which measures the position of the prepreg on the cutting table with an array sensor mounted to the robot. The measurement values are used to reprogram subsequent operations.

    The second problem seems to be solved by designing and implementing a new pick and place end effector. The new end effector has higher holding force and better capability to perform a peeling motion while picking and placing the tacky prepreg plies. Tests with the new end effector has been promising, the pick and placeoperation performs robustly, but all ply geometries was not tested and some minor adjustment is needed to further improve the placing accuracy.

    The third problem has not been solved but studied. A literature study reviled that temperature, relative humidity and prepreg out of freezer age is likely to effect the prepreg adhesive properties which in turn is known to effect the robustness. A test procedure has been devised to test how these variables effect the robustnessof the demonstrator. The tests should be conducted when all process steps in the demonstrator is up and running.

    Unintended Circularity? Assessing a Product-Service System for its Potential Contribution to a Circular Economy2019Inngår i: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 11, nr 10, artikkel-id 2725Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Product-service systems (PSSs) are seen as valuable facilitators of a circular economy (CE) on a business level. However, that PSSs contribute to a CE is not a given and is determined by the chosen PSS business model and strategy applied throughout the entire lifecycle. Thus, in order to support companies in implementing circular business models such as PSSs, an increasing number of frameworks and methods have been proposed in prior research. This article hypothesizes that many industrial companies are expanding to become PSS providers with neither such support nor a strong sustainability focus. There is a gap in the literature regarding the potential contribution of such PSSs to a CE. Thus, the research reported aims to provide initial insight regarding whether unintended circularity, i.e., an unintended contribution to a CE, may occur when becoming a PSS provider. Applying and adapting an existing framework for the assessment of PSSs potential contribution to a CE, the use-oriented PSS of an industrial company was assessed in-depth. Results regarding the relative resource reduction and the prospect of achieving absolute resource decoupling are reported and discussed. While relative improvements over product sales are identified, e.g., resulting from end-of-life efforts on reuse and remanufacturing, opportunities for additional enhancement are found, e.g., in adjustments of the PSS design process. Concerning absolute resource decoupling, a fundamental challenge lies in the use-oriented PSSs dependency on an increasing number of physical components as the companys business expands. This article advances the discussion on PSSs potential contributions to a CE with an in-depth empirical study. For practitioners, the results reported expand on important aspects of efficient and effective PSS provision throughout the lifecycle.

    System- and actor-level challenges for diffusion of renewable electricity technologies: an international comparison2016Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 128, nr SI, s. 105-115Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Abstract It has become increasingly clear that a transition to low-carbon energy systems, including a widespread diffusion of renewable energy technologies (RETs), is necessary for the world to handle the challenges of climate change. Previous innovation system oriented research has identified barriers to development and early-stage diffusion of RETs, but more research is needed to understand what kind of institutional frameworks and governance tools are needed to achieve effective large-scale diffusion at a stage when technologies are commercially available and new demand-side actors become involved. The purpose of this paper is, therefore, to identify the main challenges faced by adopters of renewable electricity technologies under different institutional frameworks as well as their strategies for overcoming them. Results based on a qualitative multiple case study of 28 adopters in France and in Sweden show that adopters were faced with system-level challenges, such as market-structure obstacles and lack of institutional routines, as well as actor-level challenges, such as lack of resources or behavioral characteristics. The study also highlights the difference between blocking and restraining challenges and proposes that barriers are better thought of as challenges that can be overcome. It shows the importance for policy makers to consider not only system-level diffusion challenges, but also to understand actor-level contexts, including the behaviors of adopters who contribute to the transition. A further understanding how new entrants have managed to overcome existing challenges may provide new policy tools to facilitate the adoption for new adopters, for instance by encouraging the use of networks or by supplying specific information to potential adopters who lack it.

    The impact of systemic factors on the deployment of cooperative projects within renewable electricity production - An international comparison2016Inngår i: Renewable and sustainable energy reviews, ISSN 1364-0321, Vol. 65, s. 478-488Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    While cooperative organizations created with the aim to initiate, develop, and operate renewable electricity (RE) projects have received attention for their roles in the transition to a sustainable energy system, the disparities in the number of RE cooperative projects among countries suggest that institutional contexts may have an impact on their deployment. In order to systematically identify the systemic factors that impact their deployment, we use an established framework, considering the strengths and weaknesses in market structure, infrastructures, institutions, interactions, and capabilities. We compare the deployment context in Germany, France, and Sweden in order to understand which systemic factors have an impact and how they affect RE cooperative projects. Based on a review of the literature and qualitative interviews with experts in RE cooperatives, it appears that, although RE cooperative projects share some obstacles with most new entrants of RE, they are particularly exposed to a lack of financial insfrastructure, a lack of knowledge and interactions, and problems related to a lack of regulatory frameworks facilitating their deployment. Results also show that systemic factors are complementary and dependent on each other; lowering one barrier lowers other barriers, and some obstacles strengthen other obstacles. Drawing on the comparison among Germany, France, and Sweden, we highlight some interesting practices that could be used in the coordination and alignment of systemic conditions for the deployment of RE cooperative projects.

    Approaches to Product Variety Management Assuming Configuration Conflict Problem2015Inngår i: FME Transactions, ISSN 1451-2092, Vol. 43, nr 4, s. 271-277Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Complexity problems in mass customized manufacturing are frequently discussed and analysed in order to find suitable methods to optimize extent of product varietes. Moreover, product designers have to consider also constraint satisfaction problem, since some serious conflicts may occur when requirements of the customer are specified based on a wide portfolio of modules or components and given configurations cannot be found. The main scope of this paper is to explore the possibilities of using axiomatic design theory and entropy based measures for quantifying product variety induced complexity. For this purpose, two approaches will be applied on a real case. Then a comparison and analysis of obtained results are included. Computational experiments showed that proposed approaches offer comparable results and can be effectively used to quantify varietyinduced complexity in terms of mass-customized manufacturing.

