    A model-driven decision arena: Augmenting decision making in early design2018In: Norddesign conference proceedings, The Design Society, 2018Conference paper (Refereed)
    Abstract [en]

    A wide variety of expert competencies, transcending traditional disciplines, are needed to foresee and evaluate the impact of decisions in the conceptual phase of engineering design. Where this previously was a trade-off regarding design and development of the pure physical artefact it is now a complex ambiguity game involving all disciplines touching a solution during its lifecycle, due to the movement towards integrated product-service solutions. Gathering the involved, normally diverse, group of stakeholders in a collaborative setting for design exploration exercises, sharing knowledge and values, is believed to augment decision making ability in early design. A model-driven environment for collaborative decision making is proposed as a solution that potentially may help harvesting these benefits. In this environment stakeholders interact with each other using digital models, model generated information, simulation data and product data collected in the field in order to evaluate design proposals by playing out potential usage scenarios and investigating cause and effect relationships. Initial work on conceptualizing, developing, and testing such an environment is done through a pilot study based on two industrial use cases. The development process iteratively unveils demands and constraints related to the environment. These discoveries go hand in hand with developing an infrastructure regarding both hardware and software as well as required human resources in a functional environment. Fully realizing the envisioned model-driven environment for collaborative decision making entails new ways of working requiring new knowledge as well as technological innovation. In that aspect, environment infrastructure and usage are elaborated on and direction for further research and development is indicated.

    Data Mining through Early Experience Prototyping: A step towards Data Driven Product Service System Design2018In: IFAC PAPERSONLINE, Elsevier, 2018, Vol. 51, no 11, p. 1095-1100, article id 11Conference paper (Refereed)
    Abstract [en]

    The construction industry is ripe for disruption through innovative solutions that provide added productivity. Equipment manufacturers are attempting to disrupt their industry with investments in autonomy, electrification and product-service system business models. Designing solutions that will operate in completely new systems or modify an existing complex system require new approaches to address the uncertainty of system impacts. An iterative approach can help tackle ambiguity through cyclical validation of design decisions. Data mining in each cycle adds a quantitative dimension to the rationale of decision making, but data is sparse and difficult to collect in parallel with design of theoretical product-service systems operating in future scenarios. This can be combated using experiential prototyping techniques to design flexible infrastructure that supports contextualized data gathering in a variety of focused design sprints using Design, Build and Test approach. The intricacy of designing innovative solutions to increase productivity in the construction industry can be untangled by framing aspects of the problem in small sprints and testing them in a contextualized setting built to generate functional data to drive design.

    Design and Frugal Innovations: Three roles of resource-poor people2018In: Proceedings of the International Design Conference / [ed] D. Marjanović, M. Štorga, S. Škec, N. Bojčetić, N. Pavković, The Design Society, 2018, p. 2657-2668Conference paper (Refereed)
    Abstract [en]

    Design is imperative to satisfy needs of people in resource-limited societies. Many design studies have been carried out in the context of such societies in developing countries, and are discussed under names such as humanitarian engineering, frugal innovations, appropriate technology, design at the Base of the Pyramid, design for development, etc. In this paper, we review a wide range of literature, with close analysis of 30 design studies in this field to understand how marginalised people were engaged and positioned in those studies and to plan for future research in this field.

    Most Influential Qualities in Creating Satisfaction Among the Users of Health Information Systems: A Study in Seven EU Countries2018In: JMIR Medical InformaticsArticle in journal (Refereed)
    Abstract [en]

    Background:

    Several models suggest how the qualities of a product or service influence user satisfaction. Models, such as the Customer Satisfaction Index (CSI), Technology Acceptance Model (TAM), and Delone and McLean Information Systems Success (D&M IS), demonstrate those relations and have been used in the context of health information systems.

    Objective:

    We want to investigate which qualities foster greater satisfaction among patient and professional users. In addition, we are interested in knowing to what extent improvement in those qualities can explain user satisfaction and if this makes user satisfaction a proxy indicator of those qualities.

    Methods:

    The Unified eValuation using ONtology (UVON) method was utilised to construct an ontology of the required qualities for seven e-health applications being developed in the FI-STAR project, a European Union (EU) project in e-health. The e-health applications were deployed across seven EU countries. The ontology included and unified the required qualities of those systems together with the aspects suggested by the Model for ASsessment of Telemedicine applications (MAST) evaluation framework. Two similar questionnaires, for 87 patient users and 31 health professional users, were elicited from the ontology. In the questionnaires, user was asked if the system has improved the specified qualities and if the user was satisfied with the system. The results were analysed using Kendall correlation coefficients matrices, incorporating the quality and satisfaction aspects. For the next step, two Partial Least Squares Structural Equation Modelling (PLS-SEM) path models were developed using the quality and satisfaction measure variables and the latent construct variables that were suggested by the UVON method.

    Results:

    Most of the quality aspects grouped by the UVON method are highly correlated. Strong correlations in each group suggest that the grouped qualities can be measures which reflect a latent quality construct. The PLS-SEM path analysis for the patients reveals that the effectiveness, safety, and efficiency of treatment provided by the system are the most influential qualities in achieving and predicting user satisfaction. For the professional users, effectiveness and affordability are the most influential. The parameters of the PLS-SEM that are calculated allow for the measurement of a user satisfaction index similar to CSI for similar health information systems.

