    A case study of how knowledge based engineering tools support experience re-use2011Ingår i: Research into Design: Supporting Sustainable Product Development / [ed] Amaresh Chakrabarti, Bangalore, India: Research Publishing Services, 2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    A manufacturing company’s unique intellectual capital is to a largeextent built on experience from its own product development andmanufacturing processes. Thus, methods and tools to utilize and benefit fromthis experience in an efficient way have an impact on a company’s ability tostay competitive and advance on the global market. Knowledge BasedEngineering (KBE) is an engineering methodology to capture engineeringknowledge systematically into the design system. Hence, KBE tools areconsidered to support experience re-use and improve engineering activities.This paper presents the results from a study where the objective was toinvestigate the support for experience re-use in KBE applications in anaerospace company. A proposed framework is presented to analyze thecapturing and use of experience in a company’s processes identifying gaps andpropose improvements. The study revealed weaknesses in the process steps forexperience feedback which can be used to improve KBE applications further.

    Project: Robust Machining2010Övrigt (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    New generations of environmentally friendly and safe vehicles require manufacturing of light weight materials with higher strength and, as a consequence, tougher machining conditions and increased machining robustness. There is a lack of practical and reliable methods and tools to meet these challenges in the automotive industry. The very complex system of machine tool, fixture, cutting tools and the machined part is almost impossible to model without complementary measurements of the real system at the factory floor in full production. Using Virtual Engineering together with studies of machining processes the project team will assess these challenges.

    Abstract [en]

    This study is based on data from a Swedish real-life industrial product development project for e-health care of elderly. The purpose in the paper is to discuss identification of user needs. Information about the elderly is transferred in recurrent meetings. Besides the perception that these meetings occupy time which could be spent giving care, the nurses find it problematic to convey such information to substitutes, as well as they have to rely on their memory. In this case, a Dictaphone device was a solution. Reports on practical activities of identifying user needs and how they affect decisions in product development are limited; one contribution of this paper is insights into such a case

    Assessing the value of sub-system technologies including life cycle alternatives2011Ingår i: Glocalized Solutions for Sustainability in Manufacturing: Proceedings of the 18th CIRP International Conference on Life Cycle Engineering, 2011, s. 669-674Konferensbidrag (Refereegranskat)
    Abstract [en]

    Emerging from an industrial case study in the aerospace industry, the paper proposes an approach to evaluate subsystem technology concepts from a life cycle perspective. The approach is composed by 5 main phases that aims to drive product designers towards more value-oriented design decisions. It is shown how different life cycle alternatives, such as the selling of a Product-Service- System instead of a traditional product, deeply impact the value of design alternatives. The described approach has been developed in collaboration with industrial partners and represents a potential instrument to enhance value-driven product design.

    Pilot specifications definition guidelines for the implementation of a KEE solution in the aeronautical domain2008Ingår i: CIRP Design Conference 2008: April 7 - 9, 2008, Enschede / [ed] Fred J. A. M. van Houten, Enschede: Laboratory of Design, Production and Management, Faculty of Engineering Technology, Univ. of Twente , 2008Konferensbidrag (Refereegranskat)
    Abstract [en]

    The design and implementation of a new Knowledge Enabled Engineering (KEE) in the context of a Virtual Enterprise is a labour intensive and risky task. In order to check, before embarking on a full-scale implementation, if the system will satisfy initial expectations, physical prototypes (Pilots) have to be tested in a near real usage environment to obtain qualitative and quantitative information for the final tuning activity. This paper proposes a methodology to guide this Pilot specifications definition process. The main aim of the roadmap proposed is to support the KMS design team in configuring a Pilot solution able to provide valid feedbacks of final system behaviour both from a software and non-software point of view.On one side the methodology guides the definition of Pilot implementation specifications from a technical perspective. It helps engineers and knowledge experts in selecting, refining, merging and cascading down the initial heterogeneous Pilot high level objectives to a lower level, and in elaborating a functional description of the KMS prototype. It proposes, moreover, a structured framework to classify KMS' performance indicators to help the Pilot task force in properly carry out the validation task.The methodology, on the other side, pushes the design team in considering those behavioural and methodological issues that arise from the necessary change in work practice as a result of implementing the KMS within a Virtual design environment. In parallel with the definition of technical specifications, the roadmap supports knowledge experts in developing and testing a set of Knowledge Management guidelines, intended as a list of Best Practices and Lesson Learned aiming to help users in utilizing the potentialities of the new solution.The methodology has been developed within the European project VIVACE to support the design and implementation of a new KEE system in the aeronautical domain.

