    Interrupted Time Series Versus Statistical Process Control in Quality Improvement Projects2016In: Journal of Nursing Care Quality, ISSN 1057-3631, E-ISSN 1550-5065, Vol. 31, no 1, p. E1-E8Article in journal (Refereed)
    Abstract [en]

    To measure the effect of quality improvement interventions, it is appropriate to use analysis methods that measure data over time. Examples of such methods include statistical process control analysis and interrupted time series with segmented regression analysis. This article compares the use of statistical process control analysis and interrupted time series with segmented regression analysis for evaluating the longitudinal effects of quality improvement interventions, using an example study on an evaluation of a computerized decision support system.

    Organisering för individualitet: transparenta och opaka aspekter i utvecklingsprocesser2002Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The doctoral dissertation 'Organising for individuality - transparent and opaque aspects of development processes' deals with the relationship between a company's ability to develop new products and its ability to change the way it organises its product development activities. The dissertation is based on a real time study of two product development and two organizational change processes at Orrefors Kosta Boda AB.

    The company has a tradition of innovative product development based on a high degree of individuality. In this study, individuality refers to situations where differences between individuals' (i.e. designers') distinctive features are important for a company's success and not to individuals talents or capabilities per se.

    In studying and analysing the product deveopment processes an (opaque) underlying thought structure appears in terms of a tension between 'a separating and a unifying logic of effectiveness'. The two logics of effectiveness constituted underlying assumptions and answers to the question of how to be an innovative and commercially successful company in the high quality glass industry.

    The product development was conducted in an "inescapable" tension of separating and unifying, indicating that the separating and unifying logics of effectiveness should - in the context of product development - be viewed as a 'neccessary relation of incompatibility' rather than mutually exclusive.

    In spite of two attempts to change the organising of the product development in the company, the measures taken did not alter any fundamental conditions of the product development within the company, and therefore not the problems the change initiatives were designed to address.

    In the literature on product development and innovation scholars require research with an approach that links structural conditions to action and interaction. Using Archer's (1995) morphogenetic perspective to relate product development to organizational change, this dissertation is an attempt to do this.

    Kunskapsintegration och innovation i en internationaliserande ekonomi: Slutrapport från ett forskningsprogram2015Collection (editor) (Other academic)
    Abstract [sv]

    Den här skriften presenterar ett urval resultat och texter från forskningsprogrammet ”Kunskapsintegration och innovation i en internationaliserande ekonomi” (Knowledge Integration and Innovation in Transnational Enterprise, KITE) som finansierats av Riksbankens Jubileumsfond i två faser under åren 2007–2015. I programmet har vi analyserat hur företag, speciellt i tekniktunga industrier, påverkas av den allt mer globala konkurrensen om nya produkter och tjänster, hur nya specialiserade kunskaper växer fram och tas tillvara, och hur de kan förenas med existerande kunskapsbas. I denna skrift finns studier på tre olika nivåer: branschnivån, med analyser av innovationsprocesser och kunskapsutmaningar i industriella sektorer; företagsnivån, med skildringar av förändringar i företagens interna organisering av kunskapsbildande processer och undersökningar av nya former för utbyte och samspel mellan företag; samt mikronivån, med undersökningar av samspelet mellan individuella specialister inom företag. Skriften vänder sig både till den intresserade allmänheten och till forskare med annan vetenskaplig bakgrund. Fokus är på internationellt konkurrerande branscher och företag, men analyserna av kunskapens delning och sammanflätning, separation och integration, har bäring också på andra kunskapsintensiva sektorer och verksamheter, från statliga verk till sjukvård.

    En vetenskaplig presentation av programmets forskning under de första fyra åren finns i boken Knowledge Integration and Innovation: Critical Challenges Facing International Technology-Based Firms (redigerad av Berggren, Bergek, Bengtsson, Hobday & Söderlund och utgiven av Oxford University Press 2011). En uppföljande volym, Managing Knowledge Integration Across Boundaries, planeras av samma förlag 2016 (redigerad av Tell, Berggren, Brusoni & Van de Ven). I den medverkar ett antal internationella författare vilket visar kunskapsområdets globala tyngd och intresse. Under programmets drygt åtta år har deltagarna publicerat ett mycket stort antal artiklar, konferensbidrag, bokkapitel och liknande. För dessa hänvisar vi till programmets hemsida www.liu.se/kite.

    Vi har under hela programperioden arbetat intensivt med att diskuteraoch konstruktivt kritisera och utveckla varandras bidrag. Därför har det varit naturligt att denna skrift inbegriper många programdeltagares medverkan. En presentation av samtliga medverkande finns i slutet av denna skrift. Följande KITE-forskare har medverkat i nedan angivna kapitel:

    Hans Andersson (kapitel 4)

    Leveraging inventors' creativity2011Conference paper (Other academic)
    Abstract [en]

    While creativity is often understood as the generation of valuable novelty, we extend that view into a framework based on well-known and established models from the creativity literature. In addition to generation of novelty which forms our frameworks first dimension, we add selection of novelty, and type of creative contribution.  

    Based on interviews with inventors and managers in three large, patent-intensive firms, representing completely different industries, we show how the framework can be employed in order to better understand in what ways different practices exploit and/or support the inventors’ creative abilities. By relating the practices not to creativity in general but to components of creativity (c.f Amabile 1997) the paper enriches the discussion of how inventors’ can be leveraged in technology-based firms.

    Exploring and exploiting inventors at Westco: a case of ambidexterity in R&D2010In: International Journal of Project Organisation and Management, ISSN 1740-2891, E-ISSN 1740-2905, Vol. 2, no 3, p. 254-266Article in journal (Refereed)
    Abstract [en]

    Achieving both exploration and exploitation at the same time has become an increasingly important success factor for both firms and units within firms. Based on a single case study, this paper addresses how R&D units, traditionally regarded as responsible for firms’ explorative activities, work to also increase exploitation in R&D. The results suggest that in a project intensive context such as R&D, the role of project management becomes more important to achieve ambidexterity. It is, however, not an easy task for project managers to take on, and the Westco case provides illustrative examples of both pitfalls and structures designed to help the managers.

    The Role of Patent Engineer - Inventor Interaction for Research and Development Creativity2014Conference paper (Refereed)
    Abstract [en]

    Patents as a strategic tool has been much in focus lately, both in research and in the corporate world. Considering this, there has been surprisingly little interest paid to the process in which patents are generated within firms. Based on interviews with patent engineers and inventors who have been involved in interaction with each other in patenting processes, plus their patent managers, this study describe and discuss the patent drafting process as one (partly) driven by interaction. The patent drafting process is described as a process of asymmetrical collaboration delivering two distinct, but related outcomes – a refined invention and a patent application that most likely is better than it would have been otherwise. These outcomes are not cases of collective creativity as patent engineers do not invent and inventors do not (normally) define patent claims. This does not diminish the importance of the collaboration. Three roles - “opportunity recognizer”,“konstruktiver opponent”, and “enabling bureaucrat” – are identified and used to frame the patent engineers’ work and contributions to creativity.

