    Engaged Scholar(ship) in purchasing and supply management (PSM): Creative tension or squeezed in the middle?2019In: Journal of Purchasing and Supply Management, ISSN 1478-4092, E-ISSN 1873-6505, Vol. 25, no 4, article id 100557Article in journal (Refereed)
    Abstract [en]

    Purchasing and supply management research influences practice through the advancement of knowledge and theoretical principles and is positioned as an academic discipline. For the individual researcher, it calls for skills and experience that can be associated with engaged scholarship. This paper explores tensions inherent in engaged scholarship, that arise during the quest to interact closely with professionals to ensure relevance and impact while living up to research quality criteria. The paper concludes that the individual researcher in a field such as PSM is easily left with guidelines that point in multiple directions regarding personal achievement and institutional merits.

    Customizations vs. Platforms: A Conceptual Approach to COSI2018In: Advances in Production Management Systems. Production Management for Data-Driven, Intelligent, Collaborative, and Sustainable Manufacturing. APMS 2018. / [ed] I. Moon, G. Lee, J. Park, D.

    Abstract [en]

    In recent years, many manufacturers have experienced an increased demand for customized products and services, which requires the manufacturer to simultaneously offer both standardized and customized products. Consequently, several manufacturing strategies must be efficiently employed. These companies do not express the same prerequisites as ‘pure’ ETO companies since they need to be able to differentiate customized orders from standard orders, but also be able to differentiate between the manufacturing dimension and the engineering dimension of customization. Whereas standard orders can be processed with a platform approach, the customized orders contain specific requirements and information represented by ‘customer-order specific information’ (COSI). This paper defines and presents competitive scenarios where platform constraints are combined with COSI for efficient customizations. Implications for the approach and a path forward is discussed.

    Investigating the Aspect of Interaction in the Mobile Manufacturing Concept2007In: NOFOMA 2007, 2007Conference paper (Refereed)
    Abstract [en]

    The aim of the mobile manufacturing concept is to provide solutions for mobile and flexible manufacturing capacity on demand. The idea with the concept is that a mobile manufacturing unit (MMU) could sent to the place where it is needed, either within the company, to a local supplier, to a customer, or to a partner, in order to, for example, cover a temporary volume peak.

    Within the research project Factory-in-a-Box, five fully operative MMUs have been designed and realized in close contact with Swedish manufacturing industries. The main logistic focus within the research project has been put on optimizing the transport solutions, while the implications on the relations in the supply chain have still not been analyzed. It is however, important to clarify that the geographical and organizational distance between the stationary site and the site where the MMU temporarily is located, affects the complexity of the information and material flow. In order to secure MMU productivity, both information and material flow to and from the stationary factory, the stationary factory’s sub-suppliers, the local suppliers, and the customer, must be handled.

    In order to use the MMU’s resources efficiently, the level of interaction with all these actors has to be selected wisely. Therefore, the aim of this paper is to investigate the information flow and material flow in one of the demonstrators within the Factory-in-a-Box project, in order to highlight the importance of selecting appropriate level of interaction and how mobility affects the supply chain relations.

    Abstract [sv]

    Syftet med detta papper är att undersöka hur graden av kundanpassning av ingående komponenter påverkar kostnad och ledtid. För att illustrera denna situation används ett exempel från hydraul pumptillverkaren Parker från när en ingående komponent ändrades från standard till kundunik utan att analysera hur detta påverkade ledtider och leveransförmåga. I pappret visar vi att KDI-metoden som simultant tar hänsyn till strategiska ledtider, grad av kundanpassning och kundorderns position ökar möjligheterna att ta väl underbyggda beslut, att undvika suboptimering och där igenom minska totalkostnaden.

    Samordning av grad av samverkan och grad av kundorderstyrning2008In: PLANs Forsknings- och tillämpningskonferens: logistikutveckling - teori möter praktik : artiklar från konferensen på Chalmers tekniska högskola 27-28 augusti 2008, Stockholm: PLAN - Logistikföreningen , 2008Conference paper (Other academic)
    Abstract [en]

    Olika aspekter på samverkan har rönt stor uppmärksamhet under de senaste årtiondena men har endast i begränsad omfattning integrerats med centrala produktions- och logistikstrategiska beslutskategorier. Ett område som till stor del varit frånvarande i forskningen om kund/leverantörssamverkan är kopplingen till olika grader av kundorderstyrning. Sedan länge har graden av kundorderstyrning ansetts som ytterst central i utformningen av strategier för produktions- och logistiksystem men har trots detta sällan inkluderats i olika modeller för val av grad av samverkan mellan företag. Denna brist på samordning av två så viktiga kunskapsdomäner innebär att avgörande pusselbitar troligen saknas i kunskapen om hur konkurrenskraftig industriell verksamhet bedrivs i samverkan. Dessa två perspektiv har stor påverkan på utformning av både produkter och logistiksystem. Om man dessutom beaktar den snabba förändringstakten på dagens marknader och den dynamik som då skapas så finns det mycket starka motiv för att säkerställa att rätt grad av samverkan med andra parter i försörjningsnätverket etableras för att kunna hantera de osäkerheter som finns om marknadens behov.