    Conclusions:

    For both patients and professionals, the effectiveness of systems highly contributes to their satisfaction. Patients care about improvements in safety and efficiency, while professionals care about improvements in the affordability of treatments with health information systems. User satisfaction is reflected more in the users' evaluation of system output and fulfilment of expectations, but slightly less in how far the system is from ideal. Investigating satisfaction scores can be a simple, fast way to infer if the system has improved the abovementioned qualities in treatment and care.

    Competitiveness and Sustainability Effects of Cars and their Business Models in Swedish Small Town Regions2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 140, no Part 1, p. 333-348Article in journal (Refereed)
    Abstract [en]

    This article aims to develop and test a new approach for comparing sustainability effects (mainly approximated through CO2 emissions) and the total cost of ownership of various business models (Regular Purchasing, Car Pooling, Car Leasing, and Taxiing) applied to private cars with different energy carriers (Biogas, Ethanol, Gasoline, Plug-in Hybrid, and Electric). The results indicate that, out of all of the vehicles, electric vehicles are the most competitive—from both an ecological and economic perspective. Moreover, of all of the business models, Car Pooling is the most competitive when driving short to medium distances, reducing CO2 emissions by 20-40% compared with Regular Purchasing. Meanwhile, Car Leasing emits the same amount of CO2 emissions as Regular Purchasing if both are driven the same number of kilometers per year. The results also indicate that, from a cost effectiveness perspective, people who travel less than 2000 km per year should primarily consider using Taxis or similar services, while Car Pooling is most cost effective for those who travel from 2000 to 8500 km. For those who travel between 8500 and 13500 km per year, Car Leasing is the most cost effective, and Regular Purchasing is the best option above 13500 km per year. If most car owners were to accept and adapt to this identified need for a market move towards Car Pooling with Electric Vehicles, necessary transportation could be ensured while significantly reducing the number of cars on the road, whether from Regular Purchasing or Car Leasing, as well as those that run on fossil fuel. This, in turn, would result in less fossil fuel use, fewer emissions, and decreased negative effects on human health.

    Data Mining in Product Service Systems Design: Literature Review and Research Questions2017In: Procedia CIRP / [ed] Tim C. McAloone, Daniela C.A. Pigosso, Niels Henrik Mortensen and Yoshiki Shimomura, Elsevier, 2017, Vol. 64, p. 306-311Conference paper (Refereed)
    Abstract [en]

    The paper presents a literature review about data mining applications in Product/Service-Systems (PSS) design. A systematic literature review, combined with snowballing techniques, has been run to identify relevant contributions in the area. The analysis has focused on the categorization of the contributions according to their impact on the PSS design process and according to their theoretical or empirical nature. A picture of the different research achievements for each stage of the PSS design process have been drawn, identifying the research gaps in respect to the challenges of PSS design. Based on the analysis the paper proposes a set of research questions for each PSS design stage with the intent of facilitating the application of data mining techniques in PSS design, and ultimately push forward the state of the art.

    Exploration of Simulation-Driven Support Tools for Sustainable Product Development2017In: Procedia CIRP / [ed] Tim C. McAloone, Daniela C.A. Pigosso, Niels Henrik Mortensen and Yoshiki Shimomura, Elsevier, 2017, Vol. 64, p. 271-276Conference paper (Refereed)
    Abstract [en]

    Global society is encountering many challenges such as climate change, resource depletion, etc., which comes with a set of challenges and opportunities for businesses. Applied research in operational tools and methods that support sustainable product- and service systems innovation, aims to strengthen businesses to overcome these challenges. In recent years, several tools and methods have been developed in the sustainable product development field with focus on modelling and digitalization. This paper explores how sustainability has been integrated in modelling and simulation, and presents results from a literature review with the purpose of highlighting opportunities and challenges in the field. Furthermore, an initial model-based engineering support toolbox (MBE) is presented, with focus on support tools for socio-ecological sustainability integration in the early product development stages.

    Mining data to design value: a demonstrator in early design2017In: Proceedings of the International Conference on Engineering Design, ICED / [ed] Fadel G.,Salustri F.,Kim H.,Skec S.,Van der Loos M.,Maier A.M.,Kokkolaras M.,Oehmen J., The Design Society, 2017, Vol. 7, p. 21-29, article id DS87-7Conference paper (Refereed)
    Abstract [en]

    The paper presents a study run to verify the applicability of data mining algorithms as

    decision support in early design stages of a product development project. The paper

    describes a two-stage scenario providing the rationale for the application of data science in

    engineering design. Furthermore, it describes a demonstrator showing how data can be fed

    back to the early design stages and can be used to populate models to reduce uncertainty in

    decision making. A wheel loader for constructions works is the reference product for the

    demonstration. Data mining is applied on a dataset built on machine performances and

    contextual and environmental data. The demonstrator focuses on the estimation of the fuel

    consumption of alternative design concepts and estimates the performance variations given

    different contextual variable. Finally, a way of visualizing the results of the data analysis in

    relation to the tested and expected performances is presented.

    Product-Service Systems for Functional Offering of Automotive Fixtures: Using Design Automation as Enabler2017In: Procedia CIRP: 9th CIRP Conference on Industrial Product/Service-Systems (IPSS), Copenhagen, Elsevier, 2017, Vol. 64, p. 411-416Conference paper (Refereed)
    Abstract [en]

    In production of automotive components, control-measuring is an important activity to assure that geometries meet expected tolerances. This is done via randomly taking parts out of production for control-measuring in a fixture. This fixture is both a tedious and repetitive product to design and configure. The aim of this paper is therefore to present an approach to adopt a design automation strategy towards supporting the configuration of fixtures and to discuss opportunities for moving towards a Product-Service System-paradigm in this domain. This paper reports on a development of a design automation demonstrator to configure fixtures for control-measuring. The demonstrator has been developed in a commercial CAD-environment and will be deployed through a web-based interface. The paper concludes with a discussion on PSS-opportunities and how to drive this with a Knowledge-Based Engineering-modelling approach.

