    Automated engineer-to-order systems – a task-oriented approach to enable traceability of design rationale2014In: International Journal of Agile Systems and Management, ISSN 1741-9174, Vol. 7, no 3-4, p. 324-347Article in journal (Refereed)
    Abstract [en]

    Mass customization is a rapidly growing business model that enables companies to deliver products with increased customer value. The ability to design and manufacture highly customer adapted products brings a competitive edge to manufacturing companies and is required for business success in some areas. In this paper, an approach for documentation and knowledge management of systems supporting the design and manufacture of customized products is explored. A system’s encapsulated rules and models have to be updated and refined due to shifting prerequisite and both the system and the solutions generated for a single specification will change over time. These changes affect product management and the ability to meet legislation and customers’ requirements regarding documentation and traceability, as well as the company’s ability to provide services, maintenance and supply spare parts. This work addresses this challenge and introduces a concept with required functionality for capturing, structuring, searching, retrieving, viewing, and editing a system’s embedded information and knowledge. The concept has been developed and applied to a real case in collaboration with a company acting as a sub-supplier in the automotive industry. The objective was to enable and facilitate maintenance and updating of existing system and support the reuse of functions and system encapsulated generic design descriptions in the development of future systems.

    Computer Supported Quotation Preparation of Turned Components2012Conference paper (Other academic)
    Abstract [en]

    The quotation preparation in the manufacturing industry is very important. From a subcontractor view, it is initiated by a customer request for quotation and precedes the order preparation where detailed manufacturing and cost information are generated. Customers are continuously seeking for lower bids and cost reduction and despite the lack of detailed information a fixed price has to be set. Commonly, subcontractors are also acting on a market where the competition of staying in business and submitting a winning bid is intense and the result of the quotation process has a direct influence on the final business success. Hence, it is essential to enable quotations to be based on a higher level of detailed information and introduce support to increase the efficiency in quotation preparation. The purpose of this work is to investigate, explore, and develop a computerized method, i.e. an application system, to support the process planning and cost estimation in the quotation process. The main objective is to reveal concepts and principles to support application system development and utilization. The results are based on the experiences from a case study at a subcontractor of turned components.

    Decision Support in the Quotation Process of Engineered-to-order Products2012In: Advanced Engineering Informatics, ISSN 1474-0346, E-ISSN 1873-5320, Vol. 26, no 1, p. 66-79Article in journal (Refereed)
    Abstract [en]

    Sub-suppliers acting in the supply chain of the car industry have to adopt a strategy of products customization to be at the competitive edge. This is caused by the diversity of client’s requirements that entails customer engineered products with a high level of variety. A business strategy based on engineered-to-order products requires systems for efficient generation of product variants. This also includes a need of decision support in the order preparation process as well as in the quotation preparation process. Decision support that gives access to detailed and accurate information in the quotation preparation enables a high level of product adaptation while ensuring company efficiency. By the introduction of a design automation system, this can be achieved. However, means to manage different application domains, projects, task knowledge and design information are required together with a possibility to perform detailed analyses on the system generated information. The objective of this work is to contribute in that area. Initially, a number of success criteria were identified and explorative work was conducted for the purpose to develop a conceptual model and principles that an application system would reside upon. The result is a framework consisting of an information model and underlying principles to be used when developing a design automation system for quotation preparation. A system founded on the framework supports management and analysis of quotations and product variants. The functionality and usefulness has been demonstrated and validated by a system implementation developed in collaboration with an industry partner.

    Supporting Management and Analysis of Quotations in a Design Automation Approach to Customization2010In: New World Situation - New Directions in Concurrent Engineering: Proceedings of the 17th ISPE International Conference on Concurrent Engineering, 6 - 10 September, 2010, Cracow, Poland, 2010 / [ed] J. Pokojski, S. Fukuda, & J. Salwiński, 2010, p. 401-409Conference paper (Refereed)
    Abstract [en]

    A business strategy based on customized products with a high level of variety requires systems for efficient generation of product variants. An area identified in near collaboration with five industrial partners that has not been subject for extensive research is how to support management of different application domains, projects, task knowledge and design information together with the possibility to perform detailed analyses on the data generated by a design automation system implementation. Initially, a number of success criteria were identified and the functionality of a database was perceived as a promising approach. Explorative work was conducted for the purpose to reveal the conceptual model and the principles that a system would reside upon. The work has resulted in an approach, consisting of an information model and underlying principles, presented in this paper to be used when developing a design automation system for quotation preparation. The functionality and usefulness has been demonstrated and validated by a system implementation developed in collaboration with an industry partner. It can be concluded that a system founded on the presented approach supports management and analysis of quotations and product variants.

    Supporting Management and Maintenance of Manufacturing Knowledge in Design Automation Systems2008In: Advanced Engineering Informatics, ISSN 1474-0346, E-ISSN 1873-5320, Vol. 22, no 4, p. 445-456Article in journal (Refereed)
    Abstract [en]

    Many companies base their business strategy on customized products. To enable a high level of product adaptation in an engineer-to-order approach companies invest time and resources to develop design automation systems. Initially, when implementing a design automation system, the focus is on successfully developing a system that generates design variants based on different customer specifications (i.e. the execution of system embedded knowledge and system output). However, in the long run, two important aspects are the management and maintenance of the knowledge that governs the designs. Further, the increasing emphasis on deploying a holistic view of a product’s properties and functions implies an increasing number of life-cycle requirements. The knowledge to adapt the product to fulfil these requirements should also be used and consequently incorporated into the knowledge-base, allowing for correct decisions to be made. In a system for automated variant design, the implications on the product of these life-cycle requirements have to be expressed as algorithms, production rules and/or computational statements to be intertwined with the design calculations. The number of requirements can be significantly large, and the knowledge scattered over different application systems used for the realisation of the design automation system. This makes it difficult to manage and maintain the system as the product life-cycle environment changes and evolves. In this article, the focus is on the requirements related to manufacturing. For that, an approach for the modelling of manufacturing requirements, supporting both knowledge execution and information management, in systems for automated variant design is introduced. The approach has been applied and refined when developing a design automation system in cooperation with a company to demonstrate and verify the approach’s usability.