    Needs and requirements: how TRIZ may be applied in product-service development2009Ingår i: Proceedings of the 2nd Nordic Conference on Product Lifecycle Management - NordPLM'09 / [ed] Johan Malmqvist; Göran Gustafsson, Göteborg: Chalmers tekniska högskola. Institutionen för produkt- och produktionsutveckling , 2009Konferensbidrag (Refereegranskat)
    Abstract [en]

    In Product-Service Systems development, understanding of the customers' use of goods seems vital, since the product per se is not sold but rather the performance it brings to the customers' processes in terms of added value. This changed business scenario insists on an integration of a service and a product perspectives in early design phases. However, the approaches to understand customers diverge. In this paper, a need matrix, from the economic theory of needs, and a requirement matrix, from the TRIZ methodology, are used to elaborate on integration aspects to understand customer statements. The comparison of these matrixes made the distinct logics apparent, and gave an indication for the necessity of another type of specification for PSS products. Also, the knowledge base for PSS methodologies has to be extended to encompass a part that visualizes non measurable aspects such as needs.

    Methods and tools for knowledge sharing in product development2011Ingår i: Innovation in Product Design: from CAD to virtual prototyping, London: Encyclopedia of Global Archaeology/Springer Verlag, 2011, s. 37-53Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    The emerging industrial business partnerships, which feature cross-functional and cross-company development efforts, raise the barrier for the establishment of effective knowledge sharing practices in the larger organization. This chapter aims to highlight the role of knowledge as a key enabler for effective engineering activities in the light of such emerging enterprise collaboration models. Knowledge Enabled Engineering (KEE) is presented as an approach to enhance the extended organization’s capability to establish effective collaboration among its parts, in spite of different organizational structures, technologies or processes. KEE is analysed in its constituent parts, highlighting areas, methods and tools that are particularly interesting for leveraging companies’ knowledge sharing capabilities.

    The rise of social product development2012Ingår i: International Journal of Networking and Virtual Organisations, ISSN 1470-9503, E-ISSN 1741-5225, Vol. 11, nr 2, s. 188-207Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of the paper is to discuss the rising potential of social software to increase the knowledge management capabilities of virtual product development teams. It presents six fundamental transitions, elaborated from the empirical findings, which justify the rise of a more bottom-up, social creation and sharing of engineering knowledge in the virtual organisation. The study suggests that traditional engineering knowledge management approaches alone are not sufficient to support development activities in the virtual organisation, and that such teams display an increasing demand for social, comparatively lightweight and remixable platforms for bottom-up, social creation and sharing of knowledge.

    Requirements for a KEE system supporting PSS development2009Ingår i: Research into design: supporting multiple facets of product development / [ed] Amaresh Chakrabarti, Singapore: Research Publishing Services, 2009Konferensbidrag (Refereegranskat)
    Abstract [en]

    In Product Service Systems development, understanding the customer use of goods is vital, since the product per se is not sold but rather the performance it brings to the purchaser in terms of added value. Moving away from offering just a product or service to become a provider of "integrated solutions" implies inevitable changes in the interaction with the customer as well as in the way knowledge is managed and shared in the cross company environment. The main aim of this paper is, on one hand, to provide examples of how Product-Service Systems raise the demand on such cross-functional knowledge sharing; on the other hand it aims to point out a set of requirements for the successful development of Knowledge Enabled Engineering systems able to support a PSS paradigm in a Virtual Enterprise context.

    Multidisciplinary design tool for conceptual design and evaluation2005Ingår i: 15th International Conference on Engineering Design - ICED 05: 15 - 28 August 2005 / [ed] Andrew Samuel; William Lewis, Barton: Institution of Engineers, Australia , 2005Konferensbidrag (Refereegranskat)
    Abstract [en]

    The actual product ownership often remains with the manufacturer as functional (total care) products emerge in aerospace business agreements. The business risk is then transferred to the manufacturer why downstream knowledge needs to be available in the concept phase to consider all product life cycle aspects. The aim of this work is to study how a multidisciplinary design tool can be used to embed downstream processes for conceptual design and evaluation allowing simulation of life cycle properties. A knowledge enabled engineering approach was used to capture the engineering activities for design and evaluation of jet engine component flanges. For every design change, cost of manufacturing operations, maintenance and performance aspects can be directly assessed. The design tool assures that the engineering activities are performed accordingly to company design specification which creates a better control over the process quality. It also creates a better understanding enabling the engineers to optimize the concept in real time from an overall product life cycle view. The new tool will be the base for optimize the total product system and will be used not only between companies but also between product development departments in large global companies.