    Science in support of systematic leadership towards sustainability2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 140, p. 1-9Article, review/survey (Refereed)
    Abstract [en]

    The un-sustainable course of our societies is the greatest threat humanity has ever confronted. The biophysical systems upon which we are totally dependent have not been challenged by human activities at the global scale before and our impacts upon those planetary systems, as well as upon our social systems, cannot be adequately addressed by ad hoc solutions. Science and leadership will be required to address this threat and transform our current societies into sustainable societies. This Special Volume presents an evolving, yet increasingly cohesive, science-based perspective on leadership towards sustainability. Examples of crucial, overall questions addressed by authors of articles in this Special Volume are: How can science help to clarify sustainability as a foundational platform for success for society's core institutions (e.g. business, governance and education), and how can this platform inform envisioning, planning, monitoring, communication and decision making to accelerate the needed transitions? The conceptual framing of sustainable development in this Special Volume is based upon the logic that it is only if we can define sustainability in a scientifically solid way, as a frame for any vision, that we can analyze current situations in relation to such sustainable visions, and design strategies to close the gap to such visions. In moving from current situations towards possible sustainable futures, specific support in the form of leadership concepts, methods, tools, and requirements are also essential, i.e. given clarity around what needs to be achieved, effective leadership then requires knowing how to achieve it. Both the what and the how questions are addressed in this Special Volume. The research described provides a foundation for moving from ad hoc activities to systemic, systematic and strategic transitions towards sustainability. © 2016 Elsevier Ltd

    Simulation-driven design for assessing strategic decisions in the conceptual design of circular PSS business models2017In: Procedia CIRP: The 9th CIRP IPSS Conference: Circular Perspectives on Product/Service-Systems, Elsevier, 2017, Vol. 64, p. 25-30Conference paper (Refereed)
    Abstract [en]

    Due to ever increasing challenges faced by our global society, circular design and the idea of product-service systems (PSS) isgaining traction within businesses. However, ‘predicting’ the value of a future PSS solution in the early design phases is difficult,since it requires the ability to balance long term potential with short term decisions. Modelling and simulation is believed to beable to support this challenging task. A simulation framework for circular design of PSS is presented. The simulation processenables the comparison between functional and non-functional performances and their life cycle contributions depending on adefined PSS-like business model strategy. Such integrated simulation framework is intended to exploit engineering modelsoutside their specific discipline, enabling cross-functional collaboration and help decision makers understand how a design cancontribute in satisfying customer and stakeholders needs during the lifecycle of a PSS.

    Abstract [en]

    The topic of ‘design for value’ has lately attracted a great deal of attention within the engineering design community. ‘Predicting’ the value of a future solution is however difficult, especially in early design phases. Modelling and simulation is believed to be able to support this challenging task.

    A simulation process for value-driven engineering design is presented. The performances of a design concept along the lifecycle are aggregated to a monetary system value function. The results of this multi-model simulation environment for value are displayed through a colour-coded CAD model for easier interaction.

    Verification activities indicate that enabling effective design space exploration and visualization of cause-effect relationships become important elements in order to ‘think together’ using a simulation driven design approach. Furthermore, the proposed multidisciplinary ‘value model’ fosters cross-functional knowledge sharing and collective deliberation about the value, forcing stakeholders to synthetize their perceptions about the value of a design and to discuss where conclusions differ.

    Additive Manufacturing Technology Potential: A Cleaner Manufacturing Alternative2016In: INTERNATIONAL DESIGN ENGINEERING TECHNICAL CONFERENCES AND COMPUTERS AND INFORMATION IN ENGINEERING CONFERENCE, 2015, VOL 4, AMER SOC MECHANICAL ENGINEERS , 2016, Vol. 4Conference paper (Refereed)
    Abstract [en]

    This paper focuses on an emerging manufacturing technology called Additive Manufacturing (AM) and its potential to become a more efficient and cleaner manufacturing alternative. This work is built around selected case companies, where the benefit of AM compared to other more traditional technologies is studied through the comparison of resource consumption. The resource consumption is defined as raw materials and energy input. The scope of this work is the application of AM in the scale model kit industry. The method used is the life cycle inventory study, which is a subtype of life cycle assessment (LCA). The result of the paper is the quantification of raw materials and energy consumption. The outcomes shows that AM has higher efficiency in terms of materials usage, as a higher proportion of materials ending up in the final product. Injection Molding (IM), on the other hand, wastes a significant proportion of raw materials in components that are not part of the final product. If the same or similar raw materials are used in both manufacturing methods, the advantage is clearly with AM. However, AM has higher energy consumption in comparison to the injection molding technique (IM). In terms of energy consumption, AM only has an advantage in this area when working with a very low production volume. The analysis of the energy consumption shows that most of the energy used in AM is to create the final product, while IM only uses a fraction of the total energy to produce the final product. AM technologies are still very new but have the potential for development and reduction of energy consumption in the future. Added to this potential is the higher materials usage efficiency of AM, which reduce the waste of materials and the energy, embedded in them. These two factors are likely to position AM as cleaner manufacturing alternative.