    Design Platform - A Coherent Model for Management and Use of Mixed Design Assets2017In: Transdisciplinary Engineering: A Paradigm Shift: Proceedings of the 24th ISPE Inc. International Conference on Transdisciplinary Engineering / [ed] C. H. Chen, A. C. Trappey, M. Peruzzini, J. Stjepandić, & N. Wognum, IOS Press, 2017, no 3-4, p. 703-712Conference paper (Refereed)
    Abstract [en]

    For many companies, it is a challenge to balance product variety and cost, i.e. external and internal efficiency. Product platforms has been the dominant solution for a business targeting mass-customization. The main idea is to dived the product into modules that can be shared among different product variants. This has been a success on the consumer market, however, many manufacturing companies are engineer-to-order (ETO) oriented, such as original equipment suppliers (OES). They design a unique solution, often in close collaboration with other companies, based on different product concepts and/or core technologies. For these companies, there is a strategic need for a platform model influenced by the principles of masscustomization, although, not limited to only include modules. In this work, a novel platform model, called Design Platform is described. The model has been developed and applied in cooperation with four companies. The Design Platform provides a coherent environment for management of heterogeneous design assets to be used in product development and supports an improved ability to master fluctuating requirements and systematic introduction of new technologies.

    Abstract [en]

    Product platforms has been a successful enabler for efficient mass customization. However, they cannot fully support suppliers working in an engineer-to-order business environment. This work identifies the need and scope of a different platform model that supports customization and management of fluctuating requirements. A novel plaform model is introduced entitled Design Platform. The model is based on the current state and future target condition at four companies. The model provides a coherent environment for heterogeneous design assets to be used in product development.

    Knowledge Object - a Concept for Task Modelling Supporting Design Automation2014In: Advances in Transdisciplinary Engineering: Moving Integrated Product Development to Service Clouds in the Global Economy / [ed] Jianzhong Cha, Shuo-Yan Chou, Josip Stjepandić, Richard Curran, Wensheng Xu, Amsterdam: IOS Press, 2014, p. 192-203Conference paper (Refereed)
    Abstract [en]

    The ability to design and manufacture highly customer adapted products brings a competitive edge to manufacturing companies acting on a business-to-business market as suppliers to OEMs. A vital means for success in quotation and order preparation is advanced system support in design, process planning and cost estimation based upon the automation of engineering tasks. A design automation system encapsulates these tasks which are to be executed for specific customer specifications in a sequence specified either by a predefined order or resolved by an inference mechanism in run-time. Commonly, the development of a design automation system is an iterative process alternating between a top-down and a bottom-up approaches. An overall strategy is a necessity for successful system development, however, to successfully define the tasks, retrace all the necessary knowledge and to close gaps in both the tasks and the knowledge definitions require a complete and detailed understanding of the specific domain. In this paper, the concept of Knowledge Object is described together with examples of its use in both the development and system realization of design automation systems enabling product customization. The concept has shown to be useful for modelling of design processes, tasks, and engineering knowledge as well as in system development and realization. It also supports traceability and understanding by relations to other concepts describing associated requirements and design rational.

    Abstract [en]

    Many manufacturing companies are suppliers that deliver unique solutions to different business customers. Intense quotation work, with a high demand on accuracy and quick response, and development projects executed in close collaboration with customers and other actors characterize these companies. The projects can run for years or a few weeks depending on the business. Changes of requirements are frequent and technology development required for improved functionality, sustainability and competitiveness. The use of a product platform has been acknowledged as a strategic enabler for product family development and mass customization. However, companies struggle with adopting the common platform approach building upon pre-defined modules and components as it constraints the fulfilment of unique customer requirements and the introduction of new technology at high pace. This work reports the results from case studies conducted in collaboration with four companies. They are in many ways different but face the same challenges when it comes to customization, fluctuating requirements and need of high pace in technology advancement. The focus of this paper is on their initial states; including how they work with their product concept before the customer entry point, the work that is initiated when an order is accepted, the character of requirements and the adoption of product platforms. Criteria on, and identification of, new platforms models, termed Design Assets, are presented followed by a mapping to the Design Platform concept pointing out areas upcoming work, both scientifically and at the companies.

    Supporting Traceability of Design Rationale in an Automated Engineer-To-Order Business Model2012In: DS 70: Proceedings of DESIGN 2012, the 12th International Design Conference, Dubrovnik, Croatia / [ed] Marjanovic Dorian, Storga Mario, Pavkovic Neven, Bojcetic Nenad, 2012, p. 1425-1434Conference paper (Refereed)
    Abstract [en]

    The ability to efficiently and quickly design and manufacture highly customized product can provide a competitive advantage for companies acting on a market with shifting customer demands. A business model based on highly customized product requires advanced application systems for automating the work of generating product variants based on different customer specification. The establishment of a system for automated design and production preparation is a significant investment in time and money and is expected to give revenues over many years. To maintain a design automation system’s usefulness over time, frequent updating of design rules and execution control will normally become a necessity. Reuse of the system encapsulated generic product family descriptions when developing a new product family is also perceived to significantly increase the efficiency in system development. The scope and the purpose of this research originate from industrial problems and needs which have been identified within research projects carried out in near collaboration with industrial partners. New concepts, perceived as prescriptive models, are in this work introduced, evaluated, and refined which is in accordance with the design modelling approach [Duffy, Andreasen, 1995]. The focus of this paper is a case study carried out at a company with long experience of systems for automated variant design. The main objective is to provide a system foundation for modelling and management of product knowledge in design automation systems to support reuse, expansion and maintenance.