    Förbättringsarbete inom materialhantering: På företaget ORWAK AB2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    ORWAK AB is a market leading manufacturer of compaction and baling solutions for solid waste materials like corrugated cardboard, plastics and paper. The company strives for continuous development of their processes and operations with the goal to achieve better efficiency to be able to supply their customers with new innovations and high-quality products. Their vision is “Turning Waste Into Value”

    The purpose of this study has been to identify losses related to the company’s internal supply and management of materials. The study has been limited to a single production line which was chosen together with the company because of its good attributes for generalization. It was also necessary as the consequence of the limited time span. In addition, the purpose of the study has been to develop an action proposal on how to solve the identified losses. To be able to identify the losses the study has processed a numerous of logistics and production theories to constitute an understanding of how an efficient supply of materials can be achieved.

    The empirical research was constructed by the help of observations, interviews, conversations and different time studies. The time studies that was conducted yielded data about how different activities related to each other in frequency and time. The activities were classified into different categories to determine which activities that was adding value, and which were not. This made it possible to determine the total loss of the studied production line. As a total, 17% of the documented activates was categorized as losses.  

    The analysis connects the identified losses with different aspects of applicable theory to identify and solve them. These connections then create the foundation for the action proposal that has been presented. The result of the action proposal was to implement a more specific standard about how production and warehouse related activities should function, reform the current tool and material racks in production and remove unnecessary pallets, equipment and tools which is not of use. A new production line layout which improves the flow and handling of material for the operators as well as reduces the losses identified to supply of material. The action proposal also presents a suggestion to implement a new module to the company’s current ERP-system to solve the lack of information flow between the warehouse and production regarding material levels, locations and material call offs.

    An interface model based on damage coupled to slip and dilatation1998In: Fracture from defects: Proceedings of the 12th Bienniel Conference on Fracture - ECF, held in Sheffield, U.K., 14-18 September 1998, West Midlands, U.K.: Engineering Materials Advisory Services , 1998, p. 957-962Conference paper (Refereed)
    Abstract [en]

    The mesomechanics behavior of a polycrystalline microstructure subjected to creep and constant strain rate loadings is investigated. The analysis is based on a Voronoi polygonization strategy for the generation of grains, that are bonded to each other via interfaces along the grain boundaries. A new constitutive model is proposed for the rate-dependent debonding along these interfaces, whereby damage is kinetically coupled to viscoplastic slip and dilatation. The paper may be viewed as generalizing the rate-independent model used in Cannmo et al. (1995).

    Characteristics of microstructure and banded defects in die-cast AM50 magnesium components2005In: International Journal of Cast Metals Research, ISSN 1364-0461, E-ISSN 1743-1336, Vol. 18, no 6, p. 377-384Article in journal (Refereed)
    Abstract [en]

    It has become more and more common for companies to move part of their production to low cost countries and/or closer to important markets. However, quite often the product development is not moved. The result is an increased distance between product development and production. The interface between the two departments is important to lead time, cost and quality and therefore the cooperation must work smoothly. To achieve this, most literature recommends early and tight cooperation. However this can be complicated by expensive and time consuming travels and/or usage of less rich communication such as emails and phone calls.

    It is difficult to make the transition in general from product development to production and the possible problems increase with the distance. The PD-P interface consists of several components and how a problem in one component is affected by problems in other components is not explicitly discussed in literature. The purpose in this paper is to explore if there are such connections i.e. connections between an observable problem and other components in the PD-P interface in a geographically dispersed setting. The paper does so by merging the distributed work literature and the PD-P interface literature.

    The analysis is based on four PD-P interface components; technological, organizational, scope and task. The analysis indicates that observable problems as e.g. low frequency of communication can be the symptom of one or a combination of problems. Connections between the components in the PD-P interface are exemplified in a geographically dispersed setting. Furthermore the underlying causes to the problems connected to the geographically dispersed setting in the PD-P interface are elucidated. In the case of low frequency of communication, it could be the technical system hindering communication and the different time zones disrupt it even more. Hence one symptom could be caused by different underlying problems. Each problem needs to be broken down to find the cause and the solution could be found in any of the four interface components.

    The results indicate that the actual distance is not the biggest problem but uncertainties (e.g. new collaborations) and differences (culture and work methods) which increase lead time. We have also seen that single underling problems can cause problem in several of the PD-P interface components. This indicates that if these underlying problems can be solved the project results can be vastly improved. For example, trust issues occur in the scope component (affects the willingness to share information) and in the organizational interface component (both competence trust and goodwill trust affects involvement and commitment to the project). Consequently, if problems like this can be solved many other problems will become minor problems and project objectives will be more likely to be obtained. However trust is difficult to achieve with a geographical distance between product development and production. The analysis also indicates that due to the distance more attention is paid to the PD-P interface, e.g. more experienced team members are appointed. This can be contributing to a smoother PD-P interface than expected.

    Beläggning - Ett planeringssystem2009Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis has been carried out in cooperation with System Andersson that develops, manufactures and installs engineering system. This is a proposal on how a system can be designed because the market has become more demanding.

    This thesis subject is to come with ideas on how a system might look like. As a starting point, a number of questions were made. For example, what happens if the capacity or planning does not agree with the plane, and how does a planner’s normal day look like.

    To carry out the work the authors have used the literature review based on previous literature in their program, interviews of personnel at System Andersson and own ideas.

    System Anderssons customers are mainly small and medium-sized, Swedish manufacturing companies. The most common is that the customers work in a job shop and manufacturing that order. In this segment, that System Andersson will continue to work in, it is important to the engineering system can change the operation sequence and optimize the capacity utilization of machinery and personnel. For the product to be competitive, it must also be designed for the people who use the program.

