    Assessment of team based innovation in a Product Service System development process2011In: Research into Design: Supporting Sustainable Product Development / [ed] Amaresh Chakrabarti, Bangalore, India: Research Publishing Services, 2011, p. 711-718Conference paper (Refereed)
    Abstract [en]

    Innovation is often measured based on how the product performs on the market. This makes it difficult to measure the performance of a team since the time to develop a product may take several years. In this paper we show the importance of creating a common ground and facilitation in a team, two aspects that is not easy measure, but should be assessed. We also discuss innovation on three interrelated organizational levels, the operational, which is the development team and in focus in this paper, the managerial and the strategic level. We found that companies need indicators to measure and/or assess performance on all three levels and thatmore research is needed to find the inter-links between the levels to prescribe measures and assessment points.

    Analysing the effects of value drivers and knowledge maturity in preliminary design decision-making.2015In: ICED 15, VOL 10: DESIGN INFORMATION AND KNOWLEDGE MANAGEMENT, Design Society , 2015Conference paper (Refereed)
    Abstract [en]

    The paper presents the results of a three-days experiment to test the use of informationfrom a value assessment model and from a knowledge maturity scale in decisionmakingin preliminary design. A visual analogue scale was used to collect individualinformation from designers through questionnaires. Bivariate statistical analysis wasapplied to study the correlations between both the use of value drivers and knowledgematurity and the designers' awareness of the design problem to be addressed. Resultsshow that value drivers and knowledge maturity information increase the decisionmakers’ awareness of (1) the different perceptions of design team members about theneeds to be satisfied and (2) the technical solution to be developed in the productconcept under consideration.

    Value-driven product service systems development: Methods and industrial applications2016In: CIRP - Journal of Manufacturing Science and Technology, ISSN 1755-5817, E-ISSN 1878-0016, Vol. 15, p. 42-55Article in journal (Refereed)
    Abstract [en]

    In recent times a service-dominant logic is permeating the design of complex systems. However, in spite of their appeal, initiatives such as Product Service Systems (PSS) have not become mainstream, and methods are lacking to support this transition. This paper argues that methodological guidance, as well as tools for decision support, may be found in the research field of Value Driven Design (VDD), which originates in the realm of Systems Engineering. The paper objective is to elaborate on gaps and opportunities for cross-pollination between VDD and PSS. The results of a systematic review of methods and tools for design decision support highlight the opportunity for introducing optimization models derived from VDD in the PSS design process, while the latter can enrich VDD research with a more qualitative value assessment logic. The paper summarizes this integration in a methodological approach, and exemplifies its application in case studies mainly from the aerospace and road construction equipment sector.

    Value-oriented concept selection in aero-engine sub-systems design: the EVOKE approach2013In: 23rd Annual International Symposium of the International Council on Systems Engineering, INCOSE 2013: Philadelphia, PA, 24-27 June 2013, 2013, Vol. 2, p. 977-991Conference paper (Refereed)
    Abstract [en]

    The design of complex systems requires detailed analysis to be moved earlier in the design process. Value Driven Design methodologies extend the Requirements Management and Systems Engineering processes to reduce time and costs needed to identify the right solution direction to be pursued in detailed design. Emerging from the findings of an EU FP7 research project, the paper describes an approach for preliminary concept selection, named EVOKE, that uses value as a basis for decision. EVOKE enables quick value analysis to be executed by component manufacturers by taking as input a set of value dimensions and drivers communicated by the system integrators, together with information about the high-level engineering characteristics of the sub-systems under consideration. The approach and its technological enablers are described in detail through the use of a case study related to the design of new intermediate compressor case for turbofan engines.

    Knowledge Enabled Engineering2015In: International Workshop of Advanced Manufacturing and Automation, Trans Tech Publications Inc., 2015Conference paper (Refereed)
    Abstract [en]

    The development of complex product-service combinations challenges the existing practices for engineering knowledge management. The objective of the paper is to highlight how such practices need to change to meet the engineers’ demand for knowledge when developing “functions” instead of merely hardware. It further proposes Knowledge Enabled Engineering (KEE) as an umbrella term that collects engineering knowledge management methods and tools inspired by the second wave of knowledge management, and that are aimed to meet needs of today’s modern knowledge workers in engineering organizations. The current state of readiness of these approaches is eventually described together with results from verification and validation activities.