    Produktkalkylering på ett Värmebehandlingsföretag2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this report is performed on behalf of a Heat Treatment Company. The commission is to create a calculation model of their machines, BA1 and BA2. In the commission it is included to put together a line utilization follow-up for these plants. The calculation model will be used for pricing towards customers. At present, the pricing can be a bit unfair when certain products is more man intensive and requires more treatment time than others because of the product design.

    Today the company’s prices only considering harden deep, harden method and weight. The bigger an order is in weight, the cheaper per kilo it becomes. No or little consideration is taken to product design or that light and bulky products takes longer time to treat. Neither that certain products requires more manual work is considered.

    Since the products requires different amount of treatment time we’ve divided them into three different classes. These are described in chapter three and are based on how manageable and how man intensive the products are. It also shows that consideration must be taken to which treatment method that is used, which can be divided into hardening and case-hardening. By using the equivalent method we considered the resource used by each product.

    The follow-up for BA1 and BA2 regarding the utilization shows that they have a rather poor utilization; it’s between 3 % and 67 % for the different products classes.

    Our calculation shows that considerations must be taken to treatment time, that partial depend on product design and treatment methods. The result also shows that products of certain classes today have a higher unit cost than current pricing. This mostly concerns products associated to class C.

    Ställtidsreducering med hjälp av SMED i pressgjuterianläggningar2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.

    The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.

    Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis. Meetings have been held with Husqvarna AB about their expected earnings on there new investment.

    The work with analyzing die changeovers resulted in following suggestions of improvement:

    • Manuals of adjustments to the sprayer

    • Rapid couplings to the warmth- and cooling hoses

    • Eliminating the work of adjustment when changing the ladle

    • Introduced a combined spanner- torque wrench

    • Manuals to the mechanical lock

    The total theoretical improvement of these measures, along with routines for making outside exchange of die before the machine was shut downed, became a reduction of time spent on die changeover with 60%, from 167 minutes to 66 minutes. That corresponds to a capacity/possible sale increase with 3030 SEK/changeover.

    The conclusion of this survey is that investing in new equipment is not the best way to gain capacity. Better results can be made just by working with die changeovers on the present machines. If a company has worked with reducing time spent on die changeovers before, and is about to replace an old machine, it could be a cause to invest in new technological details to make the work with die changeovers less complicated.

    Inoculation and its effect on primary solidification structure of hypoeutectic grey cast iron2010In: International Journal of Cast Metals Research, ISSN 1364-0461, E-ISSN 1743-1336, Vol. 23, no 2, p. 124-129Article in journal (Refereed)
    Abstract [en]

    The solidification of grey cast iron is controlled by the addition of inoculants. This is done in order to provide nucleation sites and hence facilitate the formation of eutectic cells and decrease the degree of undercooling. The number of eutectic cells and the graphite morphology affect the final properties of the casting. Preceding the nucleation of graphite and the eutectic cells is the nucleation of the primary austenite. It was found that the addition of inoculants also influences the primarysolidification. The largest effect on the primary dendrites is obtained by inoculation using pure ironpowder. It was also shown how the columnar to equiaxed transition (CET) depends on the number ofequiaxed dendrites per unit volume. In addition, the primary structure was found to influence the eutectic solidification. The relationship between the secondary dendrite arm spacing and the eutectic cell size was found to correlate well with the work of others.

    Separate to integrate the task as a whole in work meetings?: Two types of learning hindering each other – the duality between execution and development of the same task2016Conference paper (Refereed)
    Abstract [en]

    Many organizations have difficulties finding the necessary balance between execution and development of the same task. The phenomenon causes conflicting demands on an organization’s resources and can be identified as ambidexterity. In practice, the ambidexterity dilemma has been seen in the discussion of work meetings, which in some situations not are as effective as expected. Even if there has been a lot of research on the ambidexterity dilemma there are still a lack of studies on internal processes during interactions in work meetings (micro practices) according to different tasks. The purpose of this article is to explore how interaction during work meetings can be organized and managed in order to improve work meetings and stimulate learning for ambidexterity when dealing with the duality between the execution and development of a task. The overall question to be answered is – How can the execution and development of a task become an integrated part of the learning processes of individuals and groups? As theoretical framework Dewey’s and Ellströms theories of learning is used as a filter when analysing the interaction in video filmed meeting in an industry. The results indicate that execution and development are two different, equally important logics, in agreement with previous research. This study indicates that the two logics might need to be separated in time and space to become integrated in the minds of individuals and groups. The duality between execution and development becomes a whole when the same people are dealing with both dimensions of the task. The way an organization can meet human power is to ensure that people in the organization get involved in both execution and development but at different times and in different spaces to avoid the two logics interfering with each other.

    Kundcentrerade miljöåtgärder - En studie av Pan Nordic Logistics kunders krav på miljövänliga transporter: Customer centered environmental measures - A study of Pan Nordic Logistics customers demand for environment-friendly transport2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    Traditional product features such as price, quality and supply service have been extended and nowadays includes environmental aspects as well. It raises new and increasing demands on haulier companies. The transport sector is responsible for a large part of the pollutants causing today’s environmental problems. The business is being closely monitored and to operate environmental friendly is seen as one of the most important elements for the industry’s future development. Haulier companies must not only meet the restrictions of the government, but also respond to the customers’ demands on

    environmental performance.