    Design as change - from teleology to guided evolution?2014In: Proceedings of the 19th DMI: AcademicDesign Management Conference / [ed] Erik Bohemia, Alison Rieple, Jeanne Liedtka, Rachel Cooper, Boston, USA: Design Management Institute , 2014, p. 1948-1971Conference paper (Refereed)
    Abstract [en]

    Design is connected to change. Whether we start from Herbert Simons often cited ’the transformation of existing conditions into preferred ones’ (1996, p.111), or design as linked to innovation, design is a future oriented, change inducing activity. But how is design thinking (in a wide sense) different from traditional managerial thinking in terms of change? This paper explores and identifies change perspectives in design literature, very selectively represented by ‘classic views’, design thinking, and C-K theory. By using Van de Ven and Poole’s (1995) four ‘basic types of process theories that explain how and why change unfolds’; Life Cycle, Dialectics, Teleology, and Evolution, and Pettigrew’s (1987) distinction between process and content of change, we find that design processes are commonly described as similar to an evolutionary process with gradual development (divergence), combined with some characteristics of teleology (convergence), that together constitute the motor(s) of the process. By using Heskett’s (2002) distinction between ‘utility’ and ‘significance’ it is possible to further dissect design processes. Processes aiming for ‘utility’ eventually must converge into a solution, but is it necessarily the same for processes by which ‘significance’ is designed, created and maintained? Further, the uncontrollability and emergence aspects of evolutionary processes are interesting challenges from a managerial viewpoint. A generative way to frame design processes may be to see them as guided evolutionary processes (Lovas and Ghoshal, 2000). ‘Guided’ maintains manageability, while ‘evolutionary’ provides essential variety.

    Design as Change - From Teleology to Guided Evolution?2014Conference paper (Other academic)
    Abstract [en]

    Design is connected to change. Whether we start from Herbert Simon’s often cited “the transformation of existing conditions into preferred ones” (1996 p.111) or design as linked to innovation (Brown 2008, Verganti 2006) or even Heskett’s (2002) ‘betterment of the human condition’, design is a future oriented (Buchanan 2001), change inducing activity. But how is design thinking (in a wide sense) different from traditional managerial thinking in terms of the concept of change? What of the process(es) by which the existing conditions are transformed into the preferred ones, i.e. how may the change process be conceptualized in design? How does the general concern of change in the design community relate to the advances in strategic and organizational change theories? Our aim is to begin an exploration of how design may be conceptualized in relation to change.

    We do this by using two out of Pettigrew’s (1987) three related aspects of change: ‘process’, how something changes, and ‘content’, i.e. what is changed, to frame design as change (the third is ‘context’, the why of change). We make an attempt to explore and identify change perspectives, explicit or implicit, in design by using Van de Ven and Poole’s (1995) synthetic model of four “basic types of process theories” (p. 511): teleology, evolution, life cycle, and dialectic, all driven by different generative mechanisms or ‘motors of change’. Van de Ven & Poole’s ideal process types do though not handle the content aspect. To capture design content, we therefore use Heskett’s (2002) division of the designed artifacts’ function into two concepts, ‘utility’ and ‘significance’.

    Design processes are normally described as either of a teleological kind, i.e. driven by a goal set at the beginning of the process, or as similar to an evolutionary process. Some elements of the evolutionary model are frequent in descriptions of design processes, e.g. iterativity, prototyping and gradual development. However, the uncontrollability and slowness of evolution are less salient. A better way to frame design processes as evolutionary may therefore be to see them as guided (Lovas and Ghoshal 2000), i.e. driven not only by random mutation and competition but also by intent.

    By using Heskett’s distinction between utility and significance it is possible to further dissect the design process/design processes. Processes aiming for ‘utility’ eventually must converge into a solution, but is it necessarily the same when it regards the process by which ‘significance’ is designed, created and maintained? By analytically separating (c.f. Archer 1995) the by definition integrative design process, we argue that discussing design as process and content expands previous views of design as change.

    Knowledge integration of and by industrial design2013Report (Other academic)
    Abstract [en]

    Jan Carlzon, the Scandinavian airline SAS’ CEO during the successful eighties, tells a little story in his recently written comment to the 2008 Swedish re-issue of his 1985 book “Moments of Truth” [Swedish title: “Riv pyramiderna!” (2008)]. Carlzon describes how NOKIA’s CEO in the early 2000’s had told him that they worked like dogs to fill their mobile phones with values people were willing to pay for in order to keep the margins required. A short time later the telecom company Ericsson had its annual shareholder meeting and during the meeting a young girl asked: “Why does not Ericsson make phones that people want?” The chairman ignored the question – according to Carlzon the only relevant question asked – and instead he talked about lowering costs.

    Was there something that Ericsson had not understood at the time? Their phones’ technical functionality was good so why did not people want them? Roughly ten years later we would like to, somewhat simplified, say that Ericsson had not quite understood the need for beauty in their sophisticated high-tech products. They managed to integrate everything apart from a sense of beauty, i.e. the aesthetic and symbolic aspect that made the young girl and others prefer other brands. Even if Ericson had been aware, had they able to integrate beauty and knowledge about “beauty aspects” in their products? No doubt had Ericsson been able to integrate a number of more or less related, complementary technological knowledge bases, but can knowledge about aesthetic and symbolic aspects, what we call “beauty”, be dealt with in the same way?

    The contemporary need for depth of knowledge leads to increasing specialization and subsequently companies’ need for increasingly sophisticated means for integration of knowledge has increased. This is reflected in the field of knowledge integration (KI) which empirically has explored integration of knowledge bases from a rather technical, rationalistic perspective, and outputs of KI processes have in earlier research been framed in terms of efficiency, effectiveness and innovation (Tell, 2011). This is a limitation it shares with strategic management research (Dalpiaz et al 2010). However, we argue that the complexity in today’s products and services may extend beyond what the KI field have hitherto acknowledged.

    A future development of the KI field could be to explore the user perspective on, and role in, the value creation and appropriation system, and to include the aesthetic and symbolic nature of products and services. This paper aims to contribute to the KI field, by exploring some consequences of extending the scope of knowledge integration to include integration of and by Industrial design.

    Industrial design is a practice and a field of knowledge that spans the divide between rationalistic problem-solving and the seeming irrationality of the aesthetic and the socio-cultural (Verganti 2003). Industrial design is interesting in this context both for its content, i.e. as a field of knowledge to be integrated, and because of its process view that may be seen as an approach on how to integrate. This paper thus aims to discuss integration of and by design in order to broaden the dominating technological empirical scope of KI. We will relate integration of and by design to previous understandings of KI as a way to explore the hierarchy of capabilities (Grant 1996a).

