    A Reverse Engineering Role-Play to Teach Systems Engineering Methods2019Ingår i: Education Sciences, ISSN 2227-7102, Vol. 9, nr 1, artikel-id 30Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Students engaged in systems engineering education typically lack experience and understanding of the multidisciplinary complexity of systems engineering projects. Consequently, students struggle to understand the value, rationale, and usefulness of established systems engineering methods, often perceiving them as banal or trivial. The paper presents a learning activity based on a three-stage reverse engineering role-play developed to increase students’ awareness of the importance of correctly using systems engineering methods. The activity was developed and integrated in the Systems Engineering course given at Blekinge Institute of Technology. Its effectiveness was analyzed through semistructured self-reflection reports along with two editions of the course. The results showed the development of students’ understanding of how to use systems engineering methods. In particular, the students realized the need to deliver detailed and easy-to-read models to the decision makers. This result was in line with the achievement of some of the intended learning outcomes of the course.

    Data-driven design in concept development: systematic review and missed opportunities2020Ingår i: Proceedings of the Design Society: DESIGN Conference 2020 / [ed] Marjanović, D.; Štorga, M.; Škec, S.;Bojčetić, N.;Pavković, N., Cambridge University Press, 2020, Vol. 1, s. 101-110Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper presents a systematic literature review investigating definitions, uses, and application of data-driven design in the concept development process. The analysis shows a predominance of the use of text mining techniques on social media and online reviews to identify customers’ needs, not exploiting the opportunity granted by the increased accessibility of IoT in cyber-physical systems. The paper argues that such a gap limits the potential of capturing tacit customers’ needs and highlights the need to proactively plan and design for a transition toward data-driven design.

    Development of a Circularity Impact and Failure Analysis: Obsolescence and Recyclability Integration2020Ingår i: Proceedings of NordDesign 2020 / [ed] Mortensen, N.H.; Hansen, C.T. and Deininger, M., The design society , 2020Konferensbidrag (Refereegranskat)
    Abstract [en]

    The application of the Failure Mode and Effect Analysis (FMEA) has been an establishedpractice in systems engineering and engineering design for some decades. The benefit ofapplying FMEA is to raise engineers’ awareness of potential risks related to a specific designconfiguration so that corrective actions can be preventively prioritized to avoid potential failureto happen. The work presented in this paper originates from the established practices of usingFMEA and FMEA Boundary Diagrams in product development and extends the scope ofanalysis by integrating circularity considerations early on in the design process. Based on suchrationale, the paper presents the first stage of the development of an approach named CircularityImpact and Failure Analysis (CIFA) aiming to become an integral part of a design for circularitystrategy. The objective of the approach is to raise engineers‘ awareness about potentialcircularity issues in early design so that they can act accordingly to create more circularsolutions. The paper presents the first results of the prescriptive work toward the developmentof CIFA, limiting the circularity considerations to the integration of obsolescence andrecyclability considerations in the FMEA. The paper presents the logic and the rationale of theapproach and exemplifies the application of the approach to the case of a bicycle V-brake.

    Introducing value driven design in engineering education: teaching the use of value models in preliminary design2020Ingår i: International journal of technology and design education, ISSN 0957-7572, E-ISSN 1573-1804, Vol. 30, nr 3, s. 531-552Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Methods and approaches for teaching engineering disciplines are evolving to adapt to the needs of companies and society. Engineering Design is one of the areas most influenced by such changes and constantly striving to develop more effective and efficient strategies to prepare the soon-to-be engineers to face the challenges of a real working environment. This paper presents an approach used to teach the use of value models for concept trade-off in the preliminary design phase, in line with the industrial challenges highlighted by the literature on Value Driven Design. The approach is based on realistic design sessions assigning to master students a value assessment challenge. The paper describes the rationale of the approach, its set-up, and a validation activity run to compare the performances of the students with those of industrial practitioners. The results of the study show that the students taking part in the design sessions can produce results that do not statistically differ from those of industrial practitioners. Moreover, the students’ self-reflection on the achievement of the intended learning outcomes show a high satisfaction toward the achievement of the educational objectives.