    The aim of the study is to review the environmental demands of PNLs present customers and what they think their demands will look like in three years time. The scope of the survey is two-fold. The study will partly review if the changing environmental aspects can impact on supply service and price; and partly investigate the importance of an environmental certification. To reach the aim of the study qualitative interviews have been carried out with nine of PNLs present customers. The choice of customers has been made to represent

    an overall picture of PNLs customer portfolio.

    The study concluded that supply service and price is more important than environmental aspects today. The customers are prone to compromise on delivery time and price to the advantage of the environment. But it can not cost too much or take too long, and there must be a possible choice of transport.

    There are today no expressed environmental demands on transport, but the conclusion is that it is only a matter of time before they will prevail. The results prove that environmental issues are estimated to be fundamental for hauliers in the future. It is seen as a competitive advantage to be at the leading edge of offering green transportation alternatives.

    It is considered important today that hauliers pursue environmental issues aggressively. A certification according to ISO or other environmental management systems is considered less important. The results show that environmental management systems and an operative environmental framework will increase in importance in the future when choosing between hauliers.

    Exploring opportunities for moral disengagement in codes of conduct from the textile industry2018In: World Review of Intermodal Transportation Research (WRITR), ISSN 1749-4729, E-ISSN 1749-4737, Vol. 7, no 4, p. 371-389Article in journal (Refereed)
    Abstract [en]

    The purpose of this research is to assess how codes of conducts are outlined and formulated in relation to moral disengagement along the supply chain. The research is focused on the idea that supply chain structure may reduce the actors' sense of moral responsibility for the actions and impacts of the supply chain on workers and environment. The research has been conducted as a case study including Swedish firms in the textile industry. The research has used secondary data from codes of conducts. The findings show that codes of conduct do not cover all supply chain practices linked with moral disengagement. This does not cause immoral behaviour as such, but might cause moral disengagement. Supply chain research needs to focus on what should be included in codes of conduct and other ethical guidelines, so as to reduce the risk of immoral behaviour. In order to reduce the likelihood for moral disengagement, there are several supply chain practices that should be included in codes of conduct, such as power asymmetry, managerial support, and incentives.

    The Process of Responsibility, Decoupling Point, and Disengagement of Moral and Social Responsibility in Supply Chains: Empirical Findings and Prescriptive Thoughts2016In: Journal of Business Ethics, ISSN 0167-4544, E-ISSN 1573-0697, Vol. 134, no 2, p. 281-298Article in journal (Refereed)
    Abstract [en]

    The aim of the paper is to explore and assess the process of responsibility, decoupling point, and disengagement of moral responsibility, in combination with business sustainability (BSus) in supply chains. The research is based on a qualitative approach consisting of two multifaceted case studies, each including multiple case companies and different empirical research characteristics, and a review of BSus in supply chain literature. The case studies apply moral disengagement (MDis) to propose how moral responsibility can deteriorate in supply chains, and the literature review identifies elements of BSus in supply chain management (SCM). The contribution of this paper is to compare these two research streams and evaluate the efficacy of the concepts proposed in the case studies. Through this study, BSus gains an entirely different and complementary toolkit which should facilitate further and more effective research in SCM. The theory of MDis also provides a foundation for reinforcing explanatory and prescriptive aspects of ‘best practices’ in the SCM literature. The findings also establish a basis for organizing and monitoring supply chains so as to improve BSus efforts. Considering moral responsibility as a flow this research explains why and how certain practices may impede BSus efforts in supply chains. Original and/or innovative outcomes include explanatory and prescriptive insights that emerge from a combination of empirical findings from two case studies, including seven companies and a framework for improving BSus management in supply chains, based on a typology of moral disengagement.

    Effektiv partiformning: analys och tillämpning på Uppåkra Mekaniska AB2006Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    This paper is the result of a case study conducted at Uppåkra Mekaniska AB during the spring of 2006. The task that was presented by Uppåkra was to develop a basis for a decision for the planning activities at the company, so that in the future they can create lot-sizes which are based upon a total cost perspective. Total cost in regards to lot-sizing is defined as the sum of the administrative reordering costs and warehousing cost per stock keeping unit.

    To collect data a series of interviews and observations were conducted. This data was then used during the lot-sizing simulation and analysis. The 15 units that the simulation was conducted on were grouped into three item classes depending how many different machine setups they required during the production process. Class A contained items which resulted in only one machine setup; where as those items in Class B had several different setups. Class C represents items without any machine setups, but requires shorter preparation for assembly. In the simulations the Wilson’s formula, Economic Part Period (EPP) and Least Cost method (LC) were compared with the lot-sizing model currently used by Uppåkra.

    The simulation results showed that there is a large potential to reduce the cost of lot-sizing by using the Wilson’s formula instead of the current model. For the 15 units simulated in this study, there was the potential to reduce costs by 5000SEK per unit yearly.

    Ergonomic improvement on Husqvarna trimmer2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Injuries caused by vibrations are a common problem that can emerge from daily exposure when using handheld power tools like grass trimmers. These are often permanent and can’t be cured. Rotations caused by the motor create vibrations where unbalance of the trimmer line can create high amplitudes of vibrations. This report studies how these vibrations affect the trimmer and what solutions that can dampen them with the help of material and mechanical design. By using experimental tests and theoretical evidence it is possible to show how vibrations emerge. These tests proved to be useful when concepts and prototypes were created.