    Abstract [en]

    The objective of this paper is to discuss how Knowledge Enabled Engineering, when combined with simulation methods is a development step for product development processes, engineering design methods and evaluation support systems. The paper opens the discussion on how these approaches, i.e. work methods, simulation support and Knowledge Enabled Engineering (KEE) methods affects best practice in engineering design (ED) by adding synthesis support to the already existing analysis support. In the presented work the authors discuss the actual state of industrial applications, with challenges and opportunities, at Volvo Car Corporation, automotive manufacturer, and Volvo Aero Corporation, jet engine component manufacturer, both operating in Sweden.

    Knowledge sharing across boundaries: Web 2.0 and product-service system development2011Ingår i: Research into Design: Supporting Sustainable Product Development / [ed] Amaresh Chakrabarti, Bangalore, India: Research Publishing Services, 2011Konferensbidrag (Refereegranskat)
    Abstract [sv]

    Under senare år har det funnits ett växande intresse bland organisationer som arbetar med produktutveckling att utnyttja sin tekniska kunskap som huvudsaklig konkurrensfördel för innovation. Fånga, lagra, hämta, dela och återanvändning av kunskap från en rad olika affärssystem har blivit avgörande aktiviteter när det gäller kunskapshantering. Mot bakgrund av en föränderlig och dynamiskt företag miljö, samt en övergång till Product-Service System (PSS) utveckling, diskuterar denna artikel några av begränsningarna för dagens affärssystem beträffande återanvändning av ingenjörskunnande över funktionella samt företagens gränser. Vidare visar artikeln på hur Web 2.0-baserade samarbetsprojekt kan utnyttja tvärfunktionellkunskap för nya PSS utvecklingsprojekt, genom ett öppet, “bottom-up”, och kollektivt “sense-making” förhållningssätt till kunskapshantering.

    The nonlinear behaviour of a pantograph current collector suspension1999Ingår i: Proceedings of the 1999 ASME Design Engineering Technical Conferences, 1999Konferensbidrag (Refereegranskat)
    Abstract [en]

    The pantograph-catenary system is a critical component for trains required to run at higher speeds. The pantograph often includes nonlinear characteristics and the scope of this work is to investigate if nonlinear dynamic phenomena can occur in an existing design. A model of a pantograph suspension subsystem has been developed according to physical parameter values of the head suspension of the Schunk WBL88/X2 pantograph, providing electric power to the Swedish high-speed train X2. Studies of the system response for different force excitation show both harmonic, subharmonic and chaotic behaviour for the investigated parameter regions.

    Modelling and simulation of catenary-pantograph interaction2000Ingår i: Vehicle System Dynamics, ISSN 0042-3114, E-ISSN 1744-5159, Vol. 33, nr suppl, s. 490-501Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Modelling and simulation of the dynamic behaviour of catenary-pantograph interaction is an important part when assessing the capability of a current collection system for railway traffic. The large variation in infrastructure characteristics in different countries and railway companies, different types of traffic, designs of pantographs etc. makes it almost impossible to develop a final simulation model of such a system. Instead, it would be favourable to have a tool that has the ability to set up models of such systems, choose relevant detail of the models, run simulations and finally visualize the results. To make the tool useful for engineers, design experts as well as simulation experts, the functionality of the tool must be worked out. Aspects on computer simulation such as developed models, simulation methods and computer tools are presented. The aim is to develop a scenario that considers different designs, models, solution methods and user levels. The scenario focuses on how to structure the use of simulation of dynamics in catenary-pantograph development. A scenario is sketched built on different user levels, a modular structure and a structure for information management

    Abstract [en]

    This work is part of a study where a descriptive and a prescriptive approach have been used. This paper deals with the descriptive part and discusses views on decision support in product development to identify factors of relevance to con-sider when designing computer-based decision support for total offers. Providing services in form of physical artefacts offered as ‘functions per unit’ is at the heart of total offers. The intention is to provide customers with functions in time and place ‘as-needed’, based on a life-cycle commitment. This new scenario is found in manufacturing industry in addition to a traditional view on selling hardware and providing aftermarket activities. Total offers gain access to possibilities to ‘design in’ value added characteristics into the physical artefact, e.g., maintenance, moni-toring, training and abilities to upgrade and/or remanufacture. Computer tools is commonly used to supply design teams with information which is relevant, correct and in time to support resolutions, yet to support a GO/NO GO decision for total offers contemporary tools seems to be insufficient. Relevant factors to take into consideration are to support learning and provide the decision makers with insights in a number of plausible ‘what-if’ scenarios to im-prove the solution space.