    An Approach to Business Modeling for Sustainable Personal Road Transport2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Between 1950 and 2013 the total amount of Swedish travelling has increased from about 20 billion to about 140 billion passenger kilometers. This included an increase in travelling with private cars from about 3 billion to about 105 billion passenger kilometers, and in bus travelling from about 2.5 billion to about 5 billion passenger kilometers. The European commission has indicated that public transportation (if powered by clean fuels) is a suitable way to reduce environmental and health problems.

     

    This thesis focuses on sustainable personal road transport, and aims to develop and test a new approach to examining the economic and socio-ecological sustainability effects of various road vehicles for private travelling and related business models. A special focus is set on comparing various bus systems for public transport and ways (business models) for private people to access cars. The main comparison parameters are the total cost of ownership and carbon dioxide emissions of different energy carriers for buses and cars. The Design Research Methodology is used to guide the research approach. The approach also builds on the Framework for Strategic Sustainable Development, which includes, for example, principles that define any sustainable future and a strategic planning process. The approach first employs Strategic Life Cycle Assessment to give a quick overview of sustainability challenges in each bus life cycle stage from raw materials to end of life. Several analysis tools such as Life Cycle Costing, Life Cycle Analysis, Product Service System, and Business Model Canvas mapping are then iteratively used to ”dig deeper” into identified prioritized challenges. Literature reviews, interviews, and simulations are used as supporting methods.

     

    The results from a first theoretical test of the new approach suggest that a shift from diesel buses to electric buses (powered by renewable energy) could significantly lower carbon dioxide emissions, while also significantly lowering the total cost of ownership. The theoretical calculations were followed up by testing of electric buses in real operation in eight Swedish municipalities. The tests verified the theoretical results, and showed that electric buses are better than diesel buses both from a sustainability point of view and a cost point of view, and also that electric bus operation is a practically viable alternative for public transport. The new approach was tested also by comparing a variety of business models for private car travelling. The results indicate, among other things, that only people who travel more than 13.500 kilometers per year would benefit from owning a car.

     

    In all, the thesis suggests a simultaneous shift from diesel buses to electric buses in public transport and, for the majority of the car drivers that drive less than 13.500 kilometers per year, switching from car ownership to car use services would be favourable for an affordable transition of the transport sector towards sustainability.

    Boundary objects for PSS design2016In: PRODUCT-SERVICE SYSTEMS ACROSS LIFE CYCLE / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, p. 329-334Conference paper (Refereed)
    Abstract [en]

    In PSS design, hardware and service developers often have different objectives. Lacking to communicate and negotiate them across boundaries might lead to solutions unable to generate market shares and long-term profitability. This paper aims to contribute to the definition of ‘boundary objects’ that facilitate the sharing of knowledge between members of cross-functional teams engaged in PSS conceptual design activities. Empirical data are gathered from three case studies in the Swedish manufacturing industry to reveal how servitization affects early stage design decision-making, and how hardware vs. service trade-offs are negotiated and solved. The analysis of the findings points to four main trends to be considered when designing such objects in the realm of PSS. These are: an underlying model-based logic, the use of metrics based on customer value, the ability to quickly generate and assess scenarios, the use of non linear relationships to map PSS features vs. customer value.

    Evaluating Health Information Systems Using Ontologies2016In: JMIR Medical Informatics, ISSN 2291-9694, Vol. 4, no 2, article id e20Article in journal (Refereed)
    Abstract [en]

    Background: There are several frameworks that attempt to address the challenges of evaluation of health information systems by offering models, methods, and guidelines about what to evaluate, how to evaluate, and how to report the evaluation results. Model-based evaluation frameworks usually suggest universally applicable evaluation aspects but do not consider case-specific aspects. On the other hand, evaluation frameworks that are case specific, by eliciting user requirements, limit their output to the evaluation aspects suggested by the users in the early phases of system development. In addition, these case-specific approaches extract different sets of evaluation aspects from each case, making it challenging to collectively compare, unify, or aggregate the evaluation of a set of heterogeneous health information systems.

    Objectives: The aim of this paper is to find a method capable of suggesting evaluation aspects for a set of one or more health information systems—whether similar or heterogeneous—by organizing, unifying, and aggregating the quality attributes extracted from those systems and from an external evaluation framework.

    Methods: On the basis of the available literature in semantic networks and ontologies, a method (called Unified eValuation using Ontology; UVON) was developed that can organize, unify, and aggregate the quality attributes of several health information systems into a tree-style ontology structure. The method was extended to integrate its generated ontology with the evaluation aspects suggested by model-based evaluation frameworks. An approach was developed to extract evaluation aspects from the ontology that also considers evaluation case practicalities such as the maximum number of evaluation aspects to be measured or their required degree of specificity. The method was applied and tested in Future Internet Social and Technological Alignment Research (FI-STAR), a project of 7 cloud-based eHealth applications that were developed and deployed across European Union countries.

    Results: The relevance of the evaluation aspects created by the UVON method for the FI-STAR project was validated by the corresponding stakeholders of each case. These evaluation aspects were extracted from a UVON-generated ontology structure that reflects both the internally declared required quality attributes in the 7 eHealth applications of the FI-STAR project and the evaluation aspects recommended by the Model for ASsessment of Telemedicine applications (MAST) evaluation framework. The extracted evaluation aspects were used to create questionnaires (for the corresponding patients and health professionals) to evaluate each individual case and the whole of the FI-STAR project.

    Conclusions: The UVON method can provide a relevant set of evaluation aspects for a heterogeneous set of health information systems by organizing, unifying, and aggregating the quality attributes through ontological structures. Those quality attributes can be either suggested by evaluation models or elicited from the stakeholders of those systems in the form of system requirements. The method continues to be systematic, context sensitive, and relevant across a heterogeneous set of health information systems.