    Studie och förbättring av Saab Training & Simulations projektmodell och arbetssätt2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this bachelor thesis was to examine risks in Saab Training & Simulations project model and the way they execute projects to present an improvement proposal. The study was executed through quantitative and qualitative data gathering in form of interviews and collecting of project reports. The result showed differences between the project model and the execution. The risks were mainly connected to the execution and could be summarized in to three problem areas, manager dependent project management that creates confusion and uncertainty in the line organization and project groups, communication faults during the execution resulting in unnecessary purchases and that the projects show a tendency of needing more resources at the end of the project due to postponed milestones. Based on the findings an extensive literature review treating general project management, project model and methods as concurrent engineering and agile methods were made. After further analysis, an improvement proposal could be formed, however since Saabs project model were found adequate with several parallel and time effective element the improvements are focused towards the way of working in four hands-on suggestions.

    • Clear assignation of responsibility - A clearer assignation of responsibility reduces the risks associated with ambiguity and misunderstandings, as a result of person dependent project management. 

    • Project pulse - Adoption of pulse meetings in the project groups.

    • Increase customer contact - By increasing the contact and integration with the customer could it be assured that their demands are meet even though it is not known during the sale.

    • Design for manufacturing and assembly - Clearer guidelines and a way of working and cooperating internally during the product realization could decrease the risk of unnecessary purchases.

    Affective surface engineering- using soft and hard metrologhy to measure the sensation and perception in surface properties2018In: Proceedings of NordDesign: Design in the Era of Digitalization, NordDesign 2018, Linköping: The Design Society, 2018Conference paper (Refereed)
    Abstract [en]

    New surface treatments, novel material developments, and improved quality control procedures and advanced metrology instrumentation create a possibility to further develop competitiveness by the selection of “optimal” surface features”, to a product. The customers first apprehension of a product and the creation of desire is a very complex, but tempting process to learn more about. The interaction between the added quantitative- and the qualitative direct impressions with the customers known and unknown functional demands, social background, and expectations results in sensation and perception, partly possible to quantify and to great extent impossible to pin-down as numbers. Customer sensation and perception are much about psychological factors. There has been a strong industrial- and academic need and interest for methods and tools to quantify and linking product properties to the human response but a lack of studies of the impact of surfaces. This paper aims to introduce a novel approach to develop and join a human sensoric inspired metrology frame-work with qualitative gradings of apprehended impressions of products with varying surface properties. The aim is to establish the metrology framework to link measurable- and unmeasurable impressions of product surfaces to customer FEELING as exemplified by a set of industrial applications. In conclusions of the study, future research in Soft metrology is proposed to allow understanding and modelling of product perception and sensations in combination with a development of the Kansei Surface Engineering methodology and software tools.

    Abstract [en]

    This report presents a thesis done in the field of mechanical engineering with a focus on product development and design. The work was done together with Kongsberg Automotive AB in Mullsjö. The company wants to investigate the push button solutions available on the market today and the solutions that seem promising for the future. The purpose of this thesis is to examine what the user perceives as quality and define which solution the company should use in future products.

    To make the subject less about an abstract feeling of quality a method for interviewing end users was created. This allowed their feelings about good and bad characteristics to be concretized to statistical data about characteristics and buttons tested in the study.

    These statistics where then used in a product development process to create concepts from ideas. With support from an experienced professional a direction was set to create prototypes built around existing switches matching the results of the interview based study.

    The result is a number of concepts for solutions, as well as 3D-printed prototypes of the more promising solutions followed by advice on which direction future research in the area should be headed.

    The task was solved with several well documented methods such as Kano. With these methods, the market has been reviewed, user comments about quality have been collected and analyzed and new concepts has been created to accompany the coming trend and meet user demands.

    China's aircraft industry: collaboration and technology transfer - the case of Airbus2010In: International Journal of Technology Transfer and Commercialisation (IJTTC), ISSN 1470-6075 (print) 1741-5284 (Online), Vol. 9, no 4, p. 306-325Article in journal (Refereed)
    Abstract [en]

    China has moved a long way in economic and industrial development during the last decades and has developed into a global player in many industries. With increased knowledge in high-technology industries, China has ambitions to move into sectors that necessitate a high level of research and development, such as the aerospace industry. China is now in the process of establishing a modern aircraft industry based on domestic efforts as well as agreements with foreign partners in the manufacturing of complete aircraft. This paper analyzes what measures have been taken by Airbus in the form of technology transfer and other supportive measures to strengthen its position in the Chinese market. The findings conclude that Airbus’ transfer should be looked upon as a broad spectrum of technology and knowledge transfer, which include aircraft manufacturing technology, as well as cabin crew training centre, establishment of a warehouse and suppliers ”village”, an engineering centre, maintenance and various service functions.

    Abstract [en]

    The paper investigates in what way and to what extent Taiwan has been able to develop a commercial aerospace industry and the formation of an internationally competitive supplier system, i.e. high-tech cluster. The development of such an industry has been much more difficult than expected. Since the late 1990s there have been signs that a supplier system is under development, but there are great challenges ahead, amid a fierce international competition.