    A production-transferprocedure based on risk management principles2018Inngår i: Journal of Global Operations and Strategic Sourcing, ISSN 2398-5364Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose –This paper develops a procedure for preparing production transfers based on risk management principles. The procedure should help companies reduce the amount of supply disruptions during transfers and achieve their outsourcing/offshoring objectives.

    Design/methodology/approach – The procedure was developed during a 3-year Design Science study. First, a literature review and case studies were conducted to frame the research problem. Second, a preliminary procedure was developed based on preventive actions from the production transfer literature. Third, the procedure was implemented during an electronics-offshoring case and refined during workshops with the sender and receiver’s transfer-personnel. Fourth, during a seminar, transfer experts verified the procedure by applying it to outsourcing/offshoring cases with which they had experience.

    Findings – Most of the preventive actions were evaluated as relevant for the transfers the procedure was applied to, regardless of industry and relocation type. Nevertheless, the electronics-offshoring case showed that the amount of resources the transfer parties were willing to invest in interactive actions (e.g. cross-locational transfer of personnel) depended on the transfer’s risk level and profit impact. This paper provides propositions about how to better allocate personnel during relocations and enhances the production transfer literature by clarifying transfer-risk management.

    Practical implications – The procedure can be used during the production-transfer phase as a preparation procedure. Moreover, it informs the decision-making process during the relocation-decision and supplier-selection phases.

    Originality/value – To the authors’ knowledge, this is the first production-transfer-preparation procedure based on risk management principles.

    Ytrengöring av alfa-diamond: En studie och urval av ytrengöringsmetoder för hårda beläggningar2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Examensarbetets mål är att rengöra en diamantkomposit med en ytrengöringsmetod. Metoden skulle vara mera effektiv än den manuella sandblästring som används idag för att ytrengöra detaljen.

    Detaljen är liten och har ett vitalt spår som ska rengöras. Detta ställer höga krav på effektiva metoder. De metoder som tas upp teoretiskt i examensarbetet är bland annat blästring, trumling och laserrengöring. Ett urval av metoderna testades. Den metod som utmärkte sig främst I testerna var automatisksandblästring. Det gav lika bra resultat som manuell sandblästring men på en bråkdel av tiden som det tog för manuellsandblästring. Det gjordes även en investeringsberäkning i examensarbetet och den gav att trumling var den billigaste metoden.

    Slutsatsen är att automatisk sandblästring bör användas som metod. Metoden gav ett bättre resultat än övriga metoder och var mindre arbetskrävande än manuell sandblästring.

    Knowledge-Based Integrated Aircraft Design: An Applied Approach from Design to Concept Demonstration2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The design and development of new aircraft are becoming increasingly expensive and timeconsuming. To assist the design process in reducing the development cost, time, and late design changes, the conceptual design needs enhancement using new tools and methods. Integration of several disciplines in the conceptual design as one entity enables to keep the design process intact at every step and obtain a high understanding of the aircraft concepts at early stages.

    This thesis presents a Knowledge-Based Engineering (KBE) approach and integration of several disciplines in a holistic approach for use in aircraft conceptual design. KBE allows the reuse of obtained aircrafts’ data, information, and knowledge to gain more awareness and a better understanding of the concept under consideration at early stages of design. For this purpose, Knowledge-Based (KB) methodologies are investigated for enhanced geometrical representation and enable variable fidelity tools and Multidisciplinary Design Optimization (MDO). The geometry parameterization techniques are qualitative approaches that produce quantitative results in terms of both robustness and flexibility of the design parameterization. The information/parameters from all tools/disciplines and the design intent of the generated concepts are saved and shared via a central database.

    The integrated framework facilitates multi-fidelity analysis, combining low-fidelity models with high-fidelity models for a quick estimation, enabling a rapid analysis and enhancing the time for a MDO process. The geometry is further propagated to other disciplines [Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA)] for analysis. This is possible with an automated streamlined process (for CFD, FEM, system simulation) to analyze and increase knowledge early in the design process. Several processes were studied to streamline the geometry for CFD. Two working practices, one for parametric geometry and another for KB geometry are presented for automatic mesh generation.

    It is observed that analytical methods provide quicker weight estimation of the design and when coupled with KBE provide a better understanding. Integration of 1-D and 3-D models offers the best of both models: faster simulation, and superior geometrical representation. To validate both the framework and concepts generated from the tools, they are implemented in academia in several courses at Linköping University and in industry

Although there is no necessity for a CAD model from the very beginning of the design process, it can be an added advantage to have the model to get the impression and appearance. Furthermore, this means that a seamless transition into preliminary design is achieved since the CAD model can guardedly be made more detailed. For this purpose, knowledge-based aircraft conceptual design applications Tango (Matlab) and RAPID (CATIA) are being developed at Linköping University. Based on a parametric data definition in XML, this approach allows for a full 3D CAD integration. The one-database approach, also explored by many research organizations, enables the flexible and efficient integration of the different multidisciplinary processes during the whole conceptual design phase. This paper describes the knowledge-based design automated methodology of RAPID, data processing between RAPID and Tango and its application in the courses ‘‘Aircraft conceptual design’’ and ‘‘Aircraft project course’’ at Linköping University. A multifaceted user interface is developed to assist the whole design process."

    A new fighter aircraft will most likely be acollaborative project. In this study conceptualknowledge-based design is demonstrated, usingmodels of comparable fidelity for sizing, geometrydesign, aerodynamic analysis and system simulationfor aircraft conceptual design. A newgeneration fighter is likely to involve advancedcontrol concept where an assessment of feasibilitythrough simulation is needed already atthe conceptual stage. This co-design leads to adeeper understanding of the trade-offs involved.In this paper a study for a future combat aircraftis made. Conceptual knowledge-based design isdemonstrated by optimizing for a design mission,including a super-cruise segment.