    Innovation Enablers and Their Importance for Innovation Teams2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The aim of this research is to develop an understanding of factors that enable innovation teams to conduct agile innovation work in an industrial context. The background and reason for this research are not only that innovation is necessary for companies that want to stay in business, but also that these companies need to increase the speed of their innovation work to stay competitive. Research has demonstrated that cross-functional (X-functional) innovation teams are fast and agile, and are therefore assumed to be suitable for these activities. Still, there is much knowledge to be gained.

    Prior research has identified factors that are seen as important from an organizational, team, and individual perspective to enable teams to work with potentially innovative outcomes. However, in cases where teams have been created with the purpose of conducting innovation work, i.e. innovation teams, problems related to e.g. performance and learning have occurred, and the innovation work has stopped shortly after conducted research projects due to the high level of complexity.

    The research question (RQ) that this thesis explores is the following: “Which innovation enablers are important for innovation teams when conducting agile innovation work in an industrial context?” Based on the RQ, two sub-questions are formulated and operationalized to answer the RQ.

    Qualitative data have been collected from five innovation teams in two phases. Two innovation teams in two small- and medium-sized enterprises (SMEs) were studied in the first phase to clarify the situation for innovation teams before innovation work is begun. In the second phase, which built on the first one, three innovation teams in a large industrial company were studied as they conducted three separate innovation projects.

    This research revealed five main findings: first, knowledge about important innovation enablers (Enablers) revealed from a literature study; second, the Innovation Team Model (ITM), demonstrating innovation teams before innovation work is begun in relation to the individuals and organization in a holistic way; third, the innovation team creation process (CIT-process), a stepwise process in how to create an innovation team; fourth, the innovation facilitator, who supports and facilitates the innovation team throughout the CIT-process and the innovation projects; and fifth, the Extended Innovation Process (EIP), an extension of the traditional innovation process by a pre-phase, i.e. a Preparation-phase, to gather and prepare the innovation teams for forthcoming work. The findings regarding the importance of the CIT-process, the EIP, and the innovation facilitator were unexpected.

    The findings formed the Innovation Team Framework (ITF), which represents all of the findings in relation to each other. The EIP is used as the basis for which the other innovation enablers are provided to the innovation teams through an innovation facilitator’s competence throughout the innovation project. The ITF is multidimensional: it could serve as a tool to describe both the simplicity and the complexity when creating an innovation team and forthcoming work and activities.

    All separate findings within this research contribute to prior research in individual ways, however, the ITF is the main scientific contribution of this study to Innovation management.

    Practitioners can use the ITF as a complement to already established methodologies for product development or similar; however one should be aware of the limited nature of the data set that served as the basis for analysis and development of the ITF.

    Further studies regarding the ITF and its detailed models and processes are suggested.

    The Adoption of Additive Manufacturing Technology in Sweden2016In: 13TH GLOBAL CONFERENCE ON SUSTAINABLE MANUFACTURING - DECOUPLING GROWTH FROM RESOURCE USE, 2016, p. 7-12Conference paper (Refereed)
    Abstract [en]

    This paper analyzes the adoption of Additive Manufacturing (AM) technologies in Sweden. The dataset consists of a recent and representative sample of Swedish AM users (companies, universities, and research institutes). The authors investigate two questions. Firstly, what are the current applications of AM in Sweden (e.g. Rapid Prototyping (RP), production)? Secondly, what are the factors that can explain the variation in AM adoption among the users? Using a regression analysis technique, the main findings are as follows. (i) There is a variation among users' choice of AM application, and the majority of users are expanding their AM applications beyond RP. (ii) There are two factors that positively affect the decision of firms to expand classical RP and also incorporate production and management. These two factors are using multiple AM technologies (as opposed to single Fused Deposition Modeling technology) and being small companies. The authors discuss the implication of these results.

    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.

    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.

    Virtual Modeling for Lifecycle Performance Assessment in aerospace design2016In: Product-Service Systems across Life Cycle / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, p. 335-340Conference paper (Refereed)
    Abstract [en]

    The aim of the paper is to present an approach for the multidisciplinary evaluation of alternative modular concepts in preliminary design with the intent of enhancing engineers’ capability to simulate alternative scenarios with different design configurations, so to derive decisions about the most valuable design concepts to further develop. The research contribution is novel in the way that it expands the Set-Based-Engineering approach by addressing the “servitization” challenge in two ways: firstly by the use of value models and sustainability models as decision making support, making possible a preliminary assessment of the value contribution and of the sustainability performances of a design concept;secondly, by the use of functional modelling modules and configurable systems elements for platform-based design, to manage the  complex relationships within and between parts of the platform throughout the lifecycle. The paper presents the main features of the approach and introduces an industrial case concerning the development of a module component for an aircraft engine in which the approach is applied for demonstration. The paper finally elaborates on the benefits and implications of the approach in the design process.

    Designing with Priorities and Thresholds for Health Care Heterogeneity: The Approach of Constructing Parametric Ontology2015Conference paper (Refereed)
    Abstract [en]

    Designing systems working in health care needs complying with the heterogeneous, overlapping, non-overlapping, competing, or even contradicting requirements expressed by the various actors of the health care complex environment, including regulatory bodies. The unification method introduced in this paper, utilized ontological struc- tures to unify heterogeneous requirements in different levels of ab- straction. Also the weighting and threshold algorithms defined upon the ontology structure allows to both prioritize the requirements and align design resources upon that priority, at the same time to enforce regulatory requirements in an easy, clear and integrated way and reject designs which cannot comply with them. Application of the method introduced in this paper is not limited to health care, but it might be applied in design for any heterogeneous environment.