    The coming section gives a very brief introduction to KI and its relative neglect of the increasingly important knowledge about what makes people want and desire things apart from their technical functionality or use value. Then follows a section on Design and especially Industrial design where we use Grant’s (1996a) characteristics of KI to discuss how industrial design can contribute to competitive advantage from a KI view. The following section “Integration of and by design” somewhat artificially separates the content of industrial design as a field of knowledge from the view that industrial design may be a leading function pushing the envelope of technological knowledge, and thus a way of integration knowledge(s). Finally there is a discussion summarizing our arguments and findings and proposing how to go on.

    Aircraft Systems Modeling: Model Based Systems Engineering in Avionics Design and Aircraft Simulation2009Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Aircraft developers like other development and manufacturing companies, are experiencing increasing complexity in their products and growing competition in the global market. One way to confront the challenges is to make the development process more efficient and to shorten time to market for new products/variants by using design and development methods based on models. Model Based Systems Engineering (MBSE) is introduced to, in a structured way, support engineers with aids and rules in order to engineer systems in a new way.

    In this thesis, model based strategies for aircraft and avionics development are studied. A background to avionics architectures and in particular Integrated Modular Avionics is described. The integrating discipline Systems Engineering, MBSE and applicable standards are also described. A survey on available and emerging modeling techniques and tools, such as Hosted Simulation, is presented and Modeling Domains are defined in order to analyze the engineering environment with all its vital parts to support an MBSE approach.

    Time and money may be saved by using modeling techniques that enable understanding of the engineering problem, state-of-the-art analysis and team communication, with preserved or increased quality and sense of control. Dynamic simulation is an activity increasingly used in aerospace, for several reasons; to prove the product concept, to validate stated requirements, and to verify the final implementation. Simulation is also used for end-user training, with specialized training simulators, but with the same underlying models. As models grow in complexity, and the set of simulation platforms is expanded, new needs for specification, model building and configuration support arise, which requires a modeling framework to be efficient.

    Abstract [en]

    This paper describes a method and an integrated environment for model based design,simulation and analysis of aircraft flight control systems. Design of flight control systemsinvolves domain knowledge from several different disciplines such as mass & inertia,aerodynamics, hydraulics and electronics which requires a structured method aswell as a powerful environment to succeed in the control system design. The core tool inthis design environment is the model editor SystemBuild which is based on functionalflow block diagrams. The presented method is illustrated using the development of theGripen fighter aircraft flight control system as an example.

    Abstract [en]

    In aircraft development, it is crucial to understand and evaluate behavior, performance, safety and other aspects of the subsystems before and after they are physically available for test. Simulation models are used to gain knowledge in order to make decisions in all development stages. This paper focuses on a special kind of simulation technique called Hosted Simulation, when a model created in one tool is generated to executable code and imported (hosted) in another tool to perform simulation.

    In this paper we report on experience gained from evaluating two different approaches of hosted simulation. Furthermore, the suitability of the two approaches can vary during different phases of aircraft development and utilization, from concept evaluation to end user support. The model of an aircraft subsystem shows that hosted simulation is a powerful and efficient technique.

    Abstract [en]

    Conceptual design for complex products like aircraft and power plants requires a considerable effort since the product models become very large if they are to cover all important aspects for different stakeholders. To cope with this overall effort, designers have to rely on legacy designs and reuse, and improve the product concepts incrementally between product generations.

    This paper describes a generalized inheritance mechanism we call generic object inheritance that enables quick reuse and modification of conceptual product models at any level in their hierarchical break down structures. By facilitating reuse of conceptual models of previously well studied products, more time can be spent on developing the parts that contain the edge of a new product generation. This enables keeping the modified concepts in context of a complete analyzable product model where the impact of changes can be studied without having to maintain multiple copies of the same object structures.

    The paper describes how generic object inheritance is used for developing the next version of a conceptual product model of a small business jet, while reusing the essential parts of the previous version with minor modifications to design parameters and substructures.

    The design and core mechanisms of generic object inheritance are briefly described, and illustrated with examples from the case study.

    Abstract [en]

    In the planning and concept study phases of the next generation Gripen fighter aircraft, methods and tools studies have been performed. Capabilities and limitations of the Simulink toolset have been evaluated to explore how it can support model based systems/software engineering. In this paper, three different approaches of Simulink usage for functional development are presented:

    1. The functional oriented systems modeling and simulation approach where the function is in focus; complete enough to be simulatable, but abstract from an implementation point of view.
    2. An implementation oriented specification approach that is based on a modeling framework with predefined system architecture, scheduling, data types and rules for discretization. The resulting embedded software is hand coded using the model as specification.
    3. Similar to approach two but here the embedded software is automatically generated using a high quality code generator.

    The driver for choosing approach is threefold; high quality, short development time and low cost. Some experiences based on these prerequisites are presented, mainly concerning the aspects of scalability, such as; model architecture, license model and project ramp-up challenges. The results are also compared to the existing SystemBuild based development environment. When introducing high-end engineering practices and tools such as Simulink in an organization developing safety-critical products, it is important to make sure that also basic management practices (e.g. Requirements-, Configuration- and Change Management) are thoroughly handled.

    Abstract [en]

    A Unified Modeling Language/Systems Modeling Language (UML/SysML) subset was the modeling notation selected for an aerospace systems engineering project at Saab Aerosystems. In this paper, the rationale for selecting UML/SysML is given, along with a description of the situation at the project planning stage regarding business conditions, method and tools support. The usage of use case, sequence, and activity diagrams are described as well as definition of functional chains with SysML. Furthermore, the connections to system implementation activities including code generation and simulation are discussed. The advantages and disadvantages of using UML/SysML from experience in an industrial context are reported.

    It is also described how UML/SysML is related to industrial research projects in the Model Based Systems Engineering (MBSE) methods and tools area. Introducing UML/SysML with a methodology and a supporting toolset in an operative organization require a clear strategy, including planning, just-in-time training, and mentor support. Finally, industrial needs for further development of SysML are discussed.

    Abstract [en]

    This paper defines the challenges and needs related to Configuration Management of large scale aeronautical simulation systems, where the MBSE approach is a guiding force. The basic problem is to support modeling and simulation of all variants of a product line. The simulation models may be used in (at least) three different contexts; development, verification and training, each with their specific objectives.

    Assumptions and basic components of the research issue are as follows: There exists a defined product line. The product line is modeled with respect of

    • Configuration; for certification, delivery, and maintenance in a PDM/PLM context
    • Behavior; for development, verification and training in a simulation context

    Configurable simulation models are developed and maintained to represent parts/modules of the product line as well as the environment where the products operate. Each simulation model included in any utilized simulation system can be viewed as a module in a (simulation product) platform. The modular models are stored in a model library for easy access and inclusion in a simulation system. Every model must be configurable in at least three dimensions; representation, usage and implementation. They will represent a specific product within the product family, they will be used in some of the three contexts (development, verification and training) and they will be implemented in a specific simulation platform/architecture.