    Towards assessing the value of aerospace components: a conceptual scenario2011In: Impacting society through engineering design: ICED 11 København, the 18th International Conference on Engineering Design; 15th - 18th August 2011, Technical University of Denmark (DTU), Copenhagen, Denmark; proceedings volumes / [ed] Steve Culley; Ben Hicks; Tim McAloone; T.J. Howard, Glasgow: Design Research Society, 2011, Vol. 9 : Design methods and tools, p. 226-235Conference paper (Refereed)
    Abstract [en]

    The development of complex products, characterized by long lifecycles and deep supply chains, requires enhanced capabilities to assess, in an early design stage, the value of a solution not merely from a requirement fulfillment perspective. The paper proposes a conceptual scenario, described in terms of activities, inputs, outputs, actors and mechanisms, which details how aircraft components can be developed and assessed with a focus on their value contribution at system level. The scenario proposes a set of methodological and technological tools needed to enable value assessment in preliminary design, and has been created and preliminary validated together with major European aerospace manufacturers. The importance of being able to communicate the lifecycle value contribution of design solutions during the development work emerged clearly from the study. In this spirit, an approach to visualize such contribution directly in a 3D CAD model (across a set of value criteria, dimensions and drivers) has been proposed and it is currently under development.

    Pilot specifications definition guidelines for the implementation of a KEE solution in the aeronautical domain2008In: CIRP Design Conference 2008 / [ed] Fred J. A. M. van Houten, Laboratory of Design, Production and Management, Faculty of Engineering Technology, Univ. of Twente , 2008Conference paper (Refereed)
    Abstract [en]

    Designing and implementing a Knowledge Management System (KMS) in a Virtual Enterprise is a labour intensive and risky task. Solution prototypes (Pilots) are usually built to verify system effectiveness prior to final implementation. The paper proposes a methodology to guide this Pilot specifications definition process. These guidelines support engineers and knowledge experts in collaboratively defining functionalities, services, software components and performance indicators of the prototype. The methodology has been conceived and applied within the European project VIVACE, to support the development of a Knowledge Enabled Engineering (KEE) system in the aeronautical domain.

    Pilot specifications definition guidelines for the implementation of a KEE solution in the aeronautical domain2008In: 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 , 2008Conference paper (Refereed)
    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.

    Social technologies for cross-functional product development: SWOT analysis and implications2012In: Proceedings of the Annual Hawaii International Conference on System Sciences, Los Alamos, CA, USA: IEEE conference proceedings, 2012, Vol. 45, p. 3918-3927Conference paper (Refereed)
    Abstract [en]

    Innovation is triggered by the cross-pollination of fields and disciplines. In product development, this means bringing together people with different expertise to develop breakthrough product and service offers. In spite of their great potential, cross-functional efforts are not yet adequately supported from a knowledge perspective, asking for a more open and bottom-up open approach to knowledge management. The paper aims to investigate how social technologies can enhance collaboration and knowledge sharing in complex, cross-functional and cross-organizational product development projects. It initially highlights the role of weak ties as enablers for more innovative design processes, especially when manufacturing companies move towards developing integrated offers mixing hardware, software and services. Emerging from data collected in two case studies conducted within the European aeronautical industry, it applies the Strength-Weaknesses-Opportunities-Threats (SWOT) framework to highlight how tools such as wikis, blogs, forum and microblogs can shorten and increase the quality of early design decisions. Furthermore it elaborates on how the design team can enhance its perception of the needs to be addressed and leverage its capability to develop solutions for the task at hand.