    The Role of Additive Manufacturing Technology in job creation: an exploratory case study of suppliers of Additive Manufacturing in Sweden2015In: Procedia CIRP, Elsevier , 2015, Vol. 26, p. 93-98Conference paper (Refereed)
    Abstract [en]

    his paper investigates how Additive Manufacturing (AM) technologies, as a process innovation, may contribute to a job creation. Further, the various mechanisms in which AM may contribute to an increase in job creation as well as the types of jobs are analyzed. The analysis also goes beyond AM technologies and incorporates other non-technological factors which foster job creation, i.e. higher wages in BRIC countries, lower quality in BRIC countries, and a rising demand for western-made products. The analysis is based on a case study and the data collected was through interviews with three prominent actors within the AM technologies field in Sweden: technology developers, leading suppliers and users. The main findings indicate that AM (i) contributes to job creation in both the manufacturing sector and in the service sector, (ii) does not bring back mass production jobs from emerging economies such as BRIC, (iii) contributes to job creation in product development stages (e.g. rapid prototyping), and (iv) contributes to job creation in production stages of low-volume batches mainly of complex products. The findings also suggest there are barriers for full exploitation of AM in several areas, including education systems.

    A Decision Support Approach for Modeling Sustainability Consequences in an Aerospace Value Chain2014In: PROCEEDINGS OF THE ASME INTERNATIONAL DESIGN ENGINEERING TECHNICAL CONFERENCES AND COMPUTERS AND INFORMATION IN ENGINEERING CONFERENCE, 2013, VOL 4, ASME Press, 2014, Vol. 3Conference paper (Refereed)
    Abstract [en]

    Next generation jet engine technologies are typically driven by performance, value and environmental challenges, and appropriate technologies are developed in international research programs. One on-going engine component technology project at an aerospace component manufacturer aims to develop an engine with less fuel consumption. A likely consequence is higher pressure in the core engine, which leads to higher temperature. One way to handle the higher temperature is using a more advanced Ti-alloy for the product component, which will render a different sustainability profile. One weakness in current decision situations is the inability to clarify and understand the “value” and “sustainability” implications compared to e.g. performance features of concepts. Both “value” and “sustainability” include a rich set of features important for successful introduction of new products and product-service solutions to the market. The purpose with this research is to provide decision support for companies in early development phases for assessment of value and sustainability consequences over product-service system lifecycles. A workshop was held with the aerospace component manufacturer and a value chain partner focusing on material handling, to: i) get a better understanding of activities, flows and ownership related to the studied materials at the two companies, ii) to understand the companies’ perspective at new suggested scenarios with regard to these materials, and iii) define relevant scenarios to look into more in depth from asustainability and value perspective. Three different scenarios were developed with differences in ownership, responsibilities and value streams. It is therefore essential to be able to quickly assess and optimize consequences of such alternative scenarios. Based on the workshop experiences and scenarios, a modeling and simulation approach to assess sustainability and value consequences for the scenarios is proposed. The sustainability consequences are based on a sustainability life cycle assessment and a risk assessment. Key features of the proposed tool include: consideration of the time dimension, societal sustainability consequences, risk assessment, company value assessment, and cost/revenue perspectives.

    Abstract [en]

    Literature points out the need for companies to innovate continuously. Such need requires that companies develop capacities to exploit and improve current work as well as to develop and explore more radical opportunities. This paper is a case study that investigates the innovation capabilities of a multinational manufacturing company by interviewing a group that is mandate to support the development of those capabilities. The data was collected by semi-structured interviews, which were based on the categories of a framework previously developed. The findings speak about the importance of setting clear processes for continuation and implementation of ideas, adequate allocation of resources and management support. The discussion and conclusion are about the importance of the integration of efforts in different organizational levels and some of the future challenges integrating the innovation efforts into a natural way of working.

    Building a pathway for innovation: Lessons learned from developing an online platform2014Conference paper (Refereed)
    Abstract [en]

    Companies are constantly being pressured to innovate in order to stay competitive in the short run and have new offerings in the long run. One way of boosting innovation is to develop idea support systems that go beyond the traditional methods and tools. Through a qualitative study, this paper explores the lessons learned from developing an online platform for idea generation, and discusses it in terms of innovation process, climate, and capabilities. The results show that the platform itself is not enough for innovation. The structure and work processes around the platform are as important, which implies the need to design processes and procedures that allow an idea to develop, providing, focus, idea feedback and role clarity.

    Enhancing supply chain collaboration in automotive industry by value driven simulation2013Conference paper (Refereed)
    Abstract [en]

    This paper presents a computer-based approach for conceptual design that aims to enhance collaborative supply chain development in the automotive sector when dealing with product-service development or radical innovations. The focus of the research has been to design a simulation approach that will enable designers and managers to simulate and evaluate the value of different design options for the different stakeholders involved in the development process and to have insights about the implications between business model innovation and the engineered aspects of the solutions early in the conceptual phase. The approach is presented using a case study within the current project, after following a team responsible for the car cockpit. Four possible scenario have been simulated and evaluated using a commercial simulation software. The main advantage of the proposed approach is to enhance the awareness among designers and managers of the value of different design options, and allow them to explore further how business and design aspects profoundly affect each other, in order to support early decision-making in the design process.