    A service perspective on product development: towards functional products2005Ingår i: Proceedings of 12th International Product Development Conference: IPDM, 2005Konferensbidrag (Refereegranskat)
    Abstract [en]

    Functional products are understood as a combination of hardware, software and services. Based on interviews with employees in manufacturing firms the notion of functional product development is described. The purpose has been to explore the differences between a service perspective and a core product perspective and highlight changes in the management of product development processes that are motivated by the notion of functional products. Exploring the differences between the two perspectives has identified a gap of how the product is viewed at the business level and technical development levels. The integration of services into the hardware development process in the form of a customised product or product life cycle has been highlighted. Internal and external communication about needs has been identified as useful.

    Abstract [en]

    The adaptation of Product/Service-System calls for new development models. On one side this businesses give the manufacturing firm possibilities to redesign, upgrade and replace the discrete device that provides the performance their customers are asking for. On the other side, this new situation has to address aspects that are normally not addressed in early product development, i.e., services. In this chapter, we will elaborate on product and service development processes models, as well as system models to propose a frame of reference for multiple perspectives on PSS development. These perspectives are people, product and process. Also, this chapter puts forward implications for the development of PSS models.

    Abstract [en]

    Product-Service Systems (PSS) has now for more than a decade been a research interest in Europe and Japan. The research aims to support manufacturing industries’ ability to provide value in terms of a service offer to its customers, simultaneously taking a more holistic approach to eco-sustainability. The idea of providing customer benefits in parallel with robust products is not new, yet equipping engineers to integrate a radical innovation and service perspective in the early design stages is received as fairly radical. Prevailing methods, tools and design thinking are barriers that prevents approaching PSS by the necessary integration of several, but distinct, logics.Due to the inclusion of both product development and service development in development of PSS, at least, two schools of thoughts exist within the research field of PSS development. Namely, one based on product development rationality and one based on service provision reasoning. In general, such a situation would be a base for a conflict where the debate focuses, which strand that should be more valid than the other. However, if so, this would certainly not benefit the need for cross-disciplinarily research of PSS. The purpose in this paper is two-fold; first, to describe PSS research efforts by acknowledging both the product and the service perspective, second to explore and discuss future directions and by that identify “white spots” on the map which may be seen as relevant to bridge the integration gap.

    Abstract [en]

    The extension of businesses to incorporate the provision of function as a service in supplement to standalone products is an ongoing movement in manufacturing industry. In short, this means that the development intent should be guided by the need of ‘performance in use’ that the customer wants, e.g. thrust rather than an engine. By this, the established knowledge base challenges the development team.This paper embarks from the assumption that there are three main challenges, i.e. (1) innovation activities, (2) customer data acquisition and (3) the transformation of data into design information. The purpose is to discuss knowledge sharing activities to contribute to product-service innovation. In this study it has been found that contemporary data acquisition activities filter out important dimensions of knowledge. Thus, does not provide a sound base for service provisions.

    Abstract [en]

    “Listen closely to your customers, and you are more likely to design products that actually meet or even exceed their needs.”: Such statements have come to dominate company innovation strategies in the last decade, but in reality involving customers in product development is not as straightforward as it sounds. Customers, it is becoming clear, cannot always express their needs adequately. Especially, in the case of innovative products where the starting position by definition includes no existing solution, applying a user-orientated approach is paramount. We argue that techniques for ‘needfinding’ must be the point of departure. This has importance both in terms of methodological issues – how to find customer needs? – and for organizational work – who should be engaged in finding customer needs? In our view, engineers must be involved in identifying and understanding those needs. We have learnt through a series of studies, that structured needfinding by engineers during the earliest phases of product development could better support the process of identifying needs and thereby guide design projects. In this way, two basic problems are overcome. Firstly, identifying needs which are otherwise difficult to articulate becomes possible. Secondly, translation difficulties between customers and engineers are eradicated

    Need driven product development in team-based projects2007Ingår i: Design for society: knowledge, innovation and sustainability ; ICED '07 - Paris, 16th International Conference on Engineering Design ; 28 - 30 August 2007, Paris, France ; conference proceedings, Paris, 2007Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper, practical activities of needfinding - an intertwined approach to identifying needs and to visualizing idea concepts in early design - are described and discussed. This is done primarily to gain an increased understanding of the various representations of user needs that are fed into the fuzzy front-end activities of team-based product innovation projects. The empirical basis comes from a study of an eight-month collaborative product development project, performed under realistic conditions by MSc students in close collaboration with their client.Focusing closely on customers and their needs is encouraged within the conceptual framework of Integrated Product Development and is increasingly highlighted as a key enabler in the design of truly innovative products. Despite the fact that identified customer needs are considered as the initial and primary input into such an innovation process, it can be argued that the design teams do not commonly have a sufficient understanding of customer needs and they do not normally interact with customers in their environment. Besides focusing on measurable aspects of user behaviour and requirements, a traditional approach to identifying and managing customer needs usually includes several interpretive stages before being handed over to the design team. In the context of innovative products, the identification and definition of customers and their needs is a non-trivial and difficult exercise. It involves, we suggest, not only needfinding but also the definition of ‘those who might need the product’, users and customers to co-evolve iteratively in the early phases of design.