    Some of the results consist of two versions of the coating module,

    What is new in this proposal to the version they are selling today are: more features, daily planning, capacity planning and graphic. The authors have come up with ideas in the program on how this should be soluble.

    The program is from the scheduler point of view to help with the daily work and solve the problems before they arise or be more flexible to manage. From System Anderssons point of view, this could be used in marketing and promoting their programming when they talk with customers.

    Light, and Advanced. The first is targeted to small businesses and therefore contains only the most important functions for the coating design; the remainder is as scaled as possible. The latter version, Advanced, is adapted to the somewhat larger firms and can therefore perform a wider range of tasks. It should be suitable for a full-time planner with all that that implies. In addition to these two versions the authors have designed a time clock and a dispatch list to create a better overall picture of occupancy planning. The time clock is used to collect information on available staff capacity and dispatch list to communicate to the manufacturing and update the available machine capacity. The authors' focus has been to draw up the overall sketches and not the program behind.

    Phases of Co-Production: Follow-up Research on the Industrial Research School INNOFACTURE2015Conference paper (Refereed)
    Abstract [en]

    Mälardalen Univerity is characterised by its close collaboration with companies and with the public sector in the region. A main strategic directions of the university is to develop co-production with partner companies, expressed in the university vision “A Strong MDH – the Coproducing University”. The concept ’co-production’ is in this paper used interchangeably with concept ’co-creation’, emphasising our view of equal participation and interaction with the goal of knowledge, that by the company can be made useful outside the university (see Terblanche, 2014). Based on Mälardalen University’s vision, co-production is a main goal for the Innovation and Product Realization (IPR) environment. IPR is located at the School of Innovation, Design and Engineering and has a common graduate education with three mutually supportive cooperating research groups: Product realization, Innovation management, and Information design. Here ideas from different fields and cultures meet, creating new ideas, possibilities, and knowledge as a result. The approach to develop new insights and knowledge in order to address societal challenges, through working closer between academics and research users, has a potential to improve how research is conducted. Still, there are many questions and challenges in this approach, with need of development: How is research and research education framed and undertaken? What constitutes co-production? What distinguishes reseach in co-production from other forms of research? What are the benefits and barriers of co-production? As we shall see, the follow-up research aim to contribute to how our third level education in a co-production environment can be undertaken.

    Sammanställning av riktlinjer för logistiken på Isaberg Rapid AB2009Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Isaberg Rapid AB is a company that manufactures for instance staplers and glue guns. Headquarters and main factory is located in Hestra but there are also subsidiary companies in Denmark, Netherlands, France, Spain, China and England. There are also two filial factories in France and China.

    Today has the company no logistic guidelines committed and that leads to problems since the salesmen promise different things to the customers. This contributes too many different logistic solutions for Isaberg Rapid AB. The company has also noted problems with returns of goods.

    The purpose with this task is to standardize and compile logistic guidelines, usable to all Isaberg Rapid AB's small to midsize customers. The aim is to increase the flow of information and reach a more standardized way to work than previously within the company and between the company and their customers. The task also includes development of a functioning system of returns usable to all customers.

    Choice of methods has changed from literature studies to focus on interviews and document collections at the company. A large part of the implementation is comprised of interviews. This because the task were directed to Isaberg Rapid AB and it were therefore difficult to find any appropriate theory. Some visits, both in Hestra and Saint Amé, have been made. In development of the logistic guidelines have two other logistic guidelines from the company's customers been studied.

    In the result part is the compiling of the logistic guidelines presented. The logistic guidelines are based on the collected documents from the company but also include parts from interviews and the studied logistic guidelines. This document should work as a tool for customers and concerned people at Isaberg Rapid AB. It contains important information before, during and after ordering. There are two versions of this document, one for the customer and one to use internally with extra comments.

    In the end of the report there are some discussions about the difficulties that have been discovered. Finally, the questions given in the problem description will be answered in the conclusions.

    Design of a full-sized NFC Desktop Keyboard for Smart Devices2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The master´s thesis project was performed in collaboration with the design and engineering company Eker Design from Fredrikstad in Norway, who is designing and developing flip cover NFC keyboards for smartphones.

    The new product idea is the full-sized NFC desktop keyboard for public institutions to offer to pupils, students or business people for instance.

    The thesis project is examining how such a product can be designed and should be designed in order to fit into its market and environment to meet the target group´s interest in order to be successful.

    With a human-centered design approach the project work was starting by the user and the market. The work consisted of analyzing and emphasizing with the market which mainly included the users, the competitors and the trends within a market analysis and a survey research.

    From the findings and insights of the research phase a design strategy and a business model for the new keyboard was created and communicated via a design brief.

    Different ideas and concepts were created, tested and presented via concept sketches along with mock-ups. The final concepts were evaluated via a concept evaluation in relation to the requirements of the business and user value.

    The final concept was developed and designed via the CAD software SolidWorks and the rendering software Keyshot. The design and development phase was focusing on functionality, usability, materials, surfaces, textures and the mechanical and technical solutions for the design.

    The result of this thesis project is named TRANSIT and is presenting how a collapsible desktop keyboard which is offering a NFC connection could look like and work to offer to people in public places such as libraries or universities and be as well be suitable for people to use at home.