This enhances the performance of the multidisciplinary design optimization process and allows a more flexible and robust design. The considered disciplines are computer-aided design, computational fluid dynamics, finite element analysis, and dynamic simulation. A high-fidelity geometry created in a computer-aided design environment is computer-aided design centric approach and later used in computational fluid dynamics, finite element analysis for a better understanding of the product as it leads to precise outcomes. The proposed approach is implemented for the conceptual design of a novel product, a tidal power plant developed by Minesto AB using a multidisciplinary design optimization process.

    Toward Consolidation on Product/Service-Systems Design2010Inngår i: Proceedings of the 2nd CIRP IPS2 Conference 2010 / [ed] Sakao, T., Larsson, T., Lindahl, M., Linköping: Linköping University Electronic Press, 2010, s. 219-225Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Research on Product-Service Systems (PSS) has been carried out for many years and in various disciplines. Nevertheless, design guidelines and standards for industrial application are hardly available. Even a standardized terminology has not yet been developed. Consolidation of PSS approaches among research projects and industrial branches is rudimentary. This is an obstacle for companies to incorporate and deploy PSS design approaches and to introduce efficient work or communication processes with customers and suppliers. Meanwhile, standardization on PSS design is “moving into” research agendas. This paper is based on literature analysis, experience in industrially applied research, and standardization practice of the authors. The contribution elaborates on various viewpoints and frequently raised issues in PSS research, which are important in order to consolidate PSS design approaches.

    3D Layout Scanning for Smart Manufacturing: Method Development and a Study of Future Possibilities2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The term ‘Industry 4.0’ leads to many new possibilities like smart factory which is the amalgamation of manufacturing systems in a network to perform tasks more efficiently. It is becoming more and more important for the companies to develop smart factories and integrate the devices within such a facility to meet the demands of the evolving market. The next generation production systems are designed to share the data within the network, plan, and predict the solution for the future problems.

    One such technology under smart factory is 3D laser scanning resulting in point cloud of the production unit. The traditional way of documenting a layout is usually with the help of 2D computer aided designs which are susceptible to measurement errors and changes that are not updated regularly. With the help of point clouds, an as-is representation of the factories can be recorded which can be easily updated with changes in the real world. With advancements in virtual manufacturing, the need for visualization of the factories is increasing drastically. 3D Laser Scanning is one of the better ways of meeting this need, among many other applications.

    The focus of the thesis had been to create a method document for 3D laser scanning of factories and to discuss the future possibilities of it. The research approach used in this thesis was conducting observational study, interviews and testing of the method. One such future possibility is autonomous scanning and how it would be beneficial for a company like Scania which is developing smart factories. Based on the study carried out during the thesis, a document presenting the method developed is included in the report. The report also points out the applications and benefits of point cloud over traditional layout planning methods.

    Prospection of Methods to Support Design and Configuration of Self-Organizing Mechatronic Systems2013Inngår i: Proceedings 2013 IEEE International Conference on Systems, Man, and Cybernetics SMC2013, IEEE , 2013, s. 3854-3861Konferansepaper (Fagfellevurdert)
    Abstract [en]

    There is a substantial difference between traditional industrial systems and systems resultant from emerging production paradigms in terms of both conceptualization and implementation. Backwards compatibility is fundamental in assessing the potential transitional period whereby legacy technology will operate under the conceptual framework of modern approaches. However, before this point can be reached it is necessary to further investigate, assess and quantify the behavior of modern approaches that increasingly rely in self-organization. This article's goal is to give an overview of the behavioral assessment problematic, in the context of self-organizing mechatronic systems, and provide a discussion on opportunities to explore rule-extraction techniques to better understand the influence of design and configuration on the overall system behavior. Although the discussion widely applies to almost all emerging production paradigms the Evolvable Production System paradigm is used as case to bring context and clarity to the discussion.

    Data-mining approach to support layout configuration decision-making in Evolvable Production Systems2014Inngår i: Proceedings 2014 IEEE International Conference on Systems, Man, and Cybernetics (SMC) October 5-8, 2014, San Diego, CA, USA, IEEE conference proceedings, 2014, s. 3649-3656Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Computational and communication capabilities are increasingly being used in all devices. In the production context this leads to the generation of massive amounts of data that are rarely proficuously used. More particularly the application of data-mining techniques to infer knowledge from systems’ operation to improve its design decisions remains fairly unexplored. This article presents an approach to extract system design and configuration rules from Evolvable Production Systems. Furthermore it provides the empirical results from two test-cases that support the hypothesis that a simulation-data-mining approach can help reducing the complexity of the work carried by system designers and production managers.

    Exploring reconfiguration alternatives in Self-Organising Evolvable Production Systems through Simulation2014Inngår i: Proceedings 2014 12th IEEE International Conference on Industrial Informatics (INDIN), Central Campus of the Federal University of Rio Grande do SulPorto Alegre, RS, Brazil, 27 - 30 July, 2014, IEEE conference proceedings, 2014, s. 511-518Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Simulation has played an important role alongthe years to predict systems’ behaviour before theirdeployment. In the case of self-organising mechatronic systemssimulation tools can help researchers and practitionersunderstanding the full potential of the solution as well as itsunderlying limitations. Self-organising mechatronic systemshave passed a feasibility study and presented promisingresults. However they are rarely explored in industry in partdue to the lack of methods to support their design andconfiguration and the difficulty to predict the systems’behaviour before their deployment. Given the cost anddevelopment time associated with building self-organisingmechatronic systems this research problem has been left quiteunattended. In this article we present a tool that enables thecreation and simulation of Evolvable Production Systems andtheir self-organising behaviour. The generated operationalresults can posteriorly be used to analyse the suitability ofdifferent design and configuration alternatives for differentproduct types and volumes.