    Functional product innovation: reaping the benefits of simulation driven design2007Ingår i: Knowledge Sharing and Collaborative Engineering: Proceedings of Fourth IASTED International Conference on Knowledge Sharing and Collaborative Engineering, KSCE 2006 / [ed] M.

    Abstract [en]

    Despite a tradition in selling and developing physical artefacts while viewing services as add-ons, the view on products in Swedish industry extends to include total offers, i.e., service provision. The service providing companies take extended long-term responsibilities regarding the physical artefact and the agreed upon functions. The changed business scenario affects product development, in particular the early phases. A life-cycle perspective, cross-company collaboration and customer needs are issues to take into consideration early on in product development. An extended enterprise business model is presented in this paper to give a notion of the changed input for product development. This is done for the purpose of discussing a simulation driven design approach in relation to a vision for functional product innovation. In an engineering design environment, computational support is commonly used to provide a basis for decisions in product development. In this paper we suggest a new, and additional, way to think about design and to use simulations. We suggest that simulations should be used to drive, and not only verify, the design of a product, and thereby also nurture innovations.

    Knowledge exchange challenges within the extended enterprise2005Ingår i: 15th International Conference on Engineering Design - ICED 05: 15 - 28 August 2005 / [ed] Andrew Samuel; William Lewis, barton: Institution of Engineers, Australia , 2005Konferensbidrag (Refereegranskat)
    Abstract [en]

    The notion of functional products changes the existing relationship between manufacturing companies. The integration of hardware, software and services in functional products calls for close collaboration with companies having complementary skills. When employees from different companies are involved, strategic resources such as knowledge are shared. From an engineering design perspective, knowledge sharing supported by software systems are useful, though it seems like functional product development insists on integrating multifunctional skills and this is likely to affect the design of software systems. The objective in this paper is to explore knowledge sharing challenges between manufacturing companies, striving to create close functional product collaboration, and hence understand aspects in the design of software systems. In this paper the focus is on Knowledge Based Engineering (KBE) systems, these are considered to be internal engineering specific tools, while collaboration and need for knowledge sharing calls for coupled KBE systems between partners. In this context, knowledge sharing challenges within the extended enterprise are recognised to issues about who to trust and what and how to share. This affects how tightly coupled KBE systems can be. In general, this paper contributes to the ongoing discussion concerning collaboration issues in concurrent engineering design, but especially to the overall understanding of what new demands on KBE systems that are motivated by functional product collaboration.

    Abstract [en]

    A major challenge for the automotive industry is to reduce the development time while meeting quality assessments for their products. This calls for new design methodologies and tools that scale with the increasing amount and complexity of embedded systems in today's vehicles.In this paper we undertake an approach to embedded software design based on executable models expressed in the high-level modelling paradigm of Timber. In this paper we extend previous work on Timber with a multi-paradigm design environment, aiming to bridge the gap between engineering disciplines by multi-body co-simulation of vehicle dynamics, embedded electronics, and embedded executable models. Its feasibility is demonstrated on a case study of a typical automotive application (traction control), and its potential advantages are discussed, as highlighted below:shorter time to market through concurrent, co-operative distributed engineering, andreduced cost through adequate system design and dimensioning, andimproved efficiency of the design process through migration and reuse of executable software components, andreduced need for hardware testing, by specification verification on the executable model early in the design process, andimproved quality, by opening up for formal methods for verification.

    Abstract [en]

    The ongoing transition challenges the way we work since ownership and responsibility for the product we use changes. Increasingly, manufacturers become service providers rather than product providers.So far – the focus on this transition has been on the service dimension itself – and comparatively little has been suggested on how the products themselves are affected when integrating the service and product dimensions.A framework is suggested where the life cycle of a Product/Service System is presented. The framework is represented by five life cycle phases where three actor categories views are represented. The framework is described using examples from different industries/businesses.The intention is that the framework can be used for both B2C and B2B type of relations. One core characteristic is that the “traditional” sales phase is replaced by a sales occasion that occur within different life cycle phases depending on which business context/model is used.

    Abstract [en]

    Total Offers, Functional Products, and Integrated Product Service Engineering reflect a shift toward service offers from manufacturing industry captured within the term Product-Service Systems (PSS). Manufacturing companies have traditionally focused design and development activities on realizing technical and engineered aspects of physical artifacts, while PSS include deeper understanding of customers’ expectation, needs and perceived value, hence calling for modelling of additional aspects. The change in early design processes and the effects on virtual modelling of product properties are discussed in this paper through aerospace industry examples to clarify ‘parameters of change’, giving suggestions for a simulation driven design (SDD) approach.