    The TRANSIT keyboard is a simple and robust concept of a full-sized tactile keyboard which is offering a NFC connection as well as a Bluetooth connection for devices which do not support NFC yet. The design is aimed for smartphones and tablets and is offering a support which consists of an automated stand and a back plate which angle is adjustable step-less. The design allows to collapse stand, keyboard and back plate into a compact package which makes it easy to store and transport. Furthermore the design is providing a charging option for the smart device via energy harvesting or cable and has therefore internal batteries.  

    The project is ending with the final presentation of the physical model in scale 1:1.

    Towards a Strategy for Mapping of Design Problems to Suitable Solutions: A Case of Design Automation using CBR2007In: Strojarstvo, ISSN 0562-1887, Vol. 49, no 1, p. 17-24Article in journal (Refereed)
    Abstract [en]

    In order to make the designing of product variants more efficient and effective there often exists the possibility of automating the process, or at least implementing some form of computer support to aid the designers. Designing though, is often not a simple and single task. Instead, it often consists of several interlinked sub-tasks that have to be performed either in some previously known order, iteratively, or perhaps even by inference. Furthermore, the levels of knowledge and task formalisation and process maturity may vary from known and clearly documented tasks (explicit), to known but undocumented tasks (implicit), or even unclear and unstructured tasks (ad-hoc).

    In doing so a clearer picture of the actual design process will emerge and a problem definition and/or system specification can be outlined [Cederfeldt 2005]. This will in turn give rise to new questions that needs to be answered in parallel with setting up of a final system specification. Some of these questions address the choice of solution approach related to the design process and its inherent knowledge. This paper presents one such attempt at breaking down a design problem, defining its process character and capturing its inherent domain knowledge. This is then mapped to suitable tools, and computer implementations. One of the tools chosen in this work, Cased Based Reasoning (CBR), will be addressed further and some implementation issues of CBR as well as the advantages of a variant design approach to setting up of CBR indexing templates are discussed in more detail.

    Multi Criteria Classification for Spare Parts Inventory2008Conference paper (Refereed)
    Abstract [en]

    Maintenance operations directly influence the performances of railway vehicles and play a crucial role in railway services to provide uninterrupted and high quality service to passengers. With the exception of preventive activities, the demand of spare parts for maintenance tasks is usually random; hence, the fast and secure management of the spare parts inventory is an important factor for the successful execution of the maintenance process. The purpose of this research is to extend the classical ABC analysis by developing a multi-criteria inventory classifi- cation approach for supporting the planning and designing of a maintenance system. Relevant classifi- cation criteria and control characteristics of maintenance spare parts are identified and selected and discussed in terms of their effects on maintenance operations, purchasing characteristics, positioning of materials, responsibility of control, and control principles.

    Finite element methods for surface problems2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The purpose of this thesis is to further develop numerical methods for solving surface problems by utilizing tangential calculus and the trace finite element method. Direct computation on the surface is possible by the use of tangential calculus, in contrast to the classical approach of mapping 2D parametric surfaces to 3D surfaces by means of differential geometry operators. Using tangential calculus, the problem formulation is only dependent on the position and normal vectors of the 3D surface. Tangential calculus thus enables a clean, simple and inexpensive formulation and implementation of finite element methods for surface problems. Meshing techniques are greatly simplified from the end-user perspective by utilizing an unfitted finite element method called the Trace Finite Element Method, in which the basic idea is to embed the surface in a higher dimensional mesh and use the shape functions of this background mesh for the discretization of the partial differential equation. This method makes it possible to model surfaces implicitly and solve surface problems without the need for expensive meshing/re-meshing techniques especially for moving surfaces or surfaces embedded in 3D solids, so called embedded interface problems. Using these two approaches, numerical methods for solving three surface problems are proposed: 1) minimal surface problems, in which the form that minimizes the mean curvature was computed by iterative update of a level-set function discretized using TraceFEM and driven by advection, for which the velocity field was given by the mean curvature flow, 2) elastic membrane problems discretized using linear and higher order TraceFEM, which makes it straightforward to embed complex geometries of membrane models into an elastic bulk for reinforcement and 3) stabilized, accurate vertex normal and mean curvature estimation with local refinement on triangulated surfaces. In this thesis the basics of the two main approaches are presented, some aspects such as stabilization and surface reconstruction are further developed, evaluated and numerically analyzed, details on implementations are provided and the current state of work is presented.

    Finite element methods on surfaces2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The purpose of this thesis is to improve numerical simulations of surface problems. Two novel computational concepts are analyzed and applied on two surface problems; minimal surface problems and elastic membrane problems. The concept of tangential projection implies that direct computation on the surface is made possible compared to the classical approach of mapping 2D parametric surfaces to 3D surfaces by means of differential geometry operators. The second concept presented is the cut finite element method, in which the basic idea of discretization is to embed the d- 1-dimensional surface in a d-dimensional mesh and use the basis functions of a higher dimensional mesh but integrate over the surface. The aim of this thesis is to present the basics of the two main approaches and to provide details on the implementation.

    Minimal surface computation using a finite element method on an embedded surface2015In: International Journal for Numerical Methods in Engineering, ISSN 0029-5981, E-ISSN 1097-0207, Vol. 104, no 7, p. 502-512Article in journal (Refereed)
    Abstract [en]

    We suggest a finite element method for finding minimal surfaces based on computing a discrete Laplace–Beltrami operator operating on the coordinates of the surface. The surface is a discrete representation of the zero level set of a distance function using linear tetrahedral finite elements, and the finite element discretization is carried out on the piecewise planar isosurface using the shape functions from the background three-dimensional mesh used to represent the distance function. A recently suggested stabilized scheme for finite element approximation of the mean curvature vector is a crucial component of the method.