    Upper body ergonomics in virtual reality: An ergonomic assessment of the arms and neck in virtual environments2017Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    In Virtual Reality (VR), the body is often used as input in VR, having a healthy working posture is important for long session in VR. To assess how severe different interaction methods are for the body, user tests was done in VR. 14 people participated and tested six manipulation controls which operate in different ways. Their hands' and neck's position and orientation was measured throughout the test, and from this data characteristic body postures for each control setup was chosen. These were evaluated with RULA. How great the wrist angle is can have an effect on the severity of the posture. Also whether or not the arm is to the side or across the midpoint of the body should be taken into consideration.When accounting for both the hands and neck, one of these have to come outside their comfortable zone if the hands are supposed to be seen by the user in VR.

    Cash Management from a purchasing perspective: A study of the possibilties for Siemens PGI4 to utilize Cash Management in purchasing2007Independent thesis Advanced level (degree of Magister), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Detta arbete är skrivet för inköpsavdelningen på enheten PGI4, representerat på Siemens Industrial Turbomachinery i Finspång (SIT), med målet att reducera kostnader genom ett förbättrat arbete med Cash Management. Då inköpt material utgör en så pass stor del av värdet på slutprodukten, nära 60 procent, inses genast vilket stort inflytande inköpsfunktionen har på företagets totala kostnader. Även om Cash Management ägnas störst fokus hos företag med likviditetsproblem, finns det mycket att vinna genom att arbeta aktivt med konceptet också i goda tider.

    Därmed är syftet med arbetet att; ”analysera möjligheterna för inköpsavdelningen på Siemens PGI4 att utnyttja Cash Management för att reducera de totala kostnaderna”.

    Längs arbetets gång har en totalkostnadsmodell tagits fram för att tydliggöra kostnaderna relaterade till inköp, och därefter har områden specifikt intressanta ur ett Cash Management-perspektiv identifierats. Utgående från dessa områden har undersökts hur dagens verksamhet ser ut på SIT samt hur andra företag hanterar liknande aktiviteter. På så vis har lösningarna tagits fram angående vad inköp på SIT bör arbeta annorlunda med, samt hur de kan nå förbättringar.

    Genom tydligare riktlinjer för standardkontrakt, ekonomistyrning och villkor för transporter och prognostisering kan arbetssätt inom inköp förbättras. Ett utnyttjande av kassarabatter kan ge kostnadsbesparingar motsvarande 1% av köpesumman. Rekommendationer kopplade till orderprocessen och fakturering syftar till att undvika de årliga kostnaderna på 2,4 miljoner SEK och 300 000 SEK för tidiga leveranser respektive räntefakturor. Ett utnyttjande av inköparnas kompetens inom lagerstyrning, kan resultera i sänkningar av lagernivåer genom att styra lager per leverantör.

    Cooperative Engagement to Define and Deliver Client Value in the Construction Industry2012Inngår i: Modelling value: Selected Papers of the 1st International Conference on Value Chain Management / [ed] Jodlbauer, H; Olhager, J; Schonberger, R., Heidelberg, Germany: Physica Verlag, 2012, s. 139-157Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Relations in the construction industry are traditionally of arms-length, and client value is realized by contractual arrangements. Partnering, as a concept of strategic and project alliances, has been suggested to change the adversarial behaviour by moving towards a more cooperative climate. In the consumer market there are recent examples of changes from firm-centric view of value creation to a co-creation view, with intimate interaction between consumer communities and producers to jointly define and deliver value. The case study has an explorative purpose of describing a cooperative contracting engagement of a local Swedish contractor, when engaging in a recent project. The result shows the opportunities of applying the building blocks of improved interactions to reach co-creation of value: dialogue, access, risk-benefit and transparency. The early and interactive involvement of the contractor with the developer and end-user established project objectives valued and favoured by all parties before the procurement. Important capabilities of the contractor included project management, cooperative behaviour and design and calculation, and a strive to have a pleasant and friendly realisation of the project.

    Call centre work: characteristics, physical, and psychosocial exposure, and health related outcomes2005Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Call centres (CCs) are one of the most rapidly growing forms of workplaces in Sweden. The overall aim of this thesis was to describe work characteristics, physical and psychosocial exposures, and health related outcomes, for CC operators in selected CC in Sweden. The purpose was also to study the test-retest reliability and internal consistency of questions, and the inter-rater reliability of observations and measurements in studies of CCs.

    This thesis is based on two projects, where study I was a cohort study and studies II-V were a cross-sectional survey. Fifty-seven CC operators were compared with a reference group of 1459 professional computer users from other occupations, study I, and 1183 operators (848 women and 335 men) (response rate 77%) from 28 CCs were studied in studies II-V . Questionnaires covering organisation and work characteristics, physical and psychosocial exposures, individual characteristics and symptoms during the previous month was used, studies I-V. Structured observations in accordance with an ergonomic checklist were used to assess workstation design during the subject’s ordinary work, study I and II.

    Operators at external CCs spent longer time on customer calls and had less varied tasks. Additional remuneration, call logging and monitoring was more common at external CCs.

    There were deficiencies in workspace, keyboard- and input device placement. External CCs showed somewhat more problems in the work environment compared with the internal CCs. The CC group spent longer continuous time in front of the computer than other professional computer users.

    Emotional and cognitive demands and time pressure were reported considered high. Emotional demands and limited decision latitude were dominating features in CC work.