    Abstract [en]

    VIVACE is an EC-funded integrated project that addresses aeronautics´ vision for the year 2020. More specifically VIVACE intends to achieve cost reduction and time reduction in new aircraft development. VIVACE consists of three sub-projects where the two first extracts problems from aircraft and engine industries respectively. The third sub-project collects these problems and develops advanced capabilities (methods, tools, guidelines, etc.). The ’Knowledge Enabled Engineering’ (KEE) work package in sub-project three focuses issues on concerns associated with knowledge within an extended enterprise. This includes both Knowledge Based Engineering (KBE) issues, but also more general questions about engineering knowledge. The work starts in analysing requirements from use cases via finding existing solutions to conducting tests in the form of pilots. Finally the knowledge acquired is disseminated to both the aeronautics community and also to a wider audience in Europe and the rest of the world.

    Gated maturity assessment: supporting gate review decision documents with maturity of knowledge assessment2008Ingår i: CIRP Design Conference 2008: April 7 - 9, 2008, Enschede / [ed] Fred J. A.

    Abstract [en]

    In aeronautics industry today, companies collaborate closely in virtual enterprises to develop products and solutions that are more integrated and more complex, and that aims to target larger responsibilities regarding the product life-cycle. On top of this, lead-time and development costs needs to be reduced.The 7 Day Proposal (7DP) is the conceptual name of a framework wherein a customized proposal is produced by a virtual enterprise consortium within seven days from a received request for proposal. This is substantially shorter than what is current practice today and implies that new methods, tools and ways of working are needed. Today, in offer processes, time is lost because of insufficient, or immature, available information and knowledge at gate reviews when decisions are due, causing time consuming iterations. The Gated Maturity Assessment (GMA) concept is intended to help reduce these costly iterations by targeting the ambiguity at these gate reviews in order to reduce the uncertainty in decision base. Other frameworks using maturity include Technology Readiness Levels (TRL) and the Capability Maturity Model (CMM). TRL is an artefact-focused framework developed by NASA to assess space technology maturity. CMM is a process-focused framework for assessing organisations' software development process capability (maturity). The GMA is a concept for assessing the maturity of the knowledge that goes into a gate review (i.e. a decision document). The GMA is intended to support decision makers by assuring confidence in these decision points and thereby reducing the number of iterations, hereby reducing lead-time and increases the quality of the process.This paper reports on the development of the GMA concept from the 7DP use case, and also the development of a support tool intended for use in the 7DP process. Essentially, the 7DP process is a stage-gate process like many corporate product development processes with a number of decision gates. Therefore there is a future wish to move towards an engineering design context with this concept. The work is part of the 70 million € European project VIVACE where GMA is part of a Knowledge Enabled Engineering solution to the 7DP use case.

    Abstract [en]

    This paper consists of a case study of the product development process at Indexator AB, manufacturer of rotators for heavy equipment. The process has been studied concerning the information flow and computer support in the engineering design department and its interacting departments. It is shown that the company has a clear view of how information flows and which computer tools they use in the different parts of the processes. The advantage of using computer tools for analysis and planning is seen. Ways of communication and information flows concerning the design processes can sometimes happen in unplanned ways. Lack of integration between the different computer tools leads to unnecessary regeneration of the product information in the different parts of the development process.

    Lightweight technology support for product/service systems development2010Ingår i: Industrial product-service systems (IPS²): proceedings of the 2nd CIRP IPS² Conference [2010, Linköping, 14-15 April] / [ed] Tomohiko Sakao, Linköping: Linköping University Electronic Press, 2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    Product/Service-Systems (PSS) strategies can be observed as part of an overall movement towards a service-based society that is increasingly knowledge and information based, and where sustainability is in focus. PSS deals are contracted on the characteristic to provide ‘functions per unit’. The ownership of the physical product may remains with the manufacturer or a joint venture, a venture that will operate in a cross-company situation with a multitude of knowledge workers.Knowledge sharing for cross-company innovation projects has been recognised as troublesome, since disparate knowledge domains must be brought together in a cohesive way to support creativity and also innovations. This paper describes an approach to lightweight knowledge sharing for the purpose of supporting cross-functional design. This ‘Engineering 2.0’ approach makes it possible to link, with low overhead effort, customer needs, support issues etc directly to the development teams responsible for developing solutions to the identified issues.