    Cut finite element modeling of linear membranes2016In: Computer Methods in Applied Mechanics and Engineering, ISSN 0045-7825, E-ISSN 1879-2138, Vol. 310, p. 98-111Article in journal (Refereed)
    Abstract [en]

    We construct a cut finite element method for the membrane elasticity problem on an embedded mesh using tangential differential calculus, i.e., with the equilibrium equations pointwise projected onto the tangent plane of the surface to create a pointwise planar problem in the tangential direction. Both free membranes and membranes coupled to 3D elasticity are considered. The discretization of the membrane comes from a Galerkin method using the restriction of 3D basis functions (linear or trilinear) to the surface representing the membrane. In the case of coupling to 3D elasticity, we view the membrane as giving additional stiffness contributions to the standard stiffness matrix resulting from the discretization of the three-dimensional continuum.

    Finite element procedures for computing normals and mean curvature on triangulated surfaces and their use for mesh refinementManuscript (preprint) (Other academic)
    Abstract [en]

    In this paper we consider finite element approaches to computing the mean curvature vector and normal at the vertices of piecewise linear triangulated surfaces. In particular, we adopt a stabilization technique which allows for first order L2-convergence of the mean curvature vector and apply this stabilization technique also to the computation of continuous, recovered, normals using L2-projections of the piecewise constant face normals. Finally, we use our projected normals to define an adaptive mesh refinement approach to geometry resolution where we also employ spline techniques to reconstruct the surface before refinement. We compare or results to previously proposed approaches.

    Modelling and Characterization of Electrostatic Current Noise Induced Mechanically in Wired Wearable Applications2010In: Journal of Electrostatics, ISSN 0304-3886, E-ISSN 1873-5738, Vol. 68, no 1, p. 21-26Article in journal (Refereed)
    Abstract [en]

    By means of statistical modelling and measurement, the triboelectric current noise spectral density is evaluated for shielded cables in body-borne wired network subjected to mechanical stresses. Assuming a shot noise model, an expression for the current spectral density of the noise is derived. The efficiency of the methodology is demonstrated by measuring the triboelectric current noise in two shielded cables subjected to bending. Thereafter the parameters of the noise pulses' waiting time and amplitude probability density functions are extracted from measurement, thus enabling the computation of the current spectral density of the noise induced mechanically in body-borne wired networks.

    Driving Behaviour Profile of Drivers with Autism Spectrum Disorder (ASD)2017In: Journal of autism and developmental disorders, ISSN 0162-3257, E-ISSN 1573-3432, Vol. 47, no 9, p. 2658-2670Article in journal (Refereed)
    Abstract [en]

    The symptomatology of autism spectrum disorder (ASD) can make driving risky, but little is known about the on-road driving behaviour of individuals with ASD. This study assessed and compared the on-road driving performance of drivers with and without ASD, and explored how the symptomatology of ASD hinders or facilitates on-road driving performance. Sixteen drivers with ASD and 21 typically-developed drivers participated in the study. Drivers with ASD underperformed in vehicle manoeuvring, especially at left-turns, right-turns and pedestrian crossings. However, drivers with ASD outperformed the TD group in aspects related to rule-following such as using the indicator at roundabouts and checking for cross-traffic when approaching intersections. Drivers with ASD in the current study presented with a range of capabilities and weaknesses during driving.

    Investigating the driving performance of drivers with and without autism spectrum disorders under complex driving conditions2019In: Disability and Rehabilitation, ISSN 0963-8288, E-ISSN 1464-5165, Vol. 41, no 1, p. 1-8Article in journal (Refereed)
    Abstract [en]

    Purpose: The aim of this study was to investigate the driving performance of drivers with autism spectrum disorders under complex driving conditions.

    Method: Seventeen drivers with autism spectrum disorders and 18 typically developed drivers participated in a driving simulator trial. Prior to the assessment, participants completed the Driving Behaviour Questionnaire and measurements of cognitive and visual-motor ability. The driving simulation involved driving in an urban area with dense traffic and unpredictable events.

    Results: In comparison with the typically developed group, drivers with autism spectrum disorders reported significantly more lapses in driving, committed more mistakes on the driving simulator, and were slower to react in challenging situations, such as driving through intersections with abrupt changes in traffic lights. However, they were also less likely to tailgate other vehicles, as measured by time-to-collision between vehicles, on the driving simulator.

    Conclusions: The performances of licensed drivers with autism spectrum disorders appeared to be safer in respect to car-following distance but were poorer in their response to challenging traffic situations. Driver education for individuals with autism spectrum disorders should focus on quick identification of hazards, prompt execution of responses, and effective allocation of attention to reduce lapses in driving.