    A methodology for KEE systems target cascading2008In: Proceedings of the 7th International Symposium on Tools and Methods of Competitive Engineering - TMCE 2008 / [ed] I. Horváth and Z. Rusák, Delft University of Technology , 2008, Vol. 2Conference paper (Refereed)
    Abstract [en]

    The main aim of this paper is to present a methodology developed within the European Project VIVACE to guide the design and implementation of a Knowledge Enabled Engineering (KEE) system in a Virtual Enterprise. The proposed methodology tries to overcome some of the limitations which characterise traditional methods for Target Cascading, promoting a more collaborative and iterative approach to derive system specifications (in terms of advanced knowledge functionalities) from initial high-level targets. Social and behavioural aspects of Knowledge Management play a crucial role when many different users, knowledge experts, and process owners are involved in the Knowledge Management System (KMS) development. A well designed methodology is needed, therefore, to enhance communication and information sharing among design teams, to promote requirements merging and to take care both of the technological and behavioural aspects of the implementation. Initial business targets have been step-by-step decomposed into a set of sub-problems (Service Requirements, Knowledge Issues, and Knowledge Challenges) in the form of simple sentences in natural language. Then Quality Function Deployment (QFD) matrixes have been used to identify the set of functionalities to be implemented in the system, addressing the most important knowledge-related problems outlined in the cascading activity.

    Performance Measurement Framework for Product-Service System Development: A Balanced Scorecard Approach2013In: International Journal of Technology Intelligence and Planning (IJTIP), ISSN 1740-2832, E-ISSN 1740-2840, Vol. 9, no 2, p. 146-164Article in journal (Refereed)
    Abstract [en]

    The Product-Service System (PSS) paradigm is recognized as a means for companies to increase the value perceived by the customers, thus gaining competitive advantage beyond traditional ‘pure product’ offerings. Researches have shown the necessity to rethink design processes in a PSS context, in order to drive the successful integration of product and service features in early design phases. In the last few years, several new approaches have been proposed, however little attention has been paid on how to translate these approaches into action and on how to evaluate their performances and effectiveness. This paper proposes a framework for analysing the performances in PSS development process using a Balanced Scorecard approach, as a tool to guide the implementation and the evaluation of new methods and tools in the early design phases. The paper starts with discussing the main challenges encountered when designing PSS, and then, adopting an aerospace industry as an example, to propose an application of the Balance Scorecard for the implementation and measurement of PSS development. Finally, the main pros and cons are discussed in relation to strengths and weaknesses of using balanced scorecard in PSS development. The framework developed in this paper can provide a useful guidance for the managers in measuring the performances of the PSS development process.

    Many companies have been using lessons learned practices as one oftheir key knowledge management initiatives to capitalize on past experiences.For product development companies, learning from product lifecycle phasesgives a true competitive advantage to improve the next generation of products.However, companies are still struggling in capturing and sharing lessonslearned and applying them in new situations. Based on this consideration, thepaper proposes a video-based approach–using social media technologies–as away to leverage continuous capturing and sharing lessons learned from productlifecycle phases to design practices. The paper presents the findings of a casestudy within the aerospace industry, which investigates the current industrialpractices with regard to experience feedback, and illustrates the implementationof a video-based approach. Further, the conceptual mock-up of video-based lessons learned sharing portal and its social platform that are aimed to support the design practices are illustrated.

Hence, companies are increasingly investigating how to leverage knowledge management practices to enhance their dynamic learning capabilities to achieve continuous process improvements. Manyresearchers assert that lessons learned practices are possible ways for organizational learning, which allows for continuous capturing and sharing of experiential knowledge across boundaries in order to learn both from mistakes and successes. However, many organizations fall short in capturing and sharing lessons from projects and applying them in new situations. The purpose of this paper is to propose a video-based approach and related guidelines for capturing and sharing lessons learned in a dynamic manner across functional and organizational boundaries. Based on laboratory experiments as well as validation activities conducted in collaboration with an aerospace manufacturer, this papercompares the video-based approach with a more traditional text-based approach of documenting lessons learned from projects. The paper describes the results of testing activities conducted with a video-based lessons learned prototype and the authors reflect on its implications for design practice management in the aerospace industry.

    Abstract [en]

    This paper discusses views on decision support in product development to identify factors of relevance when designing computer-based decision sup- port for total offers. Providing services in form of physical artefacts of- fered as ‘functions per unit’ is at the heart of total offers. Total offers gain access to possibilities to ‘design in’ value added characteristics into the physical artefact, e.g., maintenance, monitoring, training, remanufacture. Contemporary computer tools seem to be insufficient to support a GO/NO GO decision for total offers. 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 improve the solution space.