    Management of configurable simulation models in the described context is an increasingly challenging activity. Supporting systems and methods for configuration and integration of models and simulation systems are not mature and do not scale up. To view the model set as a Software Product Line representing the Product Line of the end products is an approach to more stringent map the simulation models to the real product/system. A concept of a structured ConfiguratioN datA object (CNA-string) is introduced as a means to integrate configuration information and to be used for simulation set-up purposes. Application example in the work is the light weight fighter aircraft Saab 39 Gripen.

    Variability and Customization of Simulator Products: A Product Line Approach in Model Based Systems Engineering2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    AIRCRAFT DEVELOPERS, like other organizations within development and manufacturing, are experiencing increasing complexity in their products and growing competition in the global market. Products are built from increasingly advanced technologies and their mechanical, electronic, and software parts grow in number and become more interconnected. Different approaches are used to manage information and knowledge of products in various stages of their lifecycle.

    "Reuse" and "Model Based Development" are two prominent trends for improving industrial development efficiency. The product line approach is used to reduce the time to create product variants by reusing components. The model based approach provides means to capture knowledge about a system in the early lifecycle stages for usage throughout its entire lifetime. It also enables structured data  management as a basis for analysis, automation, and team collaboration for efficient management of large systems and families of products.

    This work is focused on the combination of methods and techniques within;

    • modeling and simulation-based development, and
    • (re)use of simulation models through the product line concept.

    With increasing computational performance and more efficient techniques/tools for building simulation models, the number of models increases, and their usage ranges from concept evaluation to end-user training. The activities related to model verification and validation contribute to a large part of the overall cost for development and maintenance of simulation models. The studied methodology aims to reduce the number of similar models created by different teams during design, testing, and end-user support of industrial products.

    Results of the work include evaluation of a configurator to customize and integrate simulation models for different types of aircraft simulators that are part of a simulator product family. Furthermore, contribution comprises results where constraints in the primary product family (aircraft) govern the configuration space of the secondary product family (simulators). Evaluation of the proposed methodology was carried out in cooperation with the simulator department for the 39 Gripen fighter aircraft at Saab Aeronautics.

    Support for configuration and instantiation of large-scale aircraft simulations has become a major issue as the numbers of models grow, model fidelity increases and there is a trend to design models to allow reuse between simulation environments. In this work a method for configuration support is presented that is based on the Product Line principles with structures and data inherited from the Product Data Management system. An XML-based information object to carry product configuration data and knowledge between tools, called a CNA-string is introduced. A rule-based method to support specification of consistent configurations is adopted from the sales configuration domain. The application example is configurations of the Gripen fighter aircraft simulation models.

    This paper describes a framework for development and validation of multipurpose simulation models. The presented methodology enables reuse of models in different applications with different purposes. The scope is simulation models representing physical environment, physical aircraft systems or subsystems, avionics equipment, and electronic hardware. The methodology has been developed by a small interdisciplinary team, with experience from Modeling and Simulation (M&S) of vehicle systems as well as development of simulators for verification and training. Special care has been taken to ensure usability of the workflow and method descriptions, mainly by means of 1) a user friendly format, easy to overview and update, 2) keeping the amount of text down, and 3) providing relevant examples, templates, and checklists. A simulation model of the Environmental Control System (ECS) of a military fighter aircraft, the Saab Gripen, is used as an example to guide the reader through the workflow of developing and validating multipurpose simulation models. The methods described in the paper can be used in both military and civil applications, and are not limited to the aircraft industry.

    Abstract [en]

    In development and support of complex products such as power plants, automotive vehicles, or aircrafts, modeling and simulation has become an important activity as a basis for knowledge capture. Simulation is used in several steps of the product lifecycle; for evaluation of early design, for system verification, and for user training. With emerging techniques such as tools for high-level modeling, multi-core computing, and visualization, the number of useful models is growing. This paper focuses on reuse of multipurpose models and configuration support in a product line context. A configurator prototype system is presented. The simulator set created from validated models is considered to be a secondary product line. The product set which the simulation models represent is considered to be the primary product line. The Saab Gripen fighter aircraft, together with simulators in which the aircraft behavior, performance, and handling qualities are represented, is used to exemplify application. Integration principles of the systems for simulator configuration, Software Configuration Management, and Product Data Management (PDM) are studied. Preliminary results show that a configurator tool can be used, but there is need to map structures between the simulation and PDM domains.

    Abstract [en]

    Context: "Reuse" and "Model Based Development" are two prominent trends for improving industrial development efficiency. Product lines are used to reduce the time to create product variants by reusing components. The model based approach provides the opportunity to enhance knowledge capture for a system in the early stages in order to be reused throughout its lifecycle. This paper describes how these two trends are combined to support development and support of a simulator product line for the SAAB 39 Gripen fighter aircraft.

    Objective: The work aims at improving the support (in terms of efficiency and quality) when creating simulation model configurations. The objective is to increase the level of reuse when combining and customizing models for usage in a range of development and training simulators.

    Method: The research has been conducted with an interactive approach using prototyping and demonstrations, and the evaluation is based on an iterative and a retrospective method.

    Results: A product line of simulator models for the SAAB 39 Gripen aircraft has been analyzed and defined in a Product Variant Master. A configurator system has been implemented for creation, integration, and customization of stringent simulator model configurations. The system is currently under incorporation in the standard development process at SAAB Aeronautics.

    Conclusion: The explicit and visual description of products and their variability through a configurator system enables better insights and a common understanding so that collaboration on possible product configurations improves and the potential of software reuse increases. The combination of application fields imposes constraints on how traditional tools and methods may be utilized. Solutions for Design Automation and Knowledge Based Engineering are available, but their application has limitations for Software Product Line engineering and the reuse of simulation models.

    Towards Configuration Support for Collaborative Simulator Development: A Product Line Approach in Model Based Systems Engineering2011In: Proceedings of the 2011 20th IEEE International Workshops on Enabling Technologies, WETICE 2011: Infrastructure for Collaborative Enterprises, IEEE conference proceedings, 2011, p. 185-192Conference paper (Other academic)
    Abstract [en]

    In development and support of complex products such as power plants, automotive vehicles, or aircrafts, modeling and simulation has become an important activity as a basis for knowledge capture. Simulation is used in several steps of the product lifecycle; for evaluation of early design, for system verification, and for user training. With emerging techniques such as tools for high-level modeling, multi-core computing, and visualization, the number of useful models is growing. This paper focuses on reuse of multipurpose models and configuration support in a product line context. A configurator prototype system is presented. The simulator set created from validated models is considered to be a secondary product line. The product set which the simulation models represent is considered to be the primary product line. The Saab Gripen fighter aircraft, together with simulators in which the aircraft behavior, performance, and handling qualities are represented, is used to exemplify application. Integration principles of the systems for simulator configuration, Software Configuration Management, and Product Data Management (PDM) are studied. Preliminary results show that a configurator tool can be used, but there is need to map structures between the simulation and PDM domains.