    Impact of experience when using the Rapid Upper Limb Assessment to assess postural risk in children using information and communication technologies2014In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 45, no 3, p. 398-405Article in journal (Refereed)
    Abstract [en]

    The Rapid Upper Limb Assessment (RULA) is an observation-based screening tool that has been used to assess postural risks of children in school settings. Studies using eye-tracking technology suggest that visual search strategies are influenced by experience in the task performed. This study investigated if experience in postural risk assessments contributed to differences in outcome scores on the RULA and the visual search strategies utilized. While wearing an eye-tracker, 16 student occupational therapists and 16 experienced occupational therapists used the RULA to assess 11 video scenarios of a child using different mobile information and communication technologies (ICT) in the home environment. No significant differences in RULA outcome scores, and no conclusive differences in visual search strategies between groups were found. RULA can be used as a screening tool for postural risks following a short training session regardless of the assessor's experience in postural risk assessments.

    Exploring feedback loops in the industrialization process: A case study2018In: Procedia Manufacturing, Elsevier, 2018, Vol. 25, p. 169-176Conference paper (Refereed)
    Abstract [en]

    The purpose of this study is to explore the current available practices of feedback loops at different phases in the industrialization process. Although literature highlights the impact of feedback loops for both product and production systems development, there is limited research about how firms utilize the concept of feedback loops in the industrialization process. Based on a case study at a railway component manufacturing company, the paper presents the identified feedback loops and mechanisms that are working well and not working well within the industrialization process. Further, it explains a practical method to improve the current or establish new feedback loops. The paper contributes to the discussion on the application of lean and agile approaches to the industrialization process where feedback loops act as enablers.

    Development projects, stage-gate models, and degree of newness: Examining the correlation from a production perspective2016Conference paper (Refereed)
    Abstract [en]

    Many companies have adopted stage-gate models to manage different types of development projects, which can vary in degree of newness. Currently, there is limited research on how the development projects, stage-gate models and degree of newness are correlated in practice from a production perspective. Based on a case study at a manufacturing company, this paper examines correlations from a production perspective. The results show that the company runs nine types of development projects in production, and uses two forms of stage-gate models. The degree of newness is not addressed in a structured way in production compared to the product development process.

    Konceptframtagning av testinstrument för vattendetektion baserad på MIP2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Water is vital for all life on earth. But it can also be dangerous, even fatal, if it is polluted water. 60 percent of child mortality can directly be deduced to dirty water. Not only developing countries are affected, even in the western world epidemics are breaking out by partake or bathing in dirty/polluted water.

    MIP, Molecularly Imprinted Polymers, is a biosensor technology that can provide faster and more reliable response than the current methods of water analysis. It is also cheaper and due to that more samples can be taken and analyzed. These three variables can reduce the number of patients due to polluted water are detected faster and appoint of necessary measures can be done faster.

    This project searches for the design of an automated sample tool based on MIP techniques. The Concepts must express innovation, high quality and clarity. The instrument should be used both in laboratory and in the field.

    The project has resulted in one concept. The concept is based on the one construction of internal components that is as low height as possible (20 centimeters) and is slightly wider than its depth (40 vs. 30 centimeters). MIP-and NIP containers are located by one of the short side and the battery is near the edge of the front side. The placement is designed to facilitate the loading and exchange.

    The concept answers against all of the demands and two of three wishes.  Also the concept is designed after the further user. The further user has also been involved during the process of the concept design. The development of the concept start with the questions from the brainstorming “What will the user feel when they lay their eyes of the product/instrument and uses is?” The ides and thoughts were to ides sketches. They also used in the evaluation of the same sketches. The most exalting ides develop in to three concepts, and in evaluations, with help from further user, with kansei and discussions. The evaluation showed that one of the concepts was adaptable for further development.

    The concept is smooth and has areas for hold. The user is self looking and searching for the optimal hold. The instrument has none parts that extend from the body and can damage the user. The instruments components that the user need to exchange is placed in a box that by automatic shouts out. The aces to this I controlled by a touch screen. One the touch screen is a hand scanner that is used to lock and unlock the instrument. With a window the process of the analyses is showed. That rice the reliability, lift the functions, give a high-tech and a hero feeling and are fun for the users.

    Abstract [en]

    This study has taken place in Mullsjö at Kongsberg Automotive (KA). The purpose of

    the study was to evaluate how to construct an easy mountable gearknob to the lowest

    cost based on design and functionality by using the techniques of concept generation

    and sifting. The knob is intended to be integrated in a Shift-ByWire shifter and generate

    prototypes through SLS.

    Researchers followed a concept study methodology following an abductive approach,

    to generate an appropriate mechanical design for the gearknob. Concepts were formed

    by a brainstorming process, followed by weighing criteria for the knob and were

    finalised by evaluating the formed concepts using a Pughs Matrix constructed by the

    researches. Relevant literature of mechanical designs processes was reviewed to

    develop the theoretical framework. In addition, data was collected from Kongsberg´s

    computer system and unstructured interviews with employees within certain specific

    areas to gain additional understanding. In cooperation with supervisors, pros and cons

    analysis of cost, functionality and mounting capability were used to enable the

    researchers to draw recommendations for mechanical designs meeting the requirements

    of specification.

    The study resulted in several findings in relation to each research question. In general,

    a gear knob has been constructed using SLS that can be both used for mounting and

    demounting purposes. In addition, this construction met the specification of

    requirements by KA. The Printed Circuit Board (PCB) were constructed using the

    geometrics in the inherent components of the knob. The study further resulted in a

    leather gaiter that were constructed as a link between the dashboard and the knob.

    Results from this study imply that more screws would be used for mounting different

    components in the prototype phase, which will impact the view on criteria for

    forthcoming knobs and their mounting methods. In addition, data collection have also

    shown that snaps in chromium details easily break, which can also further question the

    use of chromium snaps for dismantling purposes.