    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 quest for knowledge?2011Report (Other academic)
    Abstract [en]

    Today, a new knowledge economy and more service-based offerings are commonly mentioned as a challenge for manufacturing companies. This challenge addresses the companies’ knowledge base and the traditional engineering expertise areas. The report starts from an assumption that there are differences in how knowledge is managed, as well as differences in the intentions to why it is managed. Based on this assumption, the purpose in the report is two-folded. First, the purpose is to conceptualize different facets of knowledge within a framework of technical product development. Second, the purpose is that the report serves as a trigger for discussions and reflections on existing practices in industrial workshops. So, despite that the report does not provide the “right” answers to these questions; they still guide the work in our research:• What is actually managed in every-day engineering project work?• And, for what purposes?The work accounted for in the report comes from a literature review and our jointefforts in understanding the research area from a theoretical perspective. First general views on knowledge is presented, including its classification in different ways, compared to information and data, as well as its division into tacit and explicit knowledge, or practical skills and theoretical knowledge. Human factors, including how people search for information, is also presented. Then a more explicit focus on technical knowledge is presented, showing the shift from knowledge as an artefact to a social and personal perspective in recent years. This also encompasses discussing the capabilities and knowledge of an engineer. A contribution of this report is the conceptualization of different facets of engineering knowledge; especially the more social aspects of engineering knowledge have been highlighted.

    Abstract [en]

    A new vision in manufacturing is to develop product-service integrated value solutions. Today, few firms have fully realized this vision because they are not able to support the reasoning in the early stages of design. The purpose of this paper is to discuss engineers' cognitive challenge when replacing the core product rationale with value logic. The paper problematizes engineering design by dividing knowledge into the categories technically constructed (explicit) and socially constructed (tacit). In doing so, this study contributes the assumed effects of a perspective shift that could guide the development of computational tools.

    Manufacturing industry is expressing an increased interest in knowledge management due to the extension towards aservice provision business model. However, the inclusion of softer service aspects indicates that the common view onknowledge management as a way to control and monitor a technical process have limitations. Sharing expertise is anadditional way of managing knowledge particularly with the intentions to make experience based knowledgeorganizational available. By studying product developers’ daily work, especially how they perceive that they apply andshare knowledge, we problematize knowledge activities in product-service development to discuss the establishedknowledge management activities. The paper suggests some considerations to support the development of aknowledge base for product-service design.

    Knowledge engineering in the virtual enterprise: exploring a maturity-based decision support2007Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    In product development, lead-time reduction, cost reduction, and quality improvement are issues that companies want to improve on to increase competitiveness. One recent approach to reach this - particularly in the aerospace industry where the complexity of product offers is steadily increasing - is to manage risk by forming virtual enterprises. A virtual enterprise is a network of partner companies that join on equal terms when an opportunity arises to develop a product offer, e.g. a jet engine offer, in a more agile manner than if any of the partners would realise it by themselves. They therefore team up to share risk, investment and resources - to in return also share revenue and profit. A driver for the formation of the virtual enterprise is the ability to effectively utilise partner knowledge assets. However, when sharing and managing knowledge effectively across the virtual enterprise, current practices have yet to evolve to meet the needs of knowledge workers, who may come from different aerospace companies, have different roles, belong to different disciplines and that may also be situated in geographically dispersed locations.

    Improving product development includes allowing developers from all disciplines to know - as early as possible in the product development process - more about the customer needs, the desired product properties, and the downstream impact of the decisions they choose to make throughout the process. Knowing about the impact in downstream phases would allow for significant time and cost savings due to the avoidance of unnecessary and expensive rework that would otherwise occur much further on in the product's life cycle.