    Abstract [en]

    In a traditional business partnership, the partner companies are under contractual obligation to share data, information, and knowledge through one or several information systems that the leading firm decides. In such a case, the issue of sharing "whatever needs to be shared" is settled in contracts before any action is taken, however, also giving the implications that sharing expertise becomes a heavy and time-consuming activity. In turn, it can be argued that the heavy administration affects the lead time of product development negatively since the necessary input flows are delayed. In addition, the adaptation to certain predefined collaborative information systems is both expensive and resource-consuming (e.g., educating staff to use them). Also, the system might not be adaptable to the existing internal technology structure, causing a "translation" procedure, again taking up resources. Another structure for collaboration is a network or alliance of independent partner companies. One motivation for a network structure is that the partners can join or leave it more easily. A reason for joining and staying is an implicit sense of knowledge sharing (Tomkins 2001) and access to a "win-win" environment. Furthermore, the partners can be linked by information technology, i.e., forming a virtual ­structure rather than a physical one. The technologies provide the channels with additional knowledge. In a best-case scenario, a company would get access to a wide range of useful competences, and in a worst-case scenario the company would be drained of its core competences. Accordingly, at least two considerations for joining a partner network can be considered. First, the resources needed to couple the technologies have to be reasonable, due to the underpinning logic of going in and out of more than one network. Second, the company has to identify its knowledge base and evaluate the prospective gains and losses of sharing its expertise.

    Abstract [en]

    In a Virtual Enterprise setting, it becomes increasingly important to make sure that knowledge and expertise created in one discipline, domain or company is correctly understood and quickly utilized by other actors throughout the value chain. This paper discusses why lightweight technology seems like a particularly promising concept in this context, and why Virtual Enterprises could benefit from learning more about tag clouds, mashups, wikis, and other ‘lightweight' technologies, as complements to the large-scale, arguably ‘heavyweight', product life-cycle management (PLM) systems of current practice. The paper draws on data from a number of product development projects - ranging from the development of manufacturing tools and industrial drive systems, to aircraft engines and armored terrain vehicles. The paper identifies both the kinds of problem typically experienced in the Virtual Enterprise, in relation to knowledge sharing, and explores ways in which lightweight technology might be adapted to solve them.

    Abstract [en]

    The IMG4 project CRESCENDO addresses the Vision 2020 objectives for the aeronautical industry by contributing significantly to the fulfilment of three specific targets of the aeronautical industry’s Strategic Research Agenda. CRESCENDO will develop the foundations for the Behavioural Digital Aircraft (BDA),taking experience and results from VIVACE, and integrating these into a federative system and building the BDA on top of them. Main components of the BDA are: the Model Store, the Simulation Factory, the Quality Laboratory, and the Enterprise Collaboration Capabilities. It will be validated through use cases and test cases concerning “Power Plant Integration”, “Energy Aircraft”, “Thermal Aircraft” and “Value Generation” design problems and viewpoints during the preliminary design, detailed design, and test and certification phases of a generic aircraft product life-cycle. The BDA will become the new backbone for the simulation world, just as the Digital Mock-up (DMU) is today for the Product Life-cycle Management (PLM) world. This is considered a challenging area for research and innovation for the next decade. Hence, the CRESCENDO results will provide the aeronautics supply chain with the means to realistically manage and mature the virtual product in the extended/virtual enterprise with all of the requested functionality and components in each phase of the product engineering life cycle. CRESCENDO will make its approach available to the aeronautics supply chain via existing networks, information dissemination, training and technology transfer actions. The project will last three years and be organised into six subprojects: four technical and business-oriented subprojects, one “Enabling Capabilities” subproject which will deliver the BDA and a sixth subproject, responsible for consortium management and innovation issues. CRESCENDO will bring together 59 partners from industry, research institutes, universities and technology providers

    Abstract [en]

    There is a growing need for engineering designers to engage in creative activities that result in innovative products and technologies for the benefit of society. However, from an engineering perspective, issues of ‘life quality’ are currently heavily under-prioritized, particularly with regard to people with disabilities. This paper argues that both needs and solutions are now part of the designer’s responsibility, and that it is crucial to make a qualitative assessment of both the potential market impact and the ‘quality of life’ improvements afforded by innovations. Design for Wellbeing offers a perspective on life quality that goes beyond the traditional scope of assistive technology in that it aims to help people make a transformation from an actual state of being to a desired state of being – regardless of ability level.