    Finalised recommendations for the gearknob met the requirements of specification

    since researchers constructed the most simple mounting on the current surface design.

    Researchers conclude that these concepts are applicable and could be presented in a

    following prototype phase. However, if the knob is to be produced, researchers do not

    have enough support regarding the liquid injection moulding, which requires to be

    further considered. Materials will require the design constructed in this study to be

    modified.

    Standardization and modularization of Handling system: Optimization of choice of roller conveyors andloading / unloading tables for beam handling2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This project was commissioned by Ficep S.p.a. and performed in the field of product development with the aim of developing a method for the revision of product architectures in standardized modular configurations.The handling system for profiled beams has a generally well-established structure and technology among all main competitors in the mechanical carpentry sector, for this reason the key to success in the market is the optimization of the components to minimize redundancies and the ability to promptly satisfy the variegated customers’ demands while still keeping competitive prices.The major problem in the layout of these systems is the absence of standard rules or mathematical models, relaying mostly on the empirical norms derived from the experience of the designer, thus generating confusion and variants’ proliferation.For this reason, a standardized and optimized model for generating appropriate configurations according to functional specifics is the final goal of this work.To hit this target the development process has been analysed and reviewed all the way from the customer offer request to final layout definition, passing through the definition of the technical specifics, architecture of the handling system and inner structure of its components.The final result is a configurator that, taking the technical specifications of the client as input data, dynamically calculates the structure of the handling system adjusting even the composition of the elements it is made up of and their position for the layout.As a side project the configurator was used to create a model for cost estimation of the handling system in stages prior to the CAD design of its layout.

    Inköpsavdelningen är en viktig del i företag som ansvarar för att artiklar finns tillgängliga när de behövs. Inköps uppgift är att köpa rätt kvantitet av rätt kvalitet i rätt tidpunkt från rätt leverantör till rätt pris. Detta arbete kan underlättas om tydliga riktlinjer för hur inköpsarbete bör bedrivas finns.

    Swisslog-Accalon AB i Boxholm vill omarbeta sina inköps- och materialplaneringsrutiner, då många av de inköp som görs baseras på inköparens erfarenhet och kunskap om artiklarna samt att många inköp görs mot specifika kranprojekt. Detta har lett till att artiklar i många fall köps utan hänsyn tagen till de mest ekonomiska aspekterna då vanligtvis inga partiformningsmetoder används.

    Syftet med examensarbetet är att skapa ett ramverk för inköp av standardartiklar till företagets kranproduktion, för att inköpsarbetet på företaget ska underlättas och minskas. För att uppfylla syftet med examensarbetet har fyra frågor arbetats fram:

    1. Hur ska standardartiklarna i kranproduktionen klassificeras?
    2. Vad ska ingå i de olika emballagekategorierna?
    3. Vilka är de ekonomiska behovstäckningstiderna för standardartiklarna i kranproduktionen?
    4. Hur ska ramverket användas?

    Relevant empiri har samlats in med metoder som intervjuer och observationer samt att tillgång till nödvändiga dokument och arkivmaterial har erhållits. Empirin som samlats in har analyserats med litteratur inom det aktuella området.

    Resultatet av examensarbetet är ett framarbetat ramverk som beskriver hur inköpsarbetet av företagets standardartiklar till kranproduktion rekommenderas att bedrivas. Dessutom kommer ramverket att underlätta och minska inköpsarbetet, då företaget rekommenderas att styra vissa av artiklarna med enkla och tidseffektiva metoder.

    A Literature Review on Risk Analysis of Production Location Decisions2011Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This report is the result of a master thesis with a focus on risk analysis of production location decisions. The project is a part of “PROLOC-manufacturing footprint during the product’s life cycle”. The main aim of this thesis is to point out how current applicable risk analysis techniques evaluate the risks involved in production location decisions and then underline the most important risks involved in production location decisions and elicit strengths and weaknesses of these methods.A systematic review of literature with a focus on journal papers of risk analysis and production fields is conducted by using the content analysis and coding technique. The current risk analysis techniques identified are failure mode and effects analysis (FMEA), life cycle cost (LCC) analysis, and system based techniques like multiobjective analysis, decision tree analysis, and analytic hierarchy process (AHP). In addition two identified frameworks of foreign direct investment (FDI) and international production are the research fields that have contributed extensively in identifying various risks of production location decisions.Having reviewed the literature, it is realized that majority of companies take a short sighted vision in choosing production location and consider just cost based issues like cheaper raw material and low labour cost in some countries and simply ignore uncertainties that can be sources of political, economic, social, competitive, and seismic risks. Low cost countries are usually situated in politically instable areas that can cause long production halts or expropriation. Political risk is mainly identified in FDI literature and is usually triggered by a political turmoil, coup d’état, or revolution. On the other hand cheap labour does not necessarily mean decrease in costs and might bring about quality issues and damage company prestige among customers which results in time and monetary loss. Currency exchange and inflation in costs often causes the initial forecast and cost analysis go wrong. Supply risks are because of disruption of ties with raw material or part suppliers in home country and might result in risk of misuse by new suppliers or partners. Also the seismic risk is introduced as a separate category of risks of production location decisions which can be considered a matter of more investigation and requires further research.The study also presents a review of strengths and weaknesses of existing risk analysis techniques of production location decisions. The lack of consistency, vagueness of information, unfamiliarity with design to cost concept are among the major weaknesses of risk analysis techniques of production location decisions. The study concludes with the fact that just considering the cost oriented factors like cheap labour and raw material by production companies exposed them to various risk and might make the whole investment in vain. Suggestions for further study on techniques and risks of production location decisions are also proposed.