    MITIGATING UNCERTAINTY IN CONCEPTUAL DESIGN USING OPERATIONAL SCENARIO SIMULATIONS: A DATA-DRIVEN EXTENSION OF THE EVOKE APPROACH2023Ingår i: Proceedings of the Design Society / [ed] Otto K., Cambridge University Press, 2023, Vol. 3, s. 2665-2674Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper presents an approach where the iterative replication of Discrete Event Simulations on future operational scenarios is used to derive data-driven design merit functions. The presented contribution proposes an extension of the EVOKE (Early Value Oriented Design Exploration with Knowledge Maturity) approach determining when and how the experience-based judgment about maximization, minimization, optimization, and avoidance functions, correlating value drivers and quantified objectives, can be substituted by data-driven mathematical functions obtained by scenarios simulations. The approach is described through a simplified case concerning the development of autonomous electric vehicles to complement the public transport system in the city of Karlskrona in Sweden. The consideration of value drivers and quantified objectives presented is meant to support a preliminary screening of potential design configurations to support the definition of high-level product and system-related functional requirements, to be run before a more detailed conceptual design analysis. © The Author(s), 2023.

    Value modelling in aerospace sub-system design: linking quantitative and qualitative assessment2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper presents a prototype of a value model where engineering design teams can play with costand value data in a semi-structured way. In particular, the value model serves to facilitatecommunication of multidimensional information during preliminary design analysis and to visualizesuch information in a unique environment. The model first automatically generates, from the output ofa computer-based simulation, a quantitative assessment of manufacturer costs and customer costsaving of a set on different configuration of the same design concept. Second, it couples to the resultsa qualitative assessment of concept risks and product and process commonalities. Third, it allows anassessment of the concept impact on customer “ilities” (maintainability, survivability, scalability,flexibility). The model has been developed in collaboration with an aerospace sub-systemmanufacturer and it ultimately aims to enable the maturation of the knowledge about cost and valueaspects among the design team since the preliminary stages of design.

    Modeling ‘ilities’ in early Product-Service Systems design2019Ingår i: Procedia CiRP / [ed] Huang, GQ; Qu, T; Thurer, M; Xu, S; Khalgui, M, Elsevier, 2019, Vol. 83, s. 230-235Konferensbidrag (Refereegranskat)
    Abstract [en]

    Product-Service Systems, like all complex systems, are vulnerable to unpredictable environmental changes that can seriously undermine their ability to continuously deliver value to customers. The long-term consequences of volatile markets, unanticipated technologies, and unpredictable changes in society must be captured, modeled and communicated to decision makers since the earliest stages of the design, so to identify sustainable PSS solutions able to deliver value for years or decades to come. The paper analyses the problem of PSS changeability from the perspective of established medium-large product manufacturers facing the transition toward result-oriented PSS offers. Building on established literature in the systems engineering field, the paper proposes the definition of the changeability criteria, also named ‘ilities’, that are relevant to consider for PSS engineers in the early stages of design. Furthermore, the paper describes a systematic framework for assessing ilities in early PSS design, elaborating on technological enablers for ilities modeling.

    PSS cost engineering: A model-based approach for concept design2020Ingår i: CIRP - Journal of Manufacturing Science and Technology, ISSN 1755-5817, E-ISSN 1878-0016, Vol. 29, nr Part: B, s. 176-190Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Manufacturing companies are increasingly moving toward delivering combinations of products and services to provide higher value to their customers. The development of such Product Service Systems (PSS) escalates in complexity when several products developed by different suppliers need to be integrated into a unique system. For first tier suppliers, it is a great challenge to model and simulate the impact of changing design variables at the micro-level on both hardware properties and governing behaviours of services over the entire life-cycle of the PSS. The paper describes a model-based approach developed to estimate the life cycle cost of a PSS hardware already at a concept design stage.  The proposed approach computes the relative cost efficiency of a set of design variants using as input the data generated by the simulations run in the Computer Aided Engineering (CAE) environment. The approach allows the exploration of the design space of a PSS given by the variation of the geometry of a Computer Aided Design (CAD) model, building on the computation of customised cost modules selected by a generic list of PSS cost dimensions. For each evaluated design case, the model produces as output a unique monetary figure of the cost expected to incur by owning or using the asset throughout the lifetime. The work has been conducted in collaboration with a tier-one aerospace component manufacturer, and the application of the model is exemplified through a case study related to the development of a turbine rear structure (TRS) for commercial jet engines. The approach is most suitable for the development of complex systems in which new products and components are integrated into a shared product platform. The results are discussed in relation to the current literature on PSS cost engineering, highlighting challenges to be addressed to increase cost estimation accuracy and increase uncertainty identification and awareness.