    Experience from introducing Unified Modeling Language/Systems Modeling Language at Saab Aerosystems2010In: Systems Engineering, ISSN 1098-1241, E-ISSN 1520-6858, Vol. 13, no 4, p. 369-380Article in journal (Refereed)
    Abstract [en]

    A Unified Modeling Language/Systems Modeling Language (UML/SysML) subset was the modeling notation selected for an aerospace systems engineering project at Saab Aerosystems. In this paper, the rationale for selecting UML/SysML is given, along with a description of the situation at the project planning stage regarding business conditions, method and tools support. The usage of use case, sequence, and activity diagrams are described as well as definition of functional chains with SysML. Furthermore, the connections to system implementation activities including code generation and simulation are discussed. The advantages and disadvantages of using UML/SysML from experience in an industrial context are reported.

    It is also described how UML/SysML is related to industrial research projects in the Model Based Systems Engineering (MBSE) methods and tools area. Introducing UML/SysML with a methodology and a supporting toolset in an operative organization require a clear strategy, including planning, just-in-time training, and mentor support. Finally, industrial needs for further development of SysML are discussed.

    Experience from Model and Software Reuse in Aircraft Simulator Product Line Engineering2013In: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 55, no 3, p. 595-606Article in journal (Refereed)
    Abstract [en]

    Context: "Reuse" and "Model Based Development" are two prominent trends for improving industrial development efficiency. Product lines are used to reduce the time to create product variants by reusing components. The model based approach provides the opportunity to enhance knowledge capture for a system in the early stages in order to be reused throughout its lifecycle. This paper describes how these two trends are combined to support development and support of a simulator product line for the SAAB 39 Gripen fighter aircraft.

    Objective: The work aims at improving the support (in terms of efficiency and quality) when creating simulation model configurations. The objective is to increase the level of reuse when combining and customizing models for usage in a range of development and training simulators.

    Method: The research has been conducted with an interactive approach using prototyping and demonstrations, and the evaluation is based on an iterative and a retrospective method.

    Results: A product line of simulator models for the SAAB 39 Gripen aircraft has been analyzed and defined in a Product Variant Master. A configurator system has been implemented for creation, integration, and customization of stringent simulator model configurations. The system is currently under incorporation in the standard development process at SAAB Aeronautics.

    Conclusion: The explicit and visual description of products and their variability through a configurator system enables better insights and a common understanding so that collaboration on possible product configurations improves and the potential of software reuse increases. The combination of application fields imposes constraints on how traditional tools and methods may be utilized. Solutions for Design Automation and Knowledge Based Engineering are available, but their application has limitations for Software Product Line engineering and the reuse of simulation models.

    Configuration Management of Models for Aircraft Simulation2010In: Proceedings of the 27th International Congress of the Aeronautical Sciences, 2010, p. 10-Conference paper (Other academic)
    Abstract [en]

    Support for configuration and instantiation of large-scale aircraft simulations has become a major issue as the numbers of models grow, model fidelity increases and there is a trend to design models to allow reuse between simulation environments. In this work a method for configuration support is presented that is based on the Product Line principles with structures and data inherited from the Product Data Management system. An XML-based information object to carry product configuration data and knowledge between tools, called a CNA-string is introduced. A rule-based method to support specification of consistent configurations is adopted from the sales configuration domain. The application example is configurations of the Gripen fighter aircraft simulation models.

    Method and Integrated Tools for Efficient Design of Aircraft Control Systems2006In: 25th International Congress of the Aeronautical Sciences, 2006Conference paper (Other academic)
    Abstract [en]

    This paper describes a method and an integrated environment for model based design,simulation and analysis of aircraft flight control systems. Design of flight control systemsinvolves domain knowledge from several different disciplines such as mass & inertia,aerodynamics, hydraulics and electronics which requires a structured method aswell as a powerful environment to succeed in the control system design. The core tool inthis design environment is the model editor SystemBuild which is based on functionalflow block diagrams. The presented method is illustrated using the development of theGripen fighter aircraft flight control system as an example.

    Simulink as a Core Tool in Development of Next Generation Gripen2008In: Proceedings of Nordic Matlab User Conference 2008, Stockholm, Sweden, 2008Conference paper (Other academic)
    Abstract [en]

    In the planning and concept study phases of the next generation Gripen fighter aircraft, methods and tools studies have been performed. Capabilities and limitations of the Simulink toolset have been evaluated to explore how it can support model based systems/software engineering. In this paper, three different approaches of Simulink usage for functional development are presented:

    1. The functional oriented systems modeling and simulation approach where the function is in focus; complete enough to be simulatable, but abstract from an implementation point of view.
    2. An implementation oriented specification approach that is based on a modeling framework with predefined system architecture, scheduling, data types and rules for discretization. The resulting embedded software is hand coded using the model as specification.
    3. Similar to approach two but here the embedded software is automatically generated using a high quality code generator.

    The driver for choosing approach is threefold; high quality, short development time and low cost. Some experiences based on these prerequisites are presented, mainly concerning the aspects of scalability, such as; model architecture, license model and project ramp-up challenges. The results are also compared to the existing SystemBuild based development environment. When introducing high-end engineering practices and tools such as Simulink in an organization developing safety-critical products, it is important to make sure that also basic management practices (e.g. Requirements-, Configuration- and Change Management) are thoroughly handled.

    Abstract [en]

    Background: The board of directors is considered being an important part of corporate governance. One purpose of the board is to monitor the managers. When there is a separation between managing and ownership of a company, agency costs occure. This happens when companies are listed. The auditors purpose is to reduce the agency costs. Because of this, it is relevant to study how board characteristics affect audit quality.

    Purpose: This paper aims to explain how board characteristics affect audit quality.

    Method: This study is based on a deductive approach. Theories used in this study are agency theory, Corporate Governance Strategy and stewardship theory. A quantitative study of annual reports and databases have been done. The empirical datasets are collected from the years 2016 and 2017.

    Conclusion: The results from this study show that board characteristics affect audit quality at companies listed at Nasdaq Stockholm.

    A Co-Simulation Approach for Hydraulic Percussion Units2018Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This Licentiate of Engineering thesis concerns modelling and simulation of hydraulic percussion units. These units are often found in equipment for breaking or drilling in rock and concrete, and are also often driven by oil hydraulics, in which complex fluid-structure couplings are essential for their operation.

    Current methodologies used today when developing hydraulic percussion units are based on decoupled analyses, which are not correctly capturing the important coupled mechanisms. Hence, an efficient method for coupled simulations is of high importance, since these mechanisms are critical for the function of these units. Therefore, a co-simulation approach between a 1D system simulation model representing the fluid system and a structural 3D FE-model is proposed.