    Konstruktion rörklammer2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This report describes the development process of a pipe clamp used on exhaust system for cars. It is made based on the manufacturers desire to improve and make the clamp easier to manufacture and to reduce its price to their customers. This should be done either by manufacturing the clamp in one piece without an expensive and work intensive welding process, or by generating ideas of how to develop a brand new type of clamp. Investigating the market for similar products was done to eliminate intrusion of other manufacturers’ patents but also to generate ideas. Making drawings of the many ideas gave a concept of three concepts called existing clamp in one piece, existing clamp by several pieces and innovation solutions. Some of these ideas were investigated further and were 3D modelled in pro-engineer and necessary drawing files were made to be used in the manufacturing of several prototypes. One of the solutions resulted in a prototype that was manufactured by handmade tools and the results of the tests was very positive. The clamp was strong enough to join the pipes together very well without breaking. It was manufactured in one piece and formed in five steps without any welding operations instead of the seven steps, including welding, that is used on the clamp today. The prototype requires 25 % more material and most of it is scrap from the cutting operation.

    Transportkvalitetshöjande åtgärder: en fallstudie vid GP-Last2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This thesis has been done on a haulage contractor company named GP-Last (AB Gustav Perssons Åkeri) and the purpose with the paper was to analyse their traffic from Malmö to Stockholm and leave suggestions on efforts that GP-Last can use to increase their level of transportation quality. This has been done with two main questions, which problem do they have today and which efforts they need to do to solve their problems? Through a case study with interviews as method to collect data it showed that GP-Last had four main problems.

            Not enough information about their freights. The transport planning unit in Malmö doesn’t have the exact delivery address when GP-Last begins to bring in the gods.

            There are no clear routes. The transport planning unit in Malmö doesn’t know how the staffs in Bromma want the trucks to be loaded.

            Inadequate communication between the two sites in Malmö and Bromma. The staffs in Malmö don’t get informed about their mistakes when they load the trucks wrong which results in that the same mistakes are being repeated.

            Lack of attention about how many mistakes that are made. GP-Last have no information about how many mistakes that is being made and how long time it takes to fix the mistakes.    

    The efforts that GP-Last has to make to solve these problem is first to inform Schenker, the company that receives the booking of the freights, about the importance of information about the freights that the unit of transport planning needs. A route list was made in consultation with staff in Bromma that’s going to help the transport planning unit in Malmö. By adopting deviation report when a truck isn’t correctly loaded leads to better communication between the to sites and GP-Last gets good information about how many mistakes that are being made and how long time it takes to fix them.

    A Tentative Framework for Analyzing Integration in Collaborative Manufacturing Network Settings: A case study2005In: Journal of engineering and technology management, ISSN 0923-4748, E-ISSN 1879-1719, Vol. 22, no 1-2, p. 141-158Article in journal (Refereed)
    Abstract [en]

    It is important for small and medium-sized corporations to collaborate in networks in order to develop capacity, capability, and competence to perform product development and become suppliers of complete systems. The purpose of this study is to identify barriers and to develop an analytical framework of inter-organizational collaboration in network settings. In this paper we present a tentative four-dimensional framework in terms of surface of integration, scope of integration, time horizon of integration, and intensity of integration. This framework can be used to analyze how network settings are developed, in terms of structural design of the network, the design of the workflow in collaborative settings, and the aspects of handling the psychological and social boundaries between people.

    Corporate Manufacturing Network: From Hierarchy to Self-Organizing System2006In: The International Journal of Integrated Supply Management, ISSN 1477-5360, E-ISSN 1741-8097, Vol. 2, no 1/2, p. 106-131Article in journal (Refereed)
    Abstract [en]

    In order to handle increased competition small and medium sized companies are collaborating in networks, strategic alliance, or partnership etc. The purpose of this paper is to investigate how direction and accountability is handled in network settings. The authors have performed an extensive case study of one collocated network consisting of four independent companies. This networking has enabled the companies to accept larger customer orders than no single company could handle on their own. It has also made them capable of reaching a high level of adaptation to customer demands regarding development, manufacturing, delivery, and support of the complete product. The high level of inter-company integration has created conditions for the network to develop self-organizing characteristics in terms of autopoietic and sympoietic systems. While the first focuses on the relations between companies within the network, the second focuses on relations between the network and the environment. This self-organizing approach is based on strategic conversation between companies at all organizational levels and participation of managers as well as engineers in the design of inter-and intra-organizational structures and processes. In self-organizing systems direction comes from closeness to customers and strategic dialogue between management and engineers and accountability is a consequence of high level of situational visibility and information exchange on all hierarchical levels among companies in this network.

    Abstract [en]

    A crucial issue in corporate networks is to identify to what extent different strategic and operational decisions need to be coordinated between the involved companies. In this paper we elaborate on the issue of synchronization of information flow based on interconnectivities between companies in order to coordinate a corporate network by the means of DSM, Dependence Structure Matrix. The results show that DSM can be used to identify interconnectivities among actors in a network and to identify which information that needs to be shared between companies in the network.