    SUPPORTING EARLY STAGE SET-BASED CONCURRENT ENGINEERING WITH VALUE DRIVEN DESIGN2019Ingår i: Proceedings of the Design Society: International Conference on Engineering Design, Cambridge University Press, 2019, s. 2367-2376Konferensbidrag (Refereegranskat)
    Abstract [en]

    Set-Based Concurrent Engineering is commonly adopted to drive the development of complex products and systems. However, its application requires design information about a future product that is often not mature enough in the early design stages, and that it is not encompassing a service and lifecycle- oriented perspective. There is a need for manufacturers to understand, since the early design stages, how customer value is created along the lifecycle of a product from a hardware and service perspective, and how to use such information to screen radically new technologies, trade-off promising design configurations and commit to a design concept. The paper presents an approach for the multidisciplinary value assessment of design concepts in sub-systems design, encompassing the high-level concept screening and the trade-off of different design concepts, and enabling the integration of value models results into a Set-based Concurrent Engineering process. The approach is described through its application in the case study of the development of a subsystem component for a commercial aircraft engine.

    Abstract [en]

    This paper presents a prescriptive approach toward the integration of value and sustainability models in an automated decision support environment enabled by machine learning (ML). The approach allows the concurrent multidimensional analysis of design cases complementing mechanical simulation results with value and sustainability assessment. ML allows to deal with both qualitative and quantitative data and to create surrogate models for quicker design space exploration. The approach has been developed and preliminary implemented in collaboration with a major aerospace sub-system manufacturer.

    Integration of Value and Sustainability Assessment in Design Space Exploration by Machine Learning: An Aerospace Application2020Ingår i: Design Science, E-ISSN 2053-4701, Vol. 6, artikel-id e2Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The use of decision-making models in the early stages of the development of complex products and technologies is a well-established practice in industry. Engineers rely on well-established statistical and mathematical models to explore the feasible design space and make early decisions on future design configurations. At the same time, researchers in both value-driven design and sustainable product development areas have stressed the need to expand the design space exploration by encompassing value and sustainability-related considerations. A portfolio of methods and tools for decision support regarding value and sustainability integration has been proposed in literature, but very few have seen an integration in engineering practices. This paper proposes an approach, developed and tested in collaboration with an aerospace subsystem manufacturer, featuring the integration of value-driven design and sustainable product development models in the established practices for design space exploration. The proposed approach uses early simulation results as input for value and sustainability models, automatically computing value and sustainability criteria as an integral part of the design space exploration. Machine learning is applied to deal with the different levels of granularity and maturity of information among early simulations, value models, and sustainability models, as well as for the creation of reliable surrogate models for multidimensional design analysis. The paper describes the logic and rationale of the proposed approach and its application to the case of a turbine rear structure for commercial aircraft engines. Finally, the paper discusses the challenges of the approach implementation and highlights relevant research directions across the value-driven design, sustainable product development, and machine learning research fields.

    Assessing the Value of Sub-System Technologies including Life Cycle Alternatives - an aerospace investigation2011Konferensbidrag (Refereegranskat)
    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.

    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.

    Mining data to design value: a demonstrator in early design2017Ingår i: DS87-7 PROCEEDINGS OF THE 21ST INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN (ICED 17), VOL 7: DESIGN THEORY AND RESEARCH METHODOLOGY / [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, s. 21-29, artikel-id DS87-7Konferensbidrag (Refereegranskat)
    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.