    A higher proportion of the CC group reported musculoskeletal symptoms compared to other professional computer users. Three out of four operators reported symptoms in the Neck/shoulder or Arm/hand region, with no major differences between internal and external CCs. Comfort of the work environment showed the strongest association with symptoms in the Neck/shoulder or Arm/hand, in both types of CCs. Other exposures associated with symptoms in the Neck/shoulder or Arm/hand in either type of CC were: low complexity of work, long total time of customer calls per day, continuous computer work without a break, high psychological demands, low decision latitude, lack of social support from colleagues and lack of support from a supervisor. The thesis confirms previously suggested associations between unfavourable work characteristics and management, as well as poor physical and psychosocial environment, and musculoskeletal symptoms in computer-interactive tasks. Among operators at internal CCs, symptoms were particularly related to the nature of calls during work, whereas at external CCs critical exposures were the time spent seated with continuous computer work.

    About half of the questions were classified as having fair to good or higher testretest reliability and can be recommended in further analyses. Other questions should be used with care. A majority of the variables on the ergonomic checklist are classified as having fair to good or higher inter-rater reliability.

    Abstract [en]

    Background: The call center industry is one of the most expansive labor market sectors in Sweden today. The purpose of this study was to investigate the working conditions and symptoms among employees at a call center in Sweden.

    Methods: This study represents the cross-sectional baseline survey, which was part of a prospective cohort study. Fifty-seven call center workers were compared with a reference group of 1,459 professional computer users from other occupations. A questionnaire covered physical and psychosocial working conditions and symptoms during the last month. Structured observations in accordance with an ergonomic checklist were used to assess workstation design during the subject's ordinary work.

    Results: The call center group had worked for a shorter time in their present tasks and spent longer continuous time in front of the computer than the reference group. There were deficiencies in workspace, keyboard- and input device placement. The subjects reported poor support from their immediate supervisor, low control and limited opportunities to influence their work. A higher proportion of the call center group reported musculoskeletal symptoms.

    Conclusion: The call center operators were exposed to working conditions that in other studies have indicated an increased risk of developing musculoskeletal disorders. The study also shows that young computer operators in the call center group with a short working career had a higher prevalence of neck- and upper extremity symptoms than older computer workers in other labor market sectors.

    Background. The purpose was to study the test-retest reliability and internal consistency of questions in a questionnaire concerning working conditions and health and the inter-rater reliability of observations and measurements according to an ergonomic checklist.

    Method. Fifty-seven operators participated in a retest questionnaire and 58 operators participated in an inter-observer test.

    Results. The questions had fair to good or higher reliability in 142 of the total of 312. Twenty-seven of the total of 44 variables in the ergonomic checklist were classified as having fair to good or higher reliability.

    Conclusions. About half of the questions had fair to good or higher reliability and can be recommended for further analyses. The majority of variables in the ergonomic checklist were classified as having fair to good or higher reliability. Low reliability does not necessarily indicate that the reliability of the test, per se, is low but may signify that the conditions measured vary over time or that the answers are aggregated in one part of the scale.

    Abstract [en]

    Background. Call centres (CCs) are among the most rapidly growing forms of workplaces in Sweden. The purpose of the study was to describe and compare working conditions between operators at internal and external CC companies and work tasks of different complexity.

    Method. A questionnaire was answered by 1 183 operators, 848 women and 335 men, from 28 different CCs. The questionnaire covered background factors, employment, working hours and remuneration, call logging and monitoring, duties, computer work and workplace design during the previous month.

    Results. Operators at external companies and operators with low-complexity work tasks were younger, more often employed by the hour and worked on a varying roster. They spent longer time on customer calls and had less varied tasks. Additional remuneration, call logging and monitoring were more common at external companies and among operators with low-complexity work tasks.

    Conclusion. The working conditions varied between internal and external CCs. There was also a variation in working conditions between work tasks of different complexity. There were aspects of supervision style and organization of work at CCs, especially at external ones and those with low-complexity tasks that could introduce stress and lack of well being among the staff.

    Abstract [en]

    Objectives: Call centres (CCs) are one of the most rapidly growing types of workplaces in Sweden. The purpose of the study was to assess associations between exposures at CC work and symptoms in the Neck/shoulders and Arm/hand. Comparisons were made between internal and external CCs. An internal CC is a department or separate unit within a larger company with another main core business, while an external CC is a free-standing company.

    Methods: A cross-sectional study of a selected sample of CCs was conducted. A questionnaire, covering characteristics of work and management, physical and psychosocial exposures and symptoms during the last month, was answered by 1183 operators from 28 CCs.

    Results: Three out of four operators reported pain or aches in one or more of the requested body regions, with no major difference between internal and external CC operators. Comfort of the work environment, showed the strongest association with symptoms in the Neck/shoulder and Arm/hand, in both types of CCs. Other exposures associated with symptoms in the Neck/shoulder or Arm/hand in either type of CC were: low complexity of work, long total time of customer calls per day, continuous computer work without a break, high psychological demands, low decision latitude, lack of social support from colleagues and supervisor.

    Conclusions: The study is unique in that there are no previous studies focusing on a large variety of exposures specific to CC work, based on a large number of workers from different types of CCs. The study confirms previously suggested associations between unfavourable work characteristics and management, a poor physical and psychosocial environment, and musculoskeletal symptoms in computer-telephone interactive tasks. The nature of calls during work were related to symptoms of persons working in internal CCs, whereas the time spent seated and continuous computer work were related to symptoms of those in external CCs.

    Sales and operations planning based on a modularized view of supply chains: Supporting process industries and discrete manufacturing industries2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The purpose of this dissertation is to propose a framework for sales and operations planning (S&OP), which is based on a modularized view of supply chains. The framework should support both process industries and discrete manufacturing industries in their quest for performance. S&OP has been highlighted in this framework due to its essential role in integrating different functions within a company and integrating a company with its supply chain partners (referred to as horizontal integration), and linking different planning levels in a company (referred to as vertical integration). As an integrator, S&ÖP influences companies’ performance.