    Abstract [en]

    South Korea and Taiwan are two of the most prominent examples of newly industrializing economies which have been remarkably successful during the last three decades. This paper gives an overview of South Koreas’s and Taiwan’s development and innovation policies, and compare between these two economies’ main strengths and weaknesses regarding innovation and technology. Conclusions drawn show that there are similiarities as well as differences in the innovation systems in the two economies. The role of the state has been fundamental in South Korea’s and Taiwan’s economic and industrial development. In South Korea there has been very strong ties between the chaebols and the state. The chaebols have been the greatest strenght of Korea’s innovation system, while the there is a lack of interplay between universities and the private sector. The role of the state in Taiwan has concentraded more on creating supporting institutions that have focused on building human resources, acquiring technology from abroad, creating science and technology capacities. In Taiwan it seems that there are more developed mechanisms to transfer research results from public research establishments to the industry, especially SMEs. The industrial policy in Taiwan has supported a rather close cooperation between industry and the state and increased connection between universities and the state. The weakest links seem to be between universities and the industry.

    CUSTOMER FOCUSED DESIGN: development of a new concept for Nimbus Boats2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This Master thesis project was made in collaboration with Nimbus Boats, who manufacture leisure boats for sports and cruising. The aim was from a customer focused approach develop a new 27 feet motorboat. The purpose was to investigate how a new boat concept could look like, especially from a customer perspective and reflect on the design process. The target was to develop an innovative, functional and aesthetical pleasing concept with a focus on the near future market.

    This project is theoretically based on the design process, design thinking theory and design methods. The product development process relied heavily on market research as unstructured interviews, semi-structured interviews and a big survey was employed early in the process. A long with background analysis the design process also included methods like: the design brief, project planning, stakeholder analysis, ergonomics, competitor analysis, benchmarking, functional analysis, target group/ personas, image board, brainstorming, semantics, sketching, evaluation methods, CAD-modeling and finally physical model building. The aim was to develop a very social, comfortable and secure boat that can deliver the ultimate feeling of freedom and experience of nature.

    The result of the design process was a rendered model and a physical model in scale 1:20 that hopefully fulfilled the purpose well. The concept has a modern, dynamic, vigorous and sporty look with large social areas.

    A Top-Down Rationalisation in Mail Delivery – Short-term Outcomes2002Conference paper (Other academic)
    Abstract [en]

    The Swedish Post Office is undergoing large-scale restructuring, including outsourcing of the mail service division to an independent market driven organisation. As a consequence of exposure to competition, the local delivery offices were rationalised by introducing a new working concept called “Best Method”. It was a top-down change process that included downsizing the personnel, more standardisation of working and formalisation of delivery time. The changes have influencedthe postmen’s working conditions in several ways and they perceive a greater workload. This paper aims to identify the factors that contribute to the increased workload and work intensification due to the rationalisation inherent in the new working concept. The findings emerge from an evaluative investigation conducted during autumn 2001 at fifteen local delivery offices in different parts ofSweden. It was carried out by an independent research team in industrial ergonomics through participant observation, 60 in-depth interviews anda questionnaire answered by 524 postal personnel, mainly postmen. Several factors contributing to the increased workload and work intensification have been identified, such as a faster work pace and greater physical workload, less flexibility forthe individual, insufficient participation, shortcomings and contradictions in the new working concept, deficient strategic planning and systems thinking, and a somewhat indistinct organisational philosophy. Further research activities are now taking place and an intervention study is in the planning stage.

    Perceived Participation - a Key Factor for Successful Implementation of a New Working Concept2002Conference paper (Other academic)
    Abstract [en]

    The Swedish Post Office is undergoing large-scale restructuring including outsourcing of the mail service division to an independent market driven organisation. As a consequence of exposure to competition, the local delivery offices were rationalised by introducing a new working concept called “Best Method”. The implementation process varied substantially in terms of success at the local delivery offices. The aim of this paper is to identify factors crucial to the success of the process. The findings emerge from a study performed during autumn 2001 at fifteen local delivery offices in different parts of Sweden. It was carried out by participant observation, 60 in-depth interviews and a questionnaire answered by 524 postal personnel. A number of factors related to a successful implementation process have been identified as vital, such as participation, local and central managerial support and local adaptation of a managerial tool. In order to arrive at a more participative approach, an infrastructure is suggested that will improve information flow and communication both horizontally and vertically in the organisation. This calls for further research activities, which are planned in a second phase.

    Lidingörapporten I: en utvärdering i närtid av Brevbärarnas Arbetssituation2004Report (Other academic)
    Abstract [sv]

    Utvärderingen har utförts på uppdrag av Servicenätet Leverans, Posten av en forskargrupp vid Avdelningen för Industriell arbetsvetenskap, inom forskningsområdet Kvalitet, Människa, Teknik vid Linköpings universitet. Det övergripande syftet har varit att medverka till utveckling, implementering samt utvärdering av åtgärder avsedda att förbättra brevbärarnas arbetssituation (BAS) enligt Postens målsättning. 

    Syftet har närmare bestämt varit att ge en samlad bild av de olika BAS-åtgärderna i tre avseenden:

    1. dels att utvärdera effekten av förbättringsåtgärder för främjande av brevbärarnas arbetssituation,
    2. dels att utvärdera hur själva införandeprocessen har fungerat samt,
    3. att dra lärdomar inför implementering av förbättringsåtgärderna vid övriga postutdelningskontor i landet.

    Arbetet med att ta fram konkreta lösningar påbörjades i fyra delprojekt inom BAS II våren 2003 och avrapporterades under tidig höst 2003. Samtidigt startade förberedelser för att utvärdera helhetseffekten från samtliga åtgärdsförslag enligt BAS II på ett ”pilotkontor”, där valet föll på ett utdelningskontor på Lidingö. 

    En projektgrupp med representanter för personalen på utdelningskontoret på Lidingö, medlemmar från BAS-projekten samt forskargruppen planerade tillsammans hur de olika förbättringsåtgärderna skulle införas och utvärderas.