    Abstract [en]

    The paper presents a Model-Driven approach for Product-Service System (PSS) Design promoting an increased digitalization of the PSS design process based on the combination of data-driven design (DDD) activities and value-driven design (VDD) methods. The approach is the results of an 8-year long research profile named (omitted for blind review) featuring the collaboration between (omitted for blind review) and nine industrial companies, in the field of PSS Design. It combines VDD models and the supporting data-driven activities in the frame of PSS design and aligns with the product value stream and the knowledge value stream in the product innovation process as described by Kennedy et al. (2008). The paper provides a high-level overview of the approach describing the different stages and activities, and provides references to external scientific contributions for more exhaustive descriptions of the research rationale and validity. The approach is meant to ultimately drive the development and implementation of a simulation environment for cross-functional and multi-disciplinary decision making in PSS, named Model-Driven Decision Arena, describe in the concluding part of the paper.

    Virtual Modeling for Lifecycle Performance Assessment in aerospace design2016Ingår i: Product-Service Systems across Life Cycle / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, s. 335-340Konferensbidrag (Refereegranskat)
    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.

    A Framework to Address Complexity and Changeability in the Design of Circular Product-Service Systems2022Ingår i: Advances in Production Management Systems: Smart Manufacturing and Logistics Systems: Turning Ideas into Action, PT II / [ed] Kim D.Y., von Cieminski G., Romero D., Springer Science+Business Media B.V., 2022, s. 19-25Konferensbidrag (Refereegranskat)
    Abstract [en]

    The design of a circular PSS solution goes beyond the traditional perspective of circular product design encompassing multiple complexity dimensions that need to be considered and addressed in the early stages of design. The paper provides a literature-based outlook on the levels of complexity to be faced when making decisions in early PSS design by positioning the concept of changeability inherited from the systems engineering literature into the context of the design of circular PSS. The paper ultimately stresses the need to consider the changeability of PSS as a relevant dimension in the assessment of its circularity potential. It does so by proposing a framework for the design of circular PSS solutions, summarizing the main design strategies and approaches currently described in the literature to mitigate the uncertainties generated by PSS complexity.

    Digital Twins of Operational Scenarios in Mining for Design of Customized Product-Service Systems Solutions2022Ingår i: Procedia CIRP, Elsevier, 2022, s. 532-537Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper presents an approach, based on the development of digital twins, to support the transition toward electromobility and autonomy in the mining industry, by supporting the design space exploration of future operational scenarios based on different construction equipment and mining site configurations. With such an intent, the paper presents an approach combining systems and systems-of-systems simulations to run trade-off analysis based on different product-service systems (PSS) configurations. Additionally, the paper integrates the "operational context"variables in PSS design simulations to create a digital twin of a "mining operational scenario"customizable for the specific configurations of each mine. The paper exemplifies the proposed approach by contextualizing in a reference mining site describing how the multi-dimensional simulations have enabled PSS trade-off analysis and PSS sensitivity analyses, and how operational context variables are integrated into the digital twin of the operational scenario. © 2022 The Authors.

    Value-driven product service systems development: Methods and industrial application2016Ingår i: CIRP - Journal of Manufacturing Science and Technology, ISSN 1755-5817, E-ISSN 1878-0016, Vol. 15, s. 42-55Artikel i tidskrift (Refereegranskat)
    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.

    A framework for data-driven design in a product innovation process: data analysis and visualisation for model-based decision making2020Ingår i: International Journal of Product Development, ISSN 1477-9056, E-ISSN 1741-8178, Vol. 24, nr 1Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The paper presents a four-layer framework for the application ofdata-driven design in a product innovation process. The framework builds onthe Knowledge Value Stream and on the Product Value Streams of a productinnovation process and indicates how data-driven activities shall be structuredand organised in relation to the different phases of a model-based decisionprocess. Visualisation is proposed as a communication enabler at the top of theframework to overcome the comprehensibility barrier between data science andengineering design models. The framework is implemented in the case study ofa construction equipment encompassing the analysis of operational machinedata and the experimentation of suitable visualisation techniques. Ultimately, alist of challenges for the implementation of data-driven design is presented, andthe capability of the framework to support the transition toward data-drivendesign is discussed in relation to the emergence of product-service systemssolutions.