    This approach is presented in detail, implemented for two well-known simulation tools and evaluated for a simple but relevant model. The Hopsan simulation tool was used for the fluid system and the FE-simulation software LS-DYNA was used for the structural mechanics simulation. The co-simulation interface was implemented using the Functional Mock-up Interface-standard.

    The approach was further developed to also incorporate multiple components for coupled simulations. This was considered necessary when models for the real application are to be developed. The use of two components for co-simulation was successfully evaluated for two models, one using the simple rigid body representation, and a second where linear elastic representations of the structural material were implemented.

    An experimental validation of the co-simulation approach applied to an existing hydraulic hammer was performed. Experiments on the hydraulic hammer were performed using an in-house test rig, and responses were registered at four different running conditions. The co-simulation model was developed using the same approach as before. The corresponding running conditions were simulated and the responses were successfully validated against the experiments. A parameter study was also performed involving two design parameters with the objective to evaluate the effects of a parameter change.

    This thesis consists of two parts, where Part I gives an introduction to the application, the simulation method and the implementation, while Part II consists of three papers from this project.

    Abstract [en]

    This paper addresses a co-simulation method for fluid power driven machinery equipment, i.e. oil hydraulic machinery. In these types of machinery, the fluid-structure interaction affects the end-product performance to a large extent, hence an efficient co-simulation method is of high importance. The proposed method is based on a 1D system model representing the fluid components of the hydraulic machinery, within which structural 3D Finite Element (FE) models can be incorporated for detailed simulation of specific sub-models or complete structural assemblies. This means that the fluid system simulation will get a more accurate structural response, and that the structural simulation will get more correct fluid loads at every time step, compared to decoupled analysis. Global system parameters such as fluid flow, performance and efficiency can be evaluated from the 1D system model simulation results. From the 3D FE-models, it is possible to evaluate displacements, stresses and strains to be used in stress analysis, fatigue evaluation, acoustic analysis, etc. The method has been implemented using two well-known simulation tools for fluid power system simulations and FE-simulations, respectively, where the interface between the tools is realised by use of the Functional Mock-up Interface standard. A simple but relevant model is used to validate the method.

    Abstract [en]

    In this study a previously developed co-simulation method that is based on a 1D system model representing the fluid components of a hydraulic machinery, within which structural 3D Finite Element (FE) models can be incorporated for detailed simulation of specific sub-models or complete structural assemblies, is further developed. The fluid system model consists of ordinary differential equation sub-models that are computationally very inexpensive, but still represents the fluid dynamics very well. The co-simulation method has been shown to work very well for a simple model representing a hydraulic driven machinery. A more complex model was set up in this work, in which two cylinders in the hydraulic circuit were evaluated. Such type of models, including both the main piston and control valves, are necessary as they represent the real application to a further extent than the simple model, of only one cylinder. Two models have been developed and evaluated, from the simple rigid body representation of the structural mechanics model, to the more complex model using linear elastic representation. The 3D FE-model facilitates evaluation of displacements, stresses, and strains on a local level of the model. The results can be utilised for fatigue assessment, wear analysis and for predictions of noise radiation.

    Validation of a co-simulation approach for hydraulic percussion units applied to a hydraulic hammer2019In: Advances in Engineering Software, ISSN 0965-9978, E-ISSN 1873-5339, Vol. 131, p. 102-115Article in journal (Refereed)
    Abstract [en]

    In this study, a previously developed co-simulation approach has been adopted to simulate the responses of an existing hydraulic hammer product. This approach is based on a 1D system model representing the fluid components and a 3D finite element model representing the structural parts of the hydraulic hammer. The simulation model was validated against four experiments with different running conditions. The corresponding set-ups were analysed using the co-simulation method in order to evaluate the overall responses. A parameter study was also performed involving the working pressure and the restrictor diameter, with the objective to validate that a parameter change in the simulation model will affect the input and output power in the same direction as in the experiments. The experimental responses used in the validation were time history data of fluid pressure, component position and acceleration, and structural stresses. The experiments result in high frequency and high amplitude excitations of the hydraulic hammer and thus require a model with a high resolution of the model dynamics. The conclusion of the validation is that the simulation model is able to replicate the experimental responses with high accuracy including the high frequency dynamics. The favourable outcome of the validation makes the described co-simulation approach promising as an efficient tool for a wide range of other applications where short time duration mechanisms need to be studied.

    Contrasting as a research strategy for highlighting polyphonic sensemaking in stories of organizational life2011Conference paper (Refereed)
    Abstract [en]

    Field work is a phenomenal but unpredictable source of material for those of us interested in stories of organizing and sensemaking about organizational life. When entering the field we meet people engaged in work and in organizations, who are often keen to tell us what’s going on. These meetings can be both stunning and overwhelming. Where do I start to listen, and where should I stop? The stories of the organization never stop, as new and reoccurring activities needs to be made sense of in the discussions with other organizational actors (Boje, 1991). By relating ongoing events to stories, life in the organization is made meaningful (Czarniawska, 1999). Not all stories of day-to-day life are told with a clear beginning, plot and end, though. The fieldworker interested in narrating the organization becomes a collector of fragmented story parts, and needs to reassemble these parts into a comprehensive whole that can make sense to a reader. The stories possible to tell often become numerous, especially with a longitudinal field study approach. Then how do we choose which stories to tell and how to tell them? One approach is to reassemble several stories told by different actors but relating to the same issue and contrast them against each other. In this paper, experiences of using contrasting as a research strategy for story construction and analysis within one single case study are highlighted and discussed from a sensemaking approach to organizing. The paper illustrates how contrasting can be a used both as a means of embracing polyphony and for avoiding the pitfall of drawing too much attention to consensus building and shedding too little light on conflict, a critique voiced against sensemaking research (Skålén, 2002). Up until now, only a modest amount of empirical research has been done on sensemaking and this is an important research agenda (Weick et al., 2005). This paper contributes to problematizing how empirical research can contribute to the understanding of sensemaking in organizations.

    Deconstructing the Motives of Constructing an Intermediary between Public Services and Private Entrepreneurs2011Conference paper (Refereed)
    Abstract [en]

    Intermediary organisations constructed as a link between public service providers and business entrepreneurs is a phenomena which we know very little of. Given the difficulty of relating concrete effects to investments made in business support ventures, we need to know more about the specific arguments behind this organisational construction. When deconstructing the arguments behind one particular venture, several lines of reasoning unfold, revealing motives founded on miscellaneous legitimating elements. The analysis reveals a situation where striving for legitimacy is sometimes more important than actual results and where the private entrepreneur is both the target and the role model.