    Among other things, a virtual enterprise can start organising and mapping the knowledge assets available in their teams, and information overload can be managed by assuring that the right knowledge ends up with the right person, to mention but a few things that can facilitate the everyday work of engineers and their colleagues. When working in a product development project, the virtual enterprise needs to assess the quality of the created knowledge as early as possible to devise the correct actions early. In this thesis, a Gated Maturity Assessment technique including the concept of knowledge maturity has been developed as an example of an improved stage-gate decision-making process. With this approach development teams are able to assess the knowledge maturity level in the content and rationale that is put forward as a basis for a decision - as opposed to only assessing the raw data of the results (i.e. thrust, weight, fuel burn, etc.). Knowledge maturity is used to support decision makers when in the process of assessing a decision base to make a decision whether to go ahead, abort the process, or order rework to be done. Naturally, if the decision base is poor, a decision to go ahead should probably not be taken, as the consequences might be negative. In assessing maturity, decision makers can determine at decision points if the knowledge base is good enough to move forward to the next step in the jet engine component design, if there is need for rework, and what specific areas need to be improved. Decision makers can divert and focus resources to areas of importance due to, for instance, too low maturity levels.

    Knowledge maturity is a way to - using a criteria scale that prescribes the knowledge needed at each level - help development teams assess and visualise how well they know what they know, and subsequently, what they need to know. This thesis explores the feasibility of using knowledge maturity as a way of supporting knowledge engineering in the context of a development process in aeronautics.

    Knowledge maturity as decision support in stage-gate product development: a case from the aerospace industry2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In today’s fast-paced industry where fight for market share is fierce and reaching the market ahead of competition imperative, product development is a target for lead-time reductions. In this context, in product development in stage-gate processes, decisions need to be made even though knowledge and information are scarce and flawed. The challenge is how to support the decisions that are made in light of uncertainty and ambiguity. The thesis moves from analysing the role of the stage-gate process within the aerospace industry. The stage-gate process was more than a decision making mechanism, and instead a mechanism that facilitated communication, discussion and knowledge sharing between team members, as well as supported knowledge creation and shaping of the boundaries between people’s different perceptions of the knowledge base. However, the communicative and negotiative function of the stage-gate was highly dependent on the ability of the participating individuals to reflect on the status and quality of the available knowledge assets used throughout the process. To make this reflective activity an explicit part of the stage-gate practice, this thesis proposes the application of a knowledge maturity concept at the gates to raise the decision makers’ awareness of the status of the knowledge assets handled at the decision point. The knowledge maturity concept considers three basic dimensions: input, method/tool and experience/expertise in assessing the knowledge base maturity. The scale is intended to act as a boundary object, facilitating the knowledge creation process by highlighting the current status of the knowledge base and making stakeholders aware of the nature of the project’s uncertainties and ambiguities. In the knowledge maturity concept, its purpose is to support design teams at the gates in taking appropriate action, mitigating risk and focusing their efforts on improving the knowledge assets where it is needed most, regarding the situation at hand and, finally, to make more confident decisions.The thesis was developed within the EU FP6 VIVACE (Value Improvement through a Virtual Aeronautical Collaborative Enterprise) and EU FP7 CRESCENDO (Collaborative and Robust Engineering using Simulation Capability Enabling Next Design Optimisation) projects, and within the Faste Laboratory, a VINNOVA Excellence Centre involving partners from the Swedish manufacturing industry.

    Managing Uncertainty and Ambiguity in Gates: Decision Making in Aerospace Product Development2014In: International Journal of Innovation and Technology Management (IJITM), ISSN 0219-8770, Vol. 11, no 2Article in journal (Refereed)
    Abstract [en]

    This paper investigates decision making in the stage-gate process used by an aerospace manufacturer. More specifically, it focuses on the way decision makers deal with uncertainties and ambiguities when making decisions. The stage-gate model was found to be a discussion trigger - a boundary negotiating artefact - through which stakeholders bring issues to the table, reflect on uncertainties, and decide in what areas more knowledge is needed. Managers should be aware that the knowledge base might not always be perfect and should make use of the sensemaking capabilities of the stage-gate model and the gate meeting to mitigate and improve the knowledge base. This paper elaborates on formalized knowledge-based criteria so as to support this evaluation of the knowledge base.