    Designing solutions with the product-service systems digital twin: What is now and what is next?2022Ingår i: Computers in industry (Print), ISSN 0166-3615, E-ISSN 1872-6194, Vol. 138, artikel-id 103629Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Digital Twins (DT) are of particular interest in the domain of Product-Service Systems (PSS), to predict hardware availability, to inform about the needed features of new solutions, and to forecast the expected performances of new configurations in operation. The aim of this paper is to shed light on the extent to which ‘twins’ are applied today across the PSS life cycle, and to spotlight the ability of DT-related case studies to capture a full value perspective vs. simply attempting to represent hardware and services in the digital realm. By means of a systematic literature review combined with a mapping study, the paper reveals how only a minimal part of the existing literature is able to demonstrate how real-time physical-to-virtual and virtual-to-physical connections can be used to improve the design of servitized solutions. The analysis shows how contributions in the topic are mostly proposing frameworks and methods, as opposed to models and tools, as well as how ‘evaluation’, ‘validation’ tasks are largely neglected. As a result, the paper proposes a specialized definition of the PSS DT, together with a set of research questions that need to be answered to empower the engineering teams with relevant DT for PSS design.

    Iterative value models generation in the engineering design process2019Ingår i: Design Science, Vol. 5, artikel-id e18Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Value models are increasingly discussed today as a means to frontload conceptual design activities in engineering design, with the final goal of reducing cost and rework associated with sub-optimal decisions made from a system perspective. However, there is no shared agreement in the research community about what a value model exactly is, how many types of value models are there, their inputoutput relationships and their usage along the engineering design process timeline. Emerging from five case studies conducted in the aerospace and in the construction equipment industry, this paper describes how to tailor the development of value models in the engineering design process. The initial descriptive study findings are summarized in the form of seven lessons learned that shall be taken into account when designing valuemodels for design decision support. From these lessons, the paper proposes a six-step framework that considers the need to update the nature and definition of value models as far as new information becomes available,moving from initial estimations based on expert judgment to detailed quantitative analysis.

    Measuring Experiential Learning: An Approach Based on Lessons Learned Mapping2020Ingår i: Education Sciences, E-ISSN 2227-7102, Vol. 10, nr 1, artikel-id 11Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Fostering ‘experiential learning’ in real-life situations is a critical task for engineering educators when creating constructively aligned learning activities. The paper proposes an approach to measure the students’ perception of learning in Conceive-Design-Implement-Operate activities conducted outside the classroom. The approach is based on the opportunity of gathering and analyzing lessons learned from the student reflection reports at the end of a team-based innovation project performed in collaboration with company partners. The approach is intended to provide a basis for the future development of innovation projects with engineering students, supporting the definition of learning outcomes that are relevant for the CDIO Syllabus 2.0, and of constructively aligned learning experiences. The paper exemplifies the approach with regards to a master course named Value Innovation and presents the findings obtained at the third and second level of the CDIO Syllabus 2.0. The results of the course implementation show how short team-based innovation projects largely contributed in developing social and communication-related skills in engineering students, going beyond the mere application of their technical skills.

    Abstract [en]

    Nowadays, it is a great challenge to understand what models shall be used to iteratively translate customer desires into terms that are meaningful for engineering design decision-making. This paper proposes a framework illustrating the iterative evolution of model-based enablers for value during conceptual system design. The framework is developed from the analysis of four case studies in the Swedish manufacturing industry. The paper discusses the learning from the cross-case study, and elaborates on how value models may complement existing Systems Engineering practices.

    Nonlinear Quality Function Deployment: an experimental analysis2017Ingår i: DS87-4 PROCEEDINGS OF THE 21ST INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN (ICED 17), VOL 4: DESIGN METHODS AND TOOLS / [ed] Maier, A; Skec, S; Kim, H; Kokkolaras, M; Oehmen, J; Fadel, G; Salustri, F; VanDerLoos, M, The Design Society, 2017, s. 99-108Konferensbidrag (Refereegranskat)
    Abstract [en]