    Hybrid aspects in a public collaboration project - A sensemaking approach to understanding hybridization2008In: Latin American European Meeting on Organization Studies Colloquium,2008, 2008Conference paper (Other academic)
    Abstract [en]

    Hybrids are often thought of as mixtures of organizational models. This paper explores a case that shows how hybridization can occur along several dimensions and discusses how people handle and make sense of hybridity in several aspects. The case of -C to C- is interpreted in terms of an organizational process embedded in a hybrid setting characterized by hybridity in terms of strategic alliances, project organizing in a bureaucratic organizations, and company ideals in public settings. All these characteristics have in common that they imply hybridization between supposed opposites (c.f. Courpasson & Clegg, 2006). The paper displays how a sensemaking approach can be used to further the understanding of hybridization, through directing attention to how people handle uncertainty and ambiguousness in hybrid situations. The paper also point to aspects of hybridity not often discussed in the literature on hybrids; such as hierarchical power relations.

    Interprenörskap - Ett FöretagsNära entreprenörskap i det offentligas regi2008In: Perspektiv på förnyelse och entreprenörskap i offentlig verksamhet, Örebro: Forum för Småföretagsforskning , 2008, 1, p. 107-121Chapter in book (Other academic)
    Abstract [sv]

    I det här kapitlet diskuteras samverkanssatsningen FöretagsNära som ett exempel på förnyelse av verksamhet i offentlig sektor på tre olika sätt. Frågan jag ställer är om dessa tre aspekter går att förstå med hjälp av entreprenörskapsteori. Det finner jag att de gör. För det första är satsningen förnyande genom sättet att organisera verksamheten på. Detta kan förstås som en form av organisatoriskt entreprenörskap. För det andra innebär satsningen också förnyelse i och med att det handlar om en satsning på en tidigare förbisedd målgrupp för kommunens verksamhet. Detta kan förstås som en form av samhällsentreprenörskap. För det tredje är verksamheten nydanande genom att dess huvudsakliga syfte är att koppla ihop företag med andra företag och även med samhällsorganisationer som kan stötta dem i utveckling och tillväxt. Fokus på den här aspekten av entreprenörskap har inte en framskjuten position inom entreprenörskapslitteraturen. Jag föreslår därför begreppet interprenörskap för att förtydliga och förstå de här aspekterna.

    När strävan efter samsyn blir en kamp: Meningsskapande och meningsgivande i mångtydiga sammanhang2010Doctoral thesis, monograph (Other academic)
    Abstract [en]

    When people and groups with different backgrounds and experience are brought together to cooperate, a prerequisite for coordinated action is often a shared per-spective, i.e. that they have a mutual understanding with regard to the aims of their work. However, previous research has not been able to conclude empirically whether a shared perspective is essential for bringing about joint action or not. This dissertation is the result of a study inquiring into the connection between co-incident meaning and coordinated action in situations characterised by heteroge-neity and equivocality. How does coordinated action originate in such circum-stances? The empirical case of the study is “FöretagsNära” (“Close to Companies” in English), a collaboration project between the municipality of Norrköping and the local branch of the state employment agency. The purpose of the venture is to coordinate the efforts of measures aimed at trade and industry development with labour market measures, in order to contribute to a decrease of the unemployment rate in the city of Norrköping. Based on a longitudinal field study, a narrative of clashing meanings, and a striving for mutual perspectives unfolds. The longitudi-nal approach supports an understanding of how joint action unfolds and the com-plexity involved in developing a shared perspective. The description of Företags-Nära shows that the creation of meaning in the process takes on different expressions, and a battle of meaning arises about the matter of the purpose of FöretagsNära. The connection between a shared perspective and joint action is more complex than previous research has suggested. There is no unequivocal connection between coincident meaning and coordinated action. The results of the thesis are of both theoretical relevance and practical importance.

    Organisering för samordning och samsyn: En studie av Kindas kärntrupp för rehabiliteringssamverkan kring äldre2012Report (Other academic)
    Abstract [sv]

    Samverkan blir allt vanligare som organisatorisk lösning på situationer där ansvarsområden är vaga eller skär över organisationsgränser. Inom området vård och omsorg om äldre korsar ansvaret gränser både avseende huvudmän och yrkesgrupper och satsningar på samverkan är därför frekvent förekommande. Särskilda satsningar på samverkan inom just rehabiliteringsområdet har också främjats av statliga stimulansmedel riktade mot vården och omsorgen om äldre.

    Föreliggande studie belyser hur kärntruppen, en grupp bestående av representanter för olika yrkesgrupper och huvudmän med ansvar för olika uppdrag i rehabiliteringen av äldre i Kinda kommit att samverka i syfte att skapa bättre samordning och samsyn kring brukaren.

    Materialet som studien bygger på består av fem års kontinuerliga mötesanteckningar, personliga intervjuer, en fokusgruppsintervju, ett års kontinuerligt nedskrivna mötesdagböcker samt övrig dokumentation om verksamheten.

    Studien visar hur samverkan kan utvecklas och samsyn frammanas i viktiga frågor genom att rätt personer involveras, personligt engagemang skapas och tid ges till diskussion om frågor som lyfts upp och bearbetas efter hand. Sett ur ett meningsskapandeperspektiv framträder betydelsen av gemensamma aktiviteter vid olika mötesarenor för den samsyn som åstadkoms. Brukaren, eller ”Kalle”, blir det objekt som företrädare för samtliga inblandade organisationer och yrkesgrupper kan samlas kring. Genom mötet dem emellan framträder kärntruppen som en organisation som fungerar som en länk mellan olika världar likväl som en brobyggare för att inkludera även andra i ett alternativt synsätt på brukaren.

    Private sector norms in a public sector project: Picturing diverging images of project organising2007In: European Academy of Management,2007, 2007Conference paper (Refereed)
    Abstract [en]

    Earlier research suggests that public and private organisations have different reasons for organising in projects, and taking contextual factors into consideration is important in understanding project organising and management. This paper concerns how people involved in organising a project experience divergences in project organising norms and how those differences affects the organising process. The paper is based on a case study of a public sector project where four persons from the private sector have been recruited to a municipal project. From their perspective, I tell a story of how private sector project norms clash with public sector ways of organising.

    Small business promotion and intermediating as societal entrepreneurship2012In: Societal Entrepreneurship: Positioning, Penetrating, Promoting / [ed] Karin Berglund, Bengt Johannisson, Birgitta Schwartz, Cheltenham: Edward Elgar Publishing, 2012, 1, p. 117-138Chapter in book (Other academic)
    Abstract [en]

    Most social ventures cross the boundaries between the private, the public and the non-profit/voluntary sectors, and this broad involvement of actors and intertwining of sectors makes the label 'societal' entrepreneurship more appropriate. Stating the importance of both the local and the broader societal context, the book reports close-up studies from a variety of social ventures. Generic themes include positioning societal entrepreneurship against other images of collective entrepreneurship, critically penetrating its assumptions and practices and proposing ways of promoting societal entrepreneurship more widely.