     De övergripande förbättringsåtgärderna har huvudsakligen gällt:

    • Införande av en Manual för organisation av inomhusarbetet
    • Införande av ny märkning av kamfacken
    • Införande av ny arbetsbelysning vid kamfacken
    • Utbildning i arbetsteknik

    Dessutom har en test av en motordriven konstruktion för höj- och sänkbarhet av kamfacken utförts och utvärderats.

    Implementeringen och utvärderingen har genomförts på Lidingökontoret under perioden oktober 2003 till och med maj 2004. Efter deltagande observation av forskargruppen på utdelningskontoret har 35 brevbärare deltagit genom att dels besvara fem delenkäter och dels medverka i fyra gruppintervjuer. Intervjuer har även genomförts med de två teamledarna, dirigenten samt postcenterschefen. Utvärderingen av förändringsarbetet handlar såväl om de upplevda resultaten som om hur själva förändringsarbetet eller införandeprocessen har fungerat och lärdomar som kan dras av detta.

    Resultaten visar att effekterna av samtliga förbättringsåtgärder enligt BAS-projekten generellt har upplevts mycket positivt av såväl brevbärare som kontorsledningen. Förbättringen av belysning och märkning är de åtgärder som upplevts ge en omedelbar och påtaglig förbättring och därför har varit lättare att utvärdera på kort sikt.

    Arbetet med Manualen kräver däremot organisatoriska förändringar av arbetsprocesserna på utdelningskontoret. Detta kräver ett längre tidsperspektiv för utvärdering av resultaten. Detsamma gäller utbildningen i arbetsteknik som kräver en förändring i arbetssätt och därmed en beteendeförändring. Det tar tid att lära in nya sätt att arbeta och en sådan utbildningsinsats kräver också en utvärdering på längre sikt för att förbättringar skall gå att urskilja.

    När det gäller upplevelsen av själva införandeprocessen upplevde brevbärarna generellt att den haft vissa brister även om åsikterna varierade. Det har i viss mån påverkat deras positiva upplevelser av förbättringsåtgärderna i negativ riktning.

    I ett pilotprojekts natur ligger att man vill dra lärdomar inför framtiden, i det här fallet lärdomar som andra postutdeningskontor kan dra nytta av vid införandet av BAS-åtgärderna men också lärdomar för personer som har ledningsansvar i projekt- och förändringsarbete. Medarbetarna på Lidingökontoret har generöst delat med sig av sina erfarenheter och dessa ligger till grund för de råd som ges i det avslutande avsnittet inför det fortsatta implementeringsarbetet av BAS-åtgärderna på övriga postutdeningskontor i landet.

    Knowledge integration with customers in collaborative product development project2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Driven by rapid technological developments, greater customer expectations, and increased product complexity,product development processes increasingly rely on the integration of dispersed specialist knowledge.Consequently, many industrial firms are changing the way they approach product development. Productdevelopment increasingly relies on knowledge integration across firm boundaries. Customers are one of the mostindispensable sources of knowledge, and their knowledge needs to be integrated during product development.However, little is known about the processes and mechanisms used to integrate customer knowledge in productdevelopment.Therefore, firms must devise processes and mechanisms that support knowledge integration withcustomers. This thesis aims to investigate knowledge integration with customers in collaborative productdevelopment.

    The work described in this thesis combines a case study with a survey approach. More specifically, five casestudies were conducted at three industrial manufacturing firms. Data were collected in 46 interviews, along withinformal discussions, workshops, and secondary material. The case studies revealed the role of knowledgeintegration, knowledge integration mechanisms, and the importance of contextual factors related to the customer’stechnical capability, and the locus of initiative for the product development project. A cross-sectional survey wasperformed in order to ascertain the role of knowledge integration and its effect on innovation performance and theeffect of firms and customers’ technical capability and locus of initiative on knowledge integration withcustomers. The survey study generated 216 responses from firms operating in the Swedish manufacturingindustry.

    This thesis consists of a compiled summary and five appended papers. The results in these provide the basis formodelling knowledge integration with customers. The findings confirm that integrating knowledge withcustomers in product development is associated with better innovation performance. Further, the results point tothe dynamic characteristics of knowledge integration in product development processes. More specifically, firmstend to apply different combinations of mechanisms in different phases, depending on the intended content of theknowledge contribution of the customer and the requirements of each phase in the development process. Inaddition, the degree of technical capability, internal integration capability, and locus of initiative are importantfactors influencing knowledge integration processes. This thesis sheds new light on collaborative productdevelopment with customers by demonstrating that knowledge, and particularly the integration of knowledgeacross firm boundaries, is a central property of product development. The study focuses on industrial andmanufacturing firms, complementing current perspectives on the role of customers in other sectors. In thisparticular sector, complexity and system-wide implications need to be resolved together with customers throughknowledge integration activities. An important implication of the thesis is that firms need to devise mechanismsfor knowledge integration with customers, and be prepared to redevise these as the firm progresses through theproduct development phases.

    Efficient collaboration between main and sub-suppliers2002In: Computers in industry (Print), ISSN 0166-3615, E-ISSN 1872-6194, Vol. 49, no 1, p. 25-35Article in journal (Refereed)
    Abstract [en]

    Many sub-suppliers are interested in closer integration with main suppliers for product development. However, main suppliers have much work that needs to be coordinated, and close integration with suppliers is used only when it is required, and when additional value is created through integration. The main objective of this paper, is therefore, to discuss different supplier roles and increase the understanding of how suppliers can be integrated with the main supplier. The result is based on a case study with one main supplier and nine of its sub-suppliers, where the main supplier develops, assembles, and delivers a complete, complex product to the customer, and the sub-suppliers develop and manufacture sub-systems for the main supplier. The results give new insights into what the sub-suppliers could do in order to improve integration with the main supplier.