    Quality Function Deployment (QFD) is a common model to frontload engineering design activities with, linking the characteristics of a product vs. the voice of the customer using linear relationships. This approximation is often claimed to be misleading when dealing with the design of complex engineering systems. The paper presents the results of experimental activities aimed at verifying usability and effectiveness of nonlinear functions as extension of the QFD logic. A total of 40 experiments was conducted in a given design episode, involving 139 participants, to analyse the trade-off between the benefit of introducing nonlinearity vs. effort and cost triggered by increased complexity in the modelling. The results show that nonlinear functions, while improving the granularity of the QFD mapping, keeps the method simple enough to work as ‘boundary object’ in cross-functional design teams, irrespectively from the experience of design team members. The experiments also highlight how users’ cognitive attention in the task is dependent from the format by which nonlinear merit functions are presented.

    Value Driven Design revisited: emerging modelling concepts and applicatons2019Ingår i: Proceedings of the Design Society: International Conference on Engineering Design, Cambridge University Press, 2019, s. 2407-2416Konferensbidrag (Refereegranskat)
    Abstract [en]

    Extended product warranties, leasing, and pay-per-use schemes are few examples of how manufacturing companies are shifting their focus from selling products to offering “solutions”, combining products and services to maximise customer value. The idea of optimising a system towards the best ‘value’ is both "intuitive and sensible", and processes such as Value Driven Design (VDD), have been proposed to supplement traditional engineering design methodologies. Yet, value-driven initiatives struggle to communicate their benefits and to demonstrate how value models can solve actual problems. The aim of this paper is to shed light on the evolution of the VDD toolbox, mapping research clusters, applications and case studies from the perspective of how much (and how well) recent contributions have answered the five top-level questions of the VDD research agenda published in 2012. The results of the systematic literature review reveal the emergence of innovative modelling constructs, methods, and tools that help VDD in taking a leap forward in supporting organizations and teams in achieving the long-sought objective of designing for 'value'.

    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.

    EVOKE: A Value-Driven Concept Selection Method for Early System Design2018Ingår i: Journal of Systems Science and Systems Engineering, ISSN 1004-3756, E-ISSN 1861-9576, Vol. 27, nr 1, s. 46-77Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The development of new technologically advanced products requires the contribution from a range of skills and disciplines, which are often difficult to find within a single company or organization. Requirements establishment practices in Systems Engineering (SE), while ensuring coordination of activities and tasks across the supply network, fall short when it comes to facilitate knowledge sharing and negotiation during early system design. Empirical observations show that when system-level requirements are not available or not mature enough, engineers dealing with the development of long lead-time sub-systems tend to target local optima, rather than opening up the design space. This phenomenon causes design teams to generate solutions that do not embody the best possible configuration for the overall system. The aim of this paper is to show how methodologies for value-driven design may address this issue, facilitating early stage design iterations and the resolution of early stage design trade-offs. The paper describes how such methodologies may help gathering and dispatching relevant knowledge about the ‘design intent’ of a system to the cross-functional engineering teams, so to facilitate a more concurrent process for requirement elicitation in SE. The paper also describes EVOKE (Early Value Oriented design exploration with KnowledgE maturity), a concept selection method that allows benchmarking design options at sub-system level on the base of value-related information communicated by the system integrators. The use of EVOKE is exemplified in an industrial case study related to the design of an aero-engine component. EVOKE’s ability to raise awareness on the value contribution of early stage design concepts in the SE process has been further verified with industrial practitioners in ad-hoc design episodes.

    Abstract [en]

    The concept of Decision Theatre (DT) is of great interest to leverage knowledge sharing in early stage design decision events. Yet, few contributions show how to configure a DT to support design space exploration and concept selection in cross-functional teams. This paper describes the development of a model-driven decision arena (MDDA) for aero-engine sub-system design. After presenting the descriptive study findings, it illustrates the overall logic of the MDDA environment and exemplifies its use in a case study related to the design of a turbine real structure (TRS) for commercial use.

    Towards assessing the value of aerospace components: a conceptual scenario2011Ingår i: 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, s. 226-235Konferensbidrag (Refereegranskat)
    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.