    Onormalt låga anbud i offentliga upphandlingar: Begreppets innebörd, bevisbördans placering och effekter av det nya upphandlingsdirektivet2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Inom offentlig upphandling strävar myndigheter efter att anskaffa varor, byggentreprenader eller tjänster till ett så lågt pris som möjligt utan att kvaliteten eftersätts. Antagande av anbud som är så låga att inte anbudsgivaren klarar av att leverera till det offererade priset eller till den utlovade kvaliteten riskerar dock att i förlängningen medföra ökade kostnader för den upphandlande myndigheten, vilket inte innebär en effektiv användning av offentliga medel.

    Huvudregeln är att samtliga anbud som lämnas i en offentlig upphandling ska utvärderas av den upphandlande myndigheten. I 12 kap. 3 § Lagen (2007:1091) om offentlig upphandling finns dock ett undantag från huvudregeln, vilket ger upphandlande myndigheter en möjlighet att förkasta onormalt låga anbud. Det saknas emellertid en definition av vad som utgör ett onormalt lågt anbud. Det råder även viss tveksamhet vad gäller placeringen av bevisbördan för att ett onormalt lågt anbud som kan förkastas föreligger. Osäkerheten avseende innebörden av begreppet onormalt lågt anbud samt bevisbördans placering kan medföra att upphandlande myndigheter sällan utnyttjar möjligheten att förkasta onormalt låga anbud.

    Den slutsats som kan dras vad gäller vad som ska förstås med begreppet onormalt lågt anbud är att det inte är lämpligt att ta fram en generell definition av begreppet. Istället bör en sammantagen bedömning göras för att fastställa huruvida ett onormalt lågt anbud föreligger, eftersom det torde underlätta för upphandlande myndigheter dels att identifiera misstänkt låga anbud, dels att bedöma huruvida de också är onormalt låga. I bedömningen bör hänsyn tas till anbudsgivarens leveransförmåga, marknadspris, nivån på övriga anbud i upphandlingen och anbudets seriositet.

    Vad gäller bevisbördans placering tyder praxis på att EU-domstolen har ansett att bevisbördan bör vara delad mellan parterna medan svenska domstolar har placerat hela bevisbördan hos den upphandlande myndigheten. På grund härav har kan det hävdas att svenska domstolar beslutat i strid med vad EU-domstolen har uttalat, vilket strider mot såväl principen om EU-rättens företräde som lojalitetsplikten. Svenska domstolar har således förbisett både sekundär- och primärrätten. Det är dock sannolikt att placeringen av bevisbördan kommer att justeras av svenska domstolar i och med ett nyligen avgjort mål, där Kammarrätten i Göteborg ålade anbudsgivaren bevisbördan för anbudets seriositet.

    Vidare har ett nytt upphandlingsdirektiv nyligen antagits, i vilket strängare regler om onormalt låga anbud har införts. Genom de strängare reglerna säkerställs bland annat att det råder lika villkor mellan anbudsgivarna, vad gäller efterlevnad av miljö-, social- och arbetsrättslig reglering, vilket torde bidra till främjandet av effektiv konkurrens. Det kan däremot ifrågasättas huruvida artikel 69 om onormalt låga anbud i det nya upphandlingsdirektivet kommer att leda till ökad förutsebarhet, då det inte framgår vad som ska förstås med begreppet onormalt lågt anbud. Utformningen av artikeln i kommissionens ursprungliga förslag gav däremot ledning angående vilka faktorer som kan indikera att ett onormalt lågt anbud föreligger. Det kan därför antas att förslaget skulle ha lett till ökad förutsebarhet avseende vilka faktorer som bör tillmätas betydelse i bedömningen.

    Avslutningsvis, vad gäller frågan om varför det i det nya upphandlingsdirektivet inte föreskrivs ännu strängare regler angående onormalt låga anbud, kan slutsatsen dras att det inte torde vara lämpligt att föreskriva en regel som automatiskt förkastar sådana anbud. En sådan regel riskerar att strida mot likabehandlingsprincipen eftersom den skulle innebära att det kontradiktoriska förfarandet inte skulle tillämpas.

    Att godtrosförvärva lösöre: En analys av förvärvarens undersökningsplikt2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I situationer när egendom har överlåtits utan den ursprunglige ägarens tillåtelse eller vetskap kan lag (1986:796) om godtrosförvärv av lösöre bli tillämplig. Lagen reglerar vem, av den ursprunglige ägaren och förvärvaren, som ska tillmätas äganderätten till egendom som har överlåtits av någon som inte hade rätt att överlåta egendomen. Exempel på situationer då lagen kan tillämpas är att en person som har lånat egendom överlåter denna till tredje man eller att någon överlåter egendom som är belagd med äganderätts- eller återtagandeförbehåll. I lagen uppställs krav på förvärvarens aktsamhet och undersökning för att denne ska anses ha gjort ett godtrosförvärv och därmed tillmätas äganderätten till egendomen. Anses förvärvaren ha varit i ond tro vid förvärvet ska egendomen återföras till den ursprunglige ägaren.

    Godtrosförvärvslagen började gälla år 1987 och det har därefter gjorts ändringar vid två tillfällen. Den första ändringen var tänkt att försvåra möjligheten att godtrosförvärva egendom och gäller sedan år 1999. Efter den andra ändringen, år 2003, är det omöjligt att godtrosförvärva stulen egendom. Däremot finns fortfarande möjligheten att godtrosförvärva egendom i de fall överlåtaren lovligen har egendomen i sin besittning, men inte ägde rätt att överlåta den. I dessa fall är dock frågan hur omfattande förvärvarens undersökningsplikt är i praktiken, för att denne ska anses ha varit i god tro vid förvärvet, och om ändringen år 1999 har gjort det svårare att förvärva egendom i god tro.

    Genom vår analys, av främst praxis från både före och efter 1999 års lagändring, visar det sig att det har blivit svårare för privatpersoner att göra godtrosförvärv. På näringsidkare ställs dock samma höga krav som före ändringen, vilka alltid har varit högre än på privatpersoner. Viss typ av egendom anses vara känslig, på grund av dess värde och det faktum att den vanligen är behäftad med äganderätts- eller återtagandeförbehåll. Det krävs därför att förvärvare av sådan egendom vidtar långtgående undersökningar.

    Förvärvaren ska före förvärvet, oavsett vilken typ av egendom det är, kontrollera överlåtarens identitet, fråga överlåtaren om tidigare ägare samt begära att få se kvitto och köpekontrakt från egendomens senaste överlåtelse. I de fall egendomen finns registrerad ska förvärvaren inhämta information från det aktuella registret. Om förvärvaren erhåller kontaktuppgifter till tidigare ägare ska dessa kontaktas. Påstår sig överlåtaren handla för annans räkning måste förvärvaren kontrollera detta med den eventuelle fullmaktsgivaren.