    Originally, S&OP was developed as a generic process but still in line with the requirements of discrete manufacturing industries. The specific requirements of process industries have not been emphasized in this process to the same extent. In order to suggest a modularized S&OP framework for both process industries and  discrete manufacturing  industries, a systematic literature review is performed to understand the specific characteristics of S&OP in process industries. As a result, the importance of continuity/discontinuity of materials and its influence on the required production processes are highlighted. This indicates that the production process in process industries is actually a hybrid of continuous production and discrete production, whereas the discrete manufacturing industries often only deploy discrete production. Continuous production has specific characteristics that would be beneficial to include in the S&OP process; nonetheless, this is in contrast to the view in the literature that considers S&OP a generic process. Generic here means that S&OP is independent of the context in terms of, for example, the industry in which it is implemented. This issue is investigated in this dissertation by identifying the requirements, which can be considered in the S&OP of process industries as add-ons to the generic S&OP. In addition to this, two other concepts addressing the properties of the production process are identified as important in planning and control, including S&OP. One addresses the level of repetitivity of the production process in response to the market demand, and the other concerns the trigger of the production flow. The three concepts are related to three different types of decoupling points and are the basis for a typology developed herein that provides a modularized view of supply chains. The application of the typology to S&OP leads to a modularized S&OP framework applicable to both process industries and discrete manufacturing industries. The modularized view of supply chains has been long emphasized as an effective and efficient way to support companies’ performance and their competitive position. The typology and the S&OP framework are developed through conceptual research methods.

    To study how the modularized S&ÖP framework is related to companies’ performance measures, different performance measures (including sustainable performance measures) at the S&OP level are extracted from the literature. The performance measures are then classified according to the typology, and linked to strategic performance attributes. Aligning performance measures at S&OP levels and strategic performance attributes would help in enhancing companies’ performance. Sustainable performance measures are included in this classification to provide additional support for companies’ performance. Finally, this approach in classification of  performance measures is studied in four case companies, and the empirical performance measures are linked to the companies’ strategic performance attributes and competitive strategies. The results of this empirical study have, to some extent, verified the results from the classification of performance measures based on the literature.

    This dissertation contributes to the development of knowledge in S&OP. First, it identifies three key concepts in planning and control of manufacturing companies. Second, it investigates how S&OP should be tailored to the specific characteristics of companies and their supply chains. The modularized S&OP framework developed in this dissertation is based on the three identified concepts. This framework provides a foundation for fulfilling the supply chains needs by suggesting decision-making processes, planning techniques, and performance measures for different modules. More specifically, this work investigates how S&OP should be designed and implemented in process industries, which has not been extensively studied before. Third, this dissertation shows how S&OP level performance measures can be selected in line with the specific characteristics of supply chains. Finally, by integrating the sustainable performance measures in the S&OP process, this dissertation expands the scope of S&OP and its potential in supporting companies’ performance.

    Abstract [en]

    This paper provides a systematic literature review of Sales and Operations Planning (S&OP) in process industries. The aim is to investigate the present state of S&OP in process industries in comparison to discrete manufacturing industries and to identify the desired future state of the S&OP process based on the specific characteristics of process industries. The findings of this paper show that this issue has not received much attention in the academic world. Hence there is a need for conceptual models with focus on process industries’ specific characteristics. Process industries are actually hybrids of continuous production and discrete production (respectively, upstream and downstream of the discretization point) and the specific characteristics of process industries are related to the continuous production part. Thus, in this paper, the characteristics upstream of the discretization point are investigated and the integration of them in the S&OP process of the process industries is stressed.

    Abstract [en]

    Management of production activities covers a wide range of decisions. In this paper, a modularised approach is suggested that, through configuration, generates a case-specific flow design. The approach is based on identification of decision categories that are generic and fundamental in the flow design, covering both discrete manufacturing industries and process industries. Each decision category identifies a unique property of the flow which changes at a particular point: this is termed a decoupling point. A three-dimensional modularised typology is developed by combining three different decision categories. Cases from the steel industry and the tooling industry are used to illustrate how the typology can be applied. The modularised approach provides a typology for the application of both qualitative and quantitative methods for flow management, including planning, control and performance management.

    Abstract [en]

    This paper suggests a modularized sales and operations planning (S&OP) framework, consisting of content and process. The framework’s content is based on a typology of decoupling points in which the effect of decoupling points on the decision variables in S&OP is studied. The framework’s process takes a step back and addresses the need for a more elaborate design to precede the operational use of S&OP content for different production contexts. The framework supports both process industries (PIs) and discrete manufacturing industries (DIs), and recognizes their specific requirements and reflects them in their S&OP. The differentiating characteristics of PIs and DIs are emphasized through three different decoupling points, namely: discretization decoupling point, control mode decoupling point, and customer order decoupling point. The suggested framework aims to fill the gap in the literature regarding the lack of aggregate planning processes that match the PIs’ specific requirements by reflecting the differentiating characteristics of PIs in S&OP.

    Abstract [en]

    Key performance measures (KPMs) play an important role in the management of supply chains. An important integrator of the supply chain management is Sales and Operations Planning (S&OP) that connects the strategic and operational plans. S&OP usually impacts supply chain performance through the management of resources and customer satisfaction. This paper suggests a new classification for S&OP-related KPMs. The classification follows a typology of decision categories which are based on decoupling points. The typology supports a modularized approach to supply chain design and provides the possibility to select the KPMs according to the decision criteria of each module. The KPMs are further linked to the SCOR performance attributes to provide the link to the companies’ strategic directives and the strategic conflicts which appear in the modules of the typology are discussed. The sustainable KPMs have also been included in order to provide opportunities for improved sustainable performance. The integration of sustainable KPMs helps in creating competitive advantages for companies through development of capabilities which are beneficial but hard to replicate by competitors. The paper ends with an example that illustrates how the classification can be applied to a case company.