    Abstract [en]

    Product-service systems (PSS), or value propositions, are foreseen to bring about challenges in product development. Traditionally, engineers normally manage tangible elements in relation to products, and are lacking approaches to deal with the intangibles incorporated in PSS development. The purpose of the paper is to elaborate on and propose a framework for value assessment and a simulation approach. Conceptual examples are used to discuss the proposed framework, and a contribution of the paper is that it exemplifies the reasons why intangible value have to be addressed more directly in industry in general and in PSS in particular.

    Manufacturing Renaissance: Return of manufacturing to western countries2013Conference paper (Refereed)
    Abstract [en]

    Manufacturing Renaissance, i.e. return of manufacturing to west, has been recently observed. This paper analyzes the patterns observed within each of the four main drivers behind this new phenomenon and delves more deeply into the driver that centers on the new manufacturing technologies such as Additive Manufacturing (AM) and 3D Printing. Next, this paper will make the case that the location of manufacturing will be in west, relying on the established theory that has been able to explain the location of manufacturing, i.e. Product Life Cycle Model (PLC).

    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.

    Systematic leadership towards sustainability2013In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 64Article in journal (Refereed)
    Abstract [en]

    Systematic leadership towards sustainability implies utilization of systems thinking for step-wise approaches to transformative changes towards sustainable societies. This ‘call-for-papers’ (CfPs) for a Special Volume of the Journal of Cleaner Production is focused upon what types of research are needed for us to make the necessary local, regional, national and global changes. This CfPs is for anyone who wishes to address these challenges seriously, that is, to utilize essential aspects of leadership to contribute strategically to the transition towards sustainable societies. To successfully address these challenges, people from different sectors and disciplines must work together in a coordinated and efficient way. We wish to explore the question: What support do such transformative endeavors require and how can science contribute?

    Impacts of project-overload on innovation inside organizations: Agent-based modeling2012Conference paper (Refereed)
    Abstract [en]

    Market competition and a desire to gain advantages on globalized market, drives companies towards innovation efforts. Project overload is an unpleasant phenomenon, which is happening for employees inside those organizations trying to make the most efficient use of their resources to be innovative. But what are the impacts of project overload on organization’s innovation capabilities? Advanced engineering teams (AE) inside a major heavy equipment manufacturer are suffering from project overload in their quest for innovation. In this paper, Agent-based modeling (ABM) is used to examine the current reality of the company context, and of the AE team, where the opportunities and challenges for reducing the risk of project overload and moving towards innovation were identified. Project overload is more likely to stifle innovation and creativity inside teams. On the other hand, motivation on proper challenging goals are more likely to help individual to alleviate the negative aspects of low level of project overload

    Resource Consumption in Additive Manufacturing with a PSS Approach2012Conference paper (Refereed)
    Abstract [en]

    Since the 1980’s, additive manufacturing (AM) has gradually advanced from rapid prototyping applications towards fabricating end consumer products. Many small companies may prefer accessing AM technologies through service providers offering production services as result-oriented Industrial Product-Service System (IPSS) rather than investing in their own production line. This study investigated potential benefits of IPSS using system dynamics modeling to study resource demands between two situations: one where an IPSS approach is used and one that is the traditional ownership of production equipment. This study concluded that AM service providers with demand-varying customers could increase service performance and maximize use of production equipment.

    Revisiting the Research Field of Product-Service Systems Development2012Conference paper (Refereed)
    Abstract [en]

    The research within the Product-Service Systems (PSS) field 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 industrial idea of providing customer benefits in parallel with robust products is not new, yet equipping engineers to conduct innovation and applying a service perspective in the early design stages is noticed as fairly radical. The purpose in this paper is two-fold. First, to describe research efforts within the PSS field seen through our engineering design lenses, second, to explore and discuss plausible directions and by that identify “white spots” on the map, which may be seen as relevant directions for future research.

    The rise of social product development2012In: International Journal of Networking and Virtual Organisations, ISSN 1470-9503, Vol. 11, no 2, p. 188-207Article in journal (Refereed)
    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.

    Towards Value Driven Simulation of Product-Service Systems: A Conceptual Scenario2012Conference paper (Refereed)
    Abstract [en]

    The paper discussed potentials and existing challenges of considering Value when designing a Product-Service System offering. The main problem has been identified on having new methods and tools that can help designers to consider every design option from a value perspective (possibly based on a longer timespan). Nowadays mainly revenue, costs and technical risks analysis are taken into consideration and boiled down into monetary terms in a rather short period. This often caused the “killing” of more radical ideas (that could potentially bring more benefits if seen in a longer time perspective) at the various decision gates during the project. So at the end, everybody talks about value, but actually money is what people look at in the end. The paper discussed how a Value simulation approach can provide benefits in terms of compared different design solutions from a Value perspective. With such an approach it is possible to take into consideration the value of aspects like intangibles perceived by the customer (provide the best customer experience as possible) or knowledge gained by the company during the business. An example has been presented in order to discuss how Value simulation can be effectively a strength when dealing with the wider design space that the PSS development implies. Another main benefit is that such a tool will enable engineers to have at least “reasoning” in order to sponsor more radical concepts. Thirdly, the tool can enable optimization and increase innovation, since the team can look at why the model has low value in a certain lever, and starting to brainstorm possible solutions of how to increase it. However, the approach is still in its infancy and future work needs to be done. First of all, the weighting phase is crucial since it will profoundly affect the model. Further research will focus how the design team can place define weights in a qualitative but effective way, in order to take the major benefits from a “lightweight” qualitative approach and the simulation based on mathematical equations. Secondly, work has to address how intangibles and knowledge can affect monetary parameters, such as the price of the offerings or costs (making the intangibles tangible, so to say). This will require further research, but it has been seen as a great opportunity of making a step further in the topic, since the uncovered areas realted intangibles and knowledge are still many.