    Reverse Engineered Design Automation: Applying Knowledge Based Engineering Techniques to a Case of Automotive Fixtures Design Configuration2019In: Proceedings of the Design Society: International Conference on Engineering Design, Cambridge University Press, 2019, Vol. 1, p. 1583-1592Conference paper (Refereed)
    Abstract [en]

    In the production of automotive body components, fixtures are an important part of the ongoing work on geometrical assurance. The fixture is uniquely defined for each component, and the design and configuration of these are time-consuming and takes a lot of effort. The objective with this paper is to explore the use of a design automation approach and application to semi-automate the configuration process of the fixture product. The paper presents an approach to automate the configuration of the fixtures in a flexible way, by reverse engineering the configuration of the fixture product from a generic blueprint that represents the expected outcome of the process, using a knowledge-based engineering approach applied to a computer aided design (CAD) environment. A reverse-engineered design automation toolbox for a CAD-software is developed. The toolbox is developed to lead a user through the configuration process, in the way that the experts want it done, end-to-end, making use of some unconventional solutions from a design automation perspective.

    Towards assessing the value of aerospace components: a conceptual scenario2011In: mpacting society through engineering design: ICED 11 København, the 18th International Conference on Engineering Design / [ed] ve Culley, Ben Hicks, Tim McAloone, T.J. Howard, Glasgow, UK: The Design Society, 2011, Vol. 18, p. 226-235Conference paper (Refereed)
    Abstract [en]

    The development of complex products, characterized by long lifecycles and deep supply chains, requires enhanced capabilities to assess, in an early design stage, the value of a solution not merely from a requirement fulfillment perspective. The paper proposes a conceptual scenario, described in terms of activities, inputs, outputs, actors and mechanisms, which details how aircraft components can be developed and assessed with a focus on their value contribution at system level. The scenario proposes a set of methodological and technological tools needed to enable value assessment in preliminary design, and has been created and preliminary validated together with major European aerospace manufacturers. The importance of being able to communicate the lifecycle value contribution of design solutions during the development work emerged clearly from the study. In this spirit, an approach to visualize such contribution directly in a 3D CAD model (across a set of value criteria, dimensions and drivers) has been proposed and it is currently under development.

    Urban Mining as a Case for PSS2016In: PRODUCT-SERVICE SYSTEMS ACROSS LIFE CYCLE / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, p. 460-465Conference paper (Refereed)
    Abstract [en]

    Reports about the depletion and pollutant of the earth by human interference and the increasing need for urbanised areas require us to think differently about how we go about achieving this increased urbanisation. In this context, urban mining, where demolition sites are mined for increased recycling and value extraction. Due to high specialisation of construction equipment for this context, as well as sustainability being an important factor, product-service systems are suggested as a way forward in this area. This paper presents key topics that needs to be addressed when developing sustainable product-service systems for the urban mining segment. The idea is to transform from a traditional construction and demolition perspective towards a PSS-based construction product for an urban mining environment, incorporating a circular economy perspective. A modification to the common business model notation of business model canvas, with guiding questions is suggested. Opportunities for improved sustainability lies both in application – within an urban mining site – and in the enabling technology – when technology is specialised, owned by the provider, and utilised by multiple partners.

    Abstract [en]

    An extension towards a service perspective in manufacturing firms challenge decision making in early development phases. This addition in business models challenges the established knowledge base, which is focused on product aspects. A service perspective makes it necessary to assess the team's competences in another way. The knowledge maturity scales presented in this paper stems from a method to judge technology readiness, yet the knowledge perspective adopted highlights the issue of whether this approach is readily adopted or not. In this paper, a pragmatic view of the term knowledge, as found in previous empirical data, is used to discuss and propose a way to visualize the current knowledge state in a development team. The paper concludes on a rationale for visualization of knowledge maturity. Based on this, further improvement of the scales to support a service perspective on products can be done.

    Abstract [en]

    Today, a new knowledge economy and more service-based offerings are commonly mentioned as a challenge for manufacturing companies. This challenge addresses the companies’ knowledge base and the traditional engineering expertise areas. The report starts from an assumption that there are differences in how knowledge is managed, as well as differences in the intentions to why it is managed. Based on this assumption, the purpose in the report is two-folded. First, the purpose is to conceptualize different facets of knowledge within a framework of technical product development. Second, the purpose is that the report serves as a trigger for discussions and reflections on existing practices in industrial workshops. So, despite that the report does not provide the “right” answers to these questions; they still guide the work in our research:• What is actually managed in every-day engineering project work?• And, for what purposes?The work accounted for in the report comes from a literature review and our jointefforts in understanding the research area from a theoretical perspective. First general views on knowledge is presented, including its classification in different ways, compared to information and data, as well as its division into tacit and explicit knowledge, or practical skills and theoretical knowledge. Human factors, including how people search for information, is also presented. Then a more explicit focus on technical knowledge is presented, showing the shift from knowledge as an artefact to a social and personal perspective in recent years. This also encompasses discussing the capabilities and knowledge of an engineer. A contribution of this report is the conceptualization of different facets of engineering knowledge; especially the more social aspects of engineering knowledge have been highlighted.