    Intranet - Luleå University of Technology2001Övrigt (Övrigt vetenskapligt)
    Abstract [en]

    The Division of Computer Aided Design has been announced as one of ten winners in the Intranet Design Annual, published by web guru Jakob Nielsen at Nielsen/Norman Group. In competition with over 50 nominated organizations, the division's Intranet, developed by Andreas Larsson, Tobias Larsson and Peter Törlind, reached the top ten. Nielsen has been called the "guru of webpage usability" by the New York Times, and he currently holds 60 U.S. Patents, most of them concerning web usability. The report states: “It is also notable that Luleå University of Technology made it to the top 10, despite being designed by a bunch of graduate students. Though small and lacking a lot of resources, this design team focused relentlessly on user needs and on simplifying their design through many fast iterations. Some of the Luleå features underwent up to 50 iterations before they reached their current usability level. ‘I thought my initial design for the calendar application was really easy to use - in fact, I was quite proud of it,’ says one of the developers. But, the design didn’t hold up when professors and other staff members used it, so it was changed. User needs triumphed over the designer’s initial pride. That’s the hallmark of a truly great designer. On a small budget, the way to achieve high-quality design is through fast, cheap iterations and a willingness to do what users need.” http://www.useit.com/alertbox/intranet_design_2001.html http://www.nngroup.com/reports/intranet/2001/

    The Mobile intranet: managing people and information in a distributed organization2002Ingår i: WWDU 2002: Work with display units - world wide work : proceedings of the 6th International Scientific Conference on Work with Display Units, WWDU 2002 - World Wide Work, Berchtesgaden, May 22 - 25, 2002 / [ed] Holger Luczak, Berlin: Ergonomic, Inst. für Arbeits- und Sozialforschung , 2002Konferensbidrag (Refereegranskat)
    Abstract [en]

    As a result of the increasing globalisation of organizations, information systems must deal with issues of mobility. Longer distances between the members can lead to a knowledge gap, which means that two groups of people working in the same organization work according to completely different bases of information. Thus, there is a need for the members of an organization to communicate efficiently across geographical and departmental boundaries. The paper discusses motives, methods and experiences from the participatory design of a versatile Intranet application currently in use at the Division of Computer Aided Design, Luleå University of Technology in Sweden.

    Effective development of dynamic systems: a structured approach1999Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This licentiate thesis deals with effective simulation of multibody dynamic systems in the product development process. Previous work to make simulation more effective has concentrated on developing faster calculation methods. Instead, this approach is to make the process of multibody dynamics simulation more effective by structuring of products, simulation models and their usage. Efforts have been made to clarify how computer tools are used in product development in industry today. Insight into the two domains of product development and multibody dynamics is given. These domains have traditionally been separated but the introduction of concurrent engineering and faster computers puts new demands on the integration of computer support and analysis in the development process. A proposal for performing the multibody dynamics methodology in a modular way in the product development process is given based on the performed work.

    Multibody dynamic simulation in product development2001Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis deals with multibody dynamic simulation of mechanical systems in the product development process. The approach is to make the process of multibody dynamics simulation more efficient by structuring of the simulation, simulation models and their usage. Previous work has concentrated on developing faster calculation methods and more specialised simulation software. Efforts have been made to clarify how computer tools and multibody dynamic analysis methods are used in product development in industry today. Insight into the knowledge domains of product development and multibody dynamics is given together with an introduction to the area of distributed simulation, modularisation techniques and nonlinear analysis. The mentioned domains have traditionally been separated but the introduction of concurrent engineering and faster computers puts new demands on the need for integration of computer support and analysis in the development process. The performed work is to be seen as cross-functional work in order to bring different domains together for the sake of a better total product development. The applications areas used in the work are all within vehicle system dynamics. A proposal for performing the multibody dynamics methodology in a distributed and modular way in the product development process is given based on the performed work together with a prototype implementation.

    Simulering av dynamiska system vid produktutveckling2001Ingår i: Mekanisten, ISSN 0284-9763, nr 2, s. 46-49Artikel i tidskrift (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    Efforts have been made to clarify how computer tools and multibody dynamic analysis methods are used in product development in industry today. Insight into the knowledge domains of product development and multibody dynamics is given together with an introduction to the areas of distributed simulation, modularisation techniques and non-linear analysis. The mentioned domains have traditionally been separated but the introduction of concurrent engineering and faster computers puts new demands on the need for integration of computer support and analysis in the development process. The performed work is to be seen as cross-functional work in order to bring different domains together for the sake of a better total product development. The application areas used in the work are all within vehicle system dynamics. Clarification of the multibody dynamic simulation methodology has been made in the performed work. A proposal for performing the multibody dynamics methodology in a distributed and modular way in the product development process is given together with a prototype implementation. The prototype system facilitates the idea of distributing analysis possibilities from simulation experts to engineers, hereby increasing the simulation usage in product development. The purpose is to arrive at a simulation driven design rather than a simulation verified design