    Warning systems design in a glass cockpit environment2008Independent thesis Advanced level (degree of Magister), 20 poäng / 30 hpOppgave
    Abstract [en]

    In Sweden close to 500 people are killed and several thousands severely injured in traffic each year. This is one of the largest health problems for society in both Sweden and the whole world. In the cars of tomorrow will the main instrument panel and the centre console be screen-based instead of the current solution with “iron instruments” and other physical devices. This future driver environment opens for a flexible and situation-dependent usage of presentation resources. The purpose of this thesis is to explore these possibilities from a warning system perspective.

    The project had its main focus on designing warning system concepts using the HUD and vibrotactile information in a coordinated way based on established HMI principles. Another goal for this thesis work was to generate a functional concept for demonstration and evaluation in the virtual reality lab at the University of Linköping.

    The method of realization was divided into three phases – information gathering, concept generation and implementation. These phases are commonly used in design projects. This way of work supplies structure to the project and makes it possible to achieve an iterative design process.

    The information gathering involved a thorough theoretical study of HMI, interface design and warning design. A state of the art investigation was then conducted to find out how the warning systems, relevant to this thesis, are presented today.

    The concept generation was divided into two parts – warning system design and visual design. The Warning system design concepts were based on different combinations from a morphologic matrix and relevant theory. Consideration was also taken to when the systems are likely to be activated and which modality, or modalities, that then was suitable to use. The visual design concepts were developed by using creative product development methods and the iterative Simulator-Based Design (SBD) theory.

    After concluding the concept generation was the visual design results given functionality by programming software. The visual warning system were then integrated in the simulator software and fully implemented in the simulator cockpit at the university.

    The implemented warning systems were then evaluated by a pilot study conducted in the simulator. Test persons were invited to the VR-lab and given an introduction to the warning systems. They were then asked to drive a predetermined route with a number of different warning system conditions. These test results were later statistically analyzed and evaluated.

    Manufacturing competencies in high-tech NPD: on the impact of vertical integration and coordination2011Inngår i: International Journal of Manufacturing Technology and Management (IJMTM), ISSN 1368-2148, E-ISSN 1741-5195, Vol. 22, nr 3, s. 278-300Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Starting from a distinction between internalisation and outsourcing of manufacturing, this paper studies how the degree of vertical integration affects R&D-manufacturing coordination. The case study findings illustrates that there are several quasi-stages of outsourcing that affect R&Dmanufacturing coordination and manufacturing competence within R&D organisations. For effective R&D-manufacturing coordination to take place, it seems necessary that the R&D department possesses certain manufacturing competencies, both in terms of understanding the constraints of the manufacturing equipment/process and in terms of understanding the relation between production volumes and manufacturing cost. The implication is that managers need to carefully consider the effects of make-or-buy decisions on R&D-manufacturing coordination.

    Preserving the link between RandD and manufacturing: Exploring challenges related to vertical integration and product/process newness2009Inngår i: Journal of Purchasing and Supply Management, ISSN 1478-4092, E-ISSN 1873-6505, Vol. 15, nr 2, s. 79-88Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Adopting a contingency framework, this paper explores consequences of manufacturing outsourcing and product/process newness for RandD-manufacturing coordination. Based on case-study findings, the following coordination challenges are outlined: accessing manufacturing competence and understanding suppliers processes (outsourcing of manufacturing and high newness); receiving feedback from suppliers and motivating suppliers (outsourcing and low-medium newness); exploiting manufacturing competence and establishing close working relations (internalization of manufacturing and high newness); early involvement of manufacturing and suppliers, and reducing variability in supplier performance (internalization and low-medium newness). The paper further elaborates on how the role of purchasing may change in order to address these challenges.

    Competition on a local market: a historical study of market gardens in Stockholm2016Inngår i: XVIII INTERNATIONAL SYMPOSIUM ON HORTICULTURAL ECONOMICS AND MANAGEMENT / [ed] L. Ekelund Axelson, F. Fernqvist, 2016, Vol. 1, s. 135-140Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the period 1880-1930, the interest in gardening products rose substantially on the Swedish market. Import of horticultural produce as well as domestic production increased 20 times. The competition on the horticultural market significantly increased from the 1930s. The costs of fuel and labor rose, and imports took a larger share of the Swedish market as the century progressed, except during the wars. Competition was stiff from countries with lower production costs. After World War II, a series of measures were introduced to stabilize the world economy and kick-start trade. These included the first General Agreement on Tariffs and Trade (GATT), intended to boost international trade by reducing customs duties and trade quotas. At the negotiating table Sweden was particularly anxious about the export opportunities for major industries. This meant easing imports for some products for the sake of the balance of trade, and one category sacrificed was horticultural products. This became a backlash for the market gardens, and the number of companies decreased or the production rationalized and specialized. But there are examples of small-scale family businesses that survived competition from largescale, modern companies in southern Sweden, and increasing imports and rising costs of fuel and labor. These businesses adapted their production to the demands on local markets. Two of these have provided case studies: Nilsson's market garden on Runmarö in the Stockholm archipelago, founded in 1929, and Nora market garden in Danderyd, founded in 1938 and run by the Welander family. Nilsson had a focused strategy, providing a custom range of products to wealthy summer visitors in the Stockholm archipelago. Welander had a differentiated approach, selling products of superior quality, with customers including a delicatessen in Stockholm.