    Designing proactive assembly systems: Criteria and interaction between automation, information, and competence2010In: Asian International Journal of Science and Technology in production and manufacturing engineering (AIJSTPME), ISSN 1906-151X, Vol. 2, no 4Article in journal (Refereed)
    Abstract [en]

    Production companies of today face extreme challenge to meet the rapid changes and increased flexibility that mass customization require. More and more customers are requiring the product to suite specific needs such as design, function and sustainability. These requirements results in increasing demands for the developers of the product but also for the personnel who will assemble the products in the final assembling. This paper suggests the need for further development, primarily addressing time parameters in dynamically changing assembly systems. We propose proactivity as a vital characteristic of semi-automated assembly systems, to increase fulfilment of customer demands and decrease non value-adding tasks. In proactive assembly systems, the potential of human operators and technical systems is utilised. Criteria for proactivity are reviewed from automation, information, and competence perspectives. Empirical data have been collected from five production companies in Sweden.

    Abstract [en]

    In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.

    The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.

    The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data. Many questions have also been clarified through additional interviews and some meetings. This has made it possible to analyze the total production time of most work stations. Studies of Mathematical Statistics show that the total time variance is made up of the different work stations variance. This insight has influenced us in our analysis of the various work stations.

    After the analysis and discussion between us and the company's technical director together with production engineers concerning the time parameters for each workstation a pilot template and user guide were designed. The pilot template and user guide has been developed in accordance with the theory of visualization and has been evaluated by the company's production and marketing departments. This generated a final proposal on the spreadsheet template and user guide. This proposal is an Excel-based spreadsheet template consisting of six tabs: Presentation marknad, Presentation teknik, Variabler, Konstanter, Formler and a user's guide which highlights the use of the tabs. "Presentation marknad” shows what marketers need for their work and the "Variabler" for the engineers. Tabs and User Manual has been designed with visualization in mind, for example, have different font sizes and colored text been used. Tabs "Konstanter" and "Formler" is the basic data and information on how core data can be changed when the need arises. The reason for the last two tabs characteristics is that through our identification and analysis of workstations and own studies performed by the company, the company is allowed to increase the templates accuracy compared to reality.

    Kostnadskalkylering på en förpackningsavdelning2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This degree project is based on identifying and allocation of costs in a packaging section at Electrolux Distriparts in Torsvik.

    The purpose of this thesis is to identify the costs that emerge when packaging different articles and show how the costs are allocated. The report also contains improvement suggestions about how the company can use the current computer system more efficient.

    The methods that have been used in order to approach the problem and the collection of information have mainly been literature study, interviews and observation.

    The work started with answering the questions; which expenditure cost and direct cost exist in the section, how can they be allocated, if improvement can be done and how the flow of information is supposed to happen.

    In order to answer the questions we used our former experience and the knowledge we achieved by reading literature, interview relevant persons in the company and observations carried out in the section.

    Through our studies, we came up with an Excel file, which is the groundwork for a template that can be used by the company in different occasions depending on the situation and need. It is important to remember to modify the template if the presumptions change. In the template, we have identified the different kind of costs that emerge when packaging different articles and we have also allocated the costs. In addition formulas and estimations that are necessary for the cost calculation are presented.

    The work consisted in making the groundwork for a template. That means there is a lot of work for the company left to do until the template is ready to be used in working routine.

    The template includes estimations that are not tested with real figures and therefore can contain hidden defects. The company could not supply us with the figures on the relevant costs, because of secrecy reason. Therefore it is very difficult to eliminate the risk for hidden defects in the template. In order to distinguish obvious defects, made up figures were used. These can differ essential from the real figures, but the purpose is to minimise the defects and help the company to see how the template works.

    An improvement suggestion is that the company should use the proposed flow of information in order to save time and therefore be able to spend more time with the main operations. The flow of information saves time by:

    • Using more the current computer system

    • Being simple

    • Identifying unnecessary activities, so that it can be removed or modified

    Information enabling production ramp-up2009In: Journal of Manufacturing Technology Management, ISSN 1741-038X, E-ISSN 1758-7786, Vol. 20, no 2, p. 178-196Article in journal (Refereed)
    Abstract [en]

    Purpose – This paper seeks to identify information enabling and supporting production ramp-up processes, by exploring critical events and the role of information in such events.

    Design/methodology/approach – The research approach was based on empirical and theoretical investigations. A selection of 30 events, considered the most critical for production ramp-up realization and/or performance at one Swedish automotive company, were categorized and constituted the base for the analysis which focused information types and sources enabling event handling.

    Findings – Information enabling event handling is a balanced combination of problem and domain information, regardless of event category. However, a differentiation concerning preference and usage of information types between experienced and less experienced personnel is identified. Problem-solving information has the character of pragmatic information, composed of complementary parts of confirmation and novelty in terms of domain and problem information. The preferred information source in all event categories was “other people”.

    Research limitations/implications – The study focuses on the application of information in relation to critical events during production ramp-up. General information theory is not addressed in depth.

    Practical implications – Information type and information source are not dependent on certain event categories, which allows a general information strategy enabling production ramp-up. To facilitate production ramp-up and event handling managers and key personnel need to apply a holistic perspective and need to be updated on domain information of the products, the equipment, and the production process during production ramp-up.

    Originality/value – The originality is in the focus and role of information to achieve an efficient production ramp-up performance. A supporting model is developed which describes the structure of pragmatic information for personnel with various levels of experience, regardless of event category.