    Value simulation in conceptual phases of PSS design2012Conference paper (Refereed)
    Abstract [en]

    This paper discuss the change in early design imposed by a Product-Service Systems (PSS) perspective onto the design and development phases of engineering design and how this affects the today de-facto standard of virtual modelling of product properties. The approach is exemplified via PSS situations related to aerospace and automotive industry in order to clarify “parameters of change” due to PSS reasoning, and challenges are displayed regarding early modelling and simulation.

    A case study of how knowledge based engineering tools support experience re-use2011Conference paper (Refereed)
    Abstract [en]

    A manufacturing company’s unique intellectual capital is to a large extent built on experience from its own product development and manufacturing processes. Thus, methods and tools to utilize and benefit from this experience in an efficient way have an impact on a company’s ability to stay competitive and advance on the global market. Knowledge Based Engineering (KBE) is an engineering methodology to capture engineering knowledge systematically into the design system. Hence, KBE tools are considered to support experience re-use and improve engineering activities. This paper presents the results from a study where the objective was to investigate the support for experience re-use in KBE applications in an aerospace company. A proposed framework is presented to analyze the capturing and use of experience in a company’s processes identifying gaps and propose improvements. The study revealed weaknesses in the process steps for experience feedback which can be used to improve KBE applications further.

    A knowledge-based master-model approach with application to rotating machinery design2011In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 19, no 4, p. 295-305Article in journal (Refereed)
    Abstract [en]

    Novel rotating machinery design concepts and architectures are being explored to reduce mass, energy consumption, manufacturing costs, and environmental impact while increasing performance. As component manufacturers supply parts to original equipment manufacturers, it is desirable to design the components using a systems approach so that they are optimized for system-level performance. To accomplish that, suppliers must be able to model and predict the behavior of the whole machinery. Traditional computer-aided design/computer-aided engineering master-modeling approaches enable manual changes to be propagated to linked models. Novel knowledge-based master-modeling approaches enable automated coordination of multidisciplinary analyses. In this article, we present a specific implementation of such a knowledge-based master-modeling approach that facilitates multidisciplinary design optimization of rotating machinery. The master-model (MM) approach promotes the existence of a single governing version of the product definition as well as operating scenarios. Rules, scripts, and macros link the MM to domain-specific models. A simple yet illustrative industry application is presented, where rotor-dynamics and displacement analyses are performed to evaluate relocation alternatives for the rear bearing position of a rotating machinery under a ‘fan-blade-off’ load case.

    An on-road study of head-up display: Preferred location and acceptance levels2011Conference paper (Refereed)
    Abstract [en]

    The purpose of this study was to gain a better understanding of driver's perceptions of Head-Up Displays (HUD). Many HUD studies have been conducted but few have allowed drivers to test a HUD in their own vehicle, allowing them to choose the best HUD location for themselves. Forty participants drove their own vehicles using a portable HUD device, testing different HUD locations, and then rated the HUD using the Technology Acceptance Model. The results showed that the HUD was rated as easy to use and the drivers intended to use it in continuation. The drivers wanted the HUD to be located outside of the traffic scene, below their line of sight. These results give support for new HUD locations and for increased HUD implementation.

    Assessing the Value of Sub-System Technologies including Life Cycle Alternatives - an aerospace investigation2011Conference paper (Refereed)
    Abstract [en]

    Emerging from an industrial case study in the aerospace industry, the paper proposes an approach to evaluate sub- system 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.

    Expanding the social dimension - Towards a knowledge base for product-service innovation2011Conference paper (Refereed)
    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.

    Knowledge sharing across boundaries - Web 2.0 and product-service system development2011Conference paper (Refereed)
    Abstract [en]

    In recent years there has been a growing interest among product development organizations to capitalize on engineering knowledge as their core competitive advantage for innovation. Capturing, storing, retrieval, sharing and reusing of engineering knowledge from a wide range of enterprise memory systems have become crucial activities of knowledge management practice in competitive organizations. In light of a changing and dynamic enterprise definition, including a move towards Product-Service System (PSS) development, this paper discusses some of the limitations of current enterprise systems in reusing engineering knowledge across functional and corporate boundaries. Further, the paper illustrates how Web 2.0-based collaborative technologies can leverage cross-functional knowledge for new PSS development projects through an open, bottom-up, and collective sense-making approach to knowledge management.

    Measuring innovation capability - Assessing collaborative performance in product-service system innovation2011Conference paper (Refereed)
    Abstract [en]

    This paper reports on a qualitative study, carried out at a Swedish aero engine manufacturer. The study was initiated to explore key indicators related to innovation capability in a Product-Service System (PSS) context. Developing PSS changes the dynamics of collaboration, since the offering of such systems usually involves a network of partners sharing the responsibility for a delivered function over a full lifecycle. In particular, this paper focuses on describing aspects related to external and internal collaboration, and it further discusses how to measure the company’s collaborative performance, taking into account both activity and effect measures.

    Methods and Tools for Knowledge Sharing in Product Development2011In: Innovation in Product Design: From CAD to Virtual Prototyping / [ed] Bordegoni, Monica; Rizzi, Caterina, New York: Springer , 2011, p. 37-53Chapter in book (Refereed)
    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.