    Abstract [en]

    The links between market gardens and cities were symbiotic until the mid-1900s. In my thesis about market gardens in Sweden 1900-1950, four market gardens in Stockholm County are investigated, trying to find out how different resources and strategies contributed to the businesses competitiveness. Two of the market gardens belonged to mansions with all the staff employed. The other two were established as family businesses by entrepreneurs without employees. Garden products are sensitive to bumps, heat, low temperatures, etc. Due to this, the access to a nearby market was necessary at that time. The development of the trade with garden products was linked to a fast-growing population in the cities, the growing demand for garden products, and the development of the transport sector. From the growing city, gardeners bought horse manure, garbage, or anything that produced heat to the hotbeds when it decomposed. Most of the market gardens were small family businesses situated on small plots. In the 1930s and 1940s in 75% of the businesses a maximum of three people were engaged. The production was both resource-demanding and labour-intensive. The use of hotbeds and greenhouses extended the growing season and made it possible to grow all year around. The gardenerRSQUOs dependence on merchandises increased like an avalanche to beat the growing competition on the market. The import, often of high quality products, was growing very fast and affected the interest for garden products. It forced the domestic horticulture industry to increase the quality and effectiveness of the production.

    The role of the customer order decoupling point in production and supply chain management2010Inngår i: Computers in Industry, ISSN 0166-3615, Vol. 61, nr 9, s. 863-868Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In order to compete successfully, operations in any type of firm need to be strategically aligned to the market requirements. This concerns both manufacturing and supply chain operations. The customer order decoupling point (CODP) is getting increasing attention as an important input to the design of manufacturing operations as well as supply chains. This paper investigates the impact of the position and role of the CODP on issues of concern for production and supply chain management. The focus is on the design and strategic planning aspects of the supply chain, and the design of manufacturing planning and control systems. The paper proposes a dual design approach for production and supply chain planning systems; one type of system for operations upstream the CODP and another type of system for downstream operations in order to fully support the characteristics and objectives of each respective part of the supply chain.

    Förbättringsåtgärder inom produktion och försörjningskedjor: En jämförelse mellan lager- och kundorderproduktion2010Inngår i: Bättre produktivitet, ISSN 1402-1145, Vol. -, nr 7, s. 12-16Artikkel i tidsskrift (Annet (populærvitenskap, debatt, mm))
    Abstract [sv]

    Tillverkande företag strävar efter att förbättra både interna och externa processer för att förbättra sin konkurrenskraft. Exempel på förbättringsåtgärder är ”lean” produktion, integration längs försörjningskedjan och att reducera antalet leverantörer. Vi studerar hur dessa tre förbättringsåtgärder påverkar verksamhetens resultat. Speciellt studerar vi om det finns skillnader mellan fabriker som tillverkar mot lager och fabriker som tillverkar mot kundorder. Mer specifikt studerar vi dels vad som fokuseras och dels om olika förbättringsåtgärder har olika genomslagskraft för dessa två typer av verksamheter. Vi använder data från 216 Australiensiska tillverkande företag. Av dessa tillverkar 107 fabriker mot kundorder och 109 tillverkar mot lager.

This harmonizes with the overall lean approach, but the assemblyis very time-consuming and some tasks are not ergonomically friendly, such as assembly tasks inside a wingbox. Here, it could be possible to increase automation with the aim to facilitate a shorter assembly time andergonomically improved workplace. This paper will present different assembly cell concepts utilizing differentsafety strategies to achieve human-robot cooperation in an aerospace industry assembly line. These conceptswill be discussed in relation to a case in the aerospace industry. The paper concludes with suggestions forthree conceptual human-robot cooperation layouts. These are based on previous research in the areas ofsafety and human-robot cooperation, in combination with observations from an aerospace assembly line.

    On Safety Solutions in an Assembly HMI-Cell2015Inngår i: SAE Technical Papers, Warrendale, PA, USA: SAE International , 2015, s. Art.nr. 2015-01-2429-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The increased diffusion of cooperation between humans and robotics in manufacturing systems is one of the next things to implement within robotics. Since the computer power gets more and more powerful, the possibilities increase to achieve safer working environment, due to that all safety signals demands fast management of data. This could lead to a possibility to work closer and more direct with a robot, using the robot as a third hand. Within an EU FW7 funded project called LOCOMACHs (Low Cost Manufacturing and Assembly of Composite and Hybrid Structures) there are one study focusing on how to support a future higher TRL-leveled HMI cell (Human Machine Interaction) in an assembly task. The main objective in this paper is to present how different external safety systems could support the whole HMI assembly cell to work properly in an industrial context. The scenario for HMI, in this case, is that an operator enters into the robot working area with the aim to perform an assembly task that need two hands. There are different support systems that could be applied to this assembly application, but every one of these needs to coincide with official standards to be applied in an approved industrial HMI assembly cell. The different safety support systems that are used in this research are light barriers, physical barriers and three-position enabler. These safety support systems are tested in a demonstrator assembly cell using a mock-up wing part. The tests with the selected safety support systems in the physical demonstrator will be compared with a concept that uses cameras to achieve the same degree of safety.

    Flexible automation in the printing industry2012Inngår i: Proceedings of the 5th International Swedish Production Symposium / [ed] Mats Björkman, 2012, s. 45-51Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The printing industry had a turnaround on about 700 billion US dollar in 2008. Althoughthe printing process itself is highly automated, a lot of the handling between process stepsis done manually and these heavy lifts could result in occupational injuries with long timeexposure. Operators for example can lift up to 1-2 tons/hour when moving large stacks ofpaper from a pallet to a jogger table before cutting. For quality reasons it’s important tomake these lifts with correct airing of the paper and without harming the edges or surface,something a human is very adapt in doing. To see if it is possible to do this mechanically,a dual armed robot equipped with grippers was used to lift an air paper stacks inlaboratory experiments. In order to achieve the same high quality as in manual handlingthese experiments tested the grippers, gripper fingers, robot movements and grippositions to find the best parameters for a future automated paper handling cell. The testsshowed that a dual armed robot could lift paper stacks with satisfying airing withoutharming the paper. Also, better gripper fingers were developed for lifting the paper withouttears or surface marks.