    Optimizing Genetic Algorithms for Time Critical Problems2003Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Genetic algorithms have a lot of properties that makes it a good choice when one needs to solve very complicated problems. The performance of genetic algorithms is affected by the parameters that are used. Optimization of the parameters for the genetic algorithm is one of the most popular research fields of genetic algorithms. One of the reasons for this is because of the complicated relation between the parameters and factors such as the complexity of the problem. This thesis describes what happens when time constraints are added to this problem. One of the most important parameters is population size and we have found by testing a well known set of optimization benchmark problems that the optimal population size is not the same when time constraints were involved.

    Knowledge maturity as a means to support decision making during product-service systems development projects in the aerospace sector2011In: Project Management Journal, ISSN 8756-9728, E-ISSN 1938-9507, Vol. 42, no 2, p. 32-50Article in journal (Refereed)
    Abstract [en]

    Streamlining new product development forces companies to make decisions on preliminary information. This paper considers this challenge within the context of project management in the aerospace sector, and in particular the development of product-service systems.  The concept of knowledge maturity is explored as a means to provide practical decision support, which increases decision makers' awareness of the knowledge base and supports cross-boundary discussions on the perceived maturity of available knowledge, thereby identifying and mitigating limitations. Requirements are elicited from previous research on knowledge maturity in the aerospace industry and a knowledge maturity model is developed through five industry-based workshops.

    Enhancing intra-cognitive communication between engineering designers and operators: a case study in the laser welding industry2012In: Proceedings of the 3rd IEEE International Conference on Cognitive Communications: CogInfoCom 2012, Piscataway, NJ: IEEE Communications Society, 2012, p. 493-497Conference paper (Refereed)
    Abstract [en]

    In manufacturing, metal parts can be joined using a laser as a welding tool, i.e. laser welding. Despite huge amount of research over the years, the process is neither sufficiently understood nor mathematically predictable. This study aims to holistically analyze the knowledge management issues occurring in laser welding. Emerging from observations and semi-structured interviews from industry and academy, the complexity and the criticalities of the process as well as the current knowledge transfers is explained and analyzed, using a knowledge lifecycle framework as a reference. Besides enhanced awareness of the limiting issues, information and knowledge visualization, e.g. knowledge maps, is identified as a key for progress in the community. The Matrix Flow Chart is suggested as an alternative descaled map of process changes.

    Virtual Meeting Interoperability: Discussing the need of support for heterogeneous meeting environments2006In: Proceedings of the Fourth IASTED International Conference on Knowledge Sharing and Collaborative Engineering / [ed] M. Boumedine, C. Touzet, 2006, Vol. 4, p. 92-97, article id 532-076Conference paper (Refereed)
    Abstract [en]

    With more projects in today’s industry being global it is important to support the people collaborating in these projects. Travel is expensive and time consuming and is not viable in the long run. Although some travel is necessary it is important for people to meet virtually instead. In many cases it is difficult for companies to collaborate because they do not use the same tools for these virtual meetings. Due to restrictions with IT security it is also difficult and expensive to implement every new tool their partner companies use. One solution could be a portal that facilitates connecting users with different virtual meeting tools. Using Web Services to bridge the different protocols it would be possible to connect two software packages that are using different standards for virtual meetings. With a tool as this it would be possible for chosen companies to collaborate closely online although they have incompatible software packages. Companies can select their solutions on the basis of their needs and do not have to implement a new solution or modify their existing setup to accommodate new partner needs. Finally, people would only need to learn the one tool which is available in their own company.

    Knowledge enabled engineering - knowledge lifecycle approach2007Conference paper (Refereed)
    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.