    Shaping wicked problem solvers: innovating education programs through design thinking2020Ingår i: Proceedings of NordDesign 2020 / [ed] Mortensen, N.H.; Hansen, C.T. and Deininger, M., 2020, artikel-id 131Konferensbidrag (Refereegranskat)
    Abstract [en]

    Societies across the globe are facing many unprecedented challenges; climate change, pandemics, and resource depletion, just to name a few. These societal challenges, the 2030 Sustainable Development Agenda, and companies’ demands about knowledge and skills required from future employees have put pressure on academia to develop suitable education programmes in many disciplines, including product development and mechanical engineering. In this position paper, we present our work undertaken in phase-1 of the development of a new MSc programme in the field of product development and mechanical engineering at Blekinge Institute of Technology, aimed at addressing changing societal needs and demands of the future industry. We employ a generic design thinking approach, starting from key stakeholder needs with iterative execution of needfinding, benchmarking, and ideation. In these steps, we use several data collection and generation methods such as interviews, surveys, and workshops. The main outcome of phase-1 is the overall programme structure, consisting of three main focus streams — the engineering design core, three academic specializations (Product-Service Systems Design, Data-Driven Design, and Simulation- Driven Design), and the practical application profiling. Based on our experience of developing the overall programme structure, we offer recommendations for developing new programmes in this area.

    The influence factors of the stability of tailings dam based on multi-source information fusion method2019Ingår i: Journal of Intelligent & Fuzzy Systems, ISSN 1064-1246, E-ISSN 1875-8967, Vol. 37, nr 3, s. 3365-3372Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The BP neural network algorithm is used to construct a stable slope angle prediction model for open-pit mines, which can successfully predict the ultimate slope angle of the mine. At the same time, a multi-tool combination of Surpac, Madis, and Flac3D is used to create a numerical model for stable slope angle in mines. The model is used to test the final slope angle prediction structure for stable mines. Through a comprehensive analysis of the ore deposit model technology constructed by the series of realms, the economic parameters involved in the generation of realm boundaries are known, and specific primaries are pointed out with the error requirements of each parameter analyzed in the realm of series. A concrete solution is put forward to the issue of realm gap. From the point of view of the power and responsibility parameters, the series of realm production methods are analyzed, and the rapid generation methods of the realm of open-pit mine series are pointed out.

    SUPPORTING CHANGEABILITY QUANTIFICATION IN PRODUCT-SERVICE SYSTEMS VIA CLUSTERING ALGORITHM2023Ingår i: Proceedings of the Design Society, Cambridge University Press, 2023, Vol. 3, s. 3225-3234Konferensbidrag (Refereegranskat)
    Abstract [en]

    The design of Product-Service Systems (PSS) is challenging due to the inherent complexities and the associated uncertainties. This challenge aggravates when the PSS being considered has a longer lifespan, is expected to encounter a dynamic context, and integrates many novel technologies. From systems engineering literature, one of the measures for mitigating the risks associated with the uncertainties is incorporating means in the system to change internally as a response to change externally. Such systems are referred to as value-robust systems, and their development largely relies on Tradespace exploration and synthesis. Tradespace exploration and synthesis can be challenging and a time-consuming task due to dimensionality. In this light, this paper aims to present an approach that enables the population of the Tradespace and then, supports the synthesis of such a Tradespace using a clustering algorithm for support changeability quantification in PSS. The proposed method is also implemented on a demonstrative case from the construction machinery industry.

    Data-Driven Design Automation for Product-Service Systems Design: Framework and Lessons Learned from Empirical Studies.2021Ingår i: Proceedings of the Design Society 2021, Cambridge University Press, 2021, Vol. 1, s. 841-850Konferensbidrag (Refereegranskat)
    Abstract [en]

    The digitalization era has brought about unprecedented challenges for the manufacturing industries, pushing them to deliver solutions that encompass both product and service-related dimensions, known as Product-service Systems. This paper presents a number of lessons learned in the process of integrating the analysis of operational data as decision support in engineering design based on the empirical studies from two Swedish manufacturing companies operating in the construction machinery sector. The paper highlights the need to consider a five-dimensional perspective when collecting and analyzing data, encompassing data from the product, the service, the environment, the infrastructure, and the humans involved. Finally, a conceptual framework for data-driven design automation of Product-service Systems is proposed by leveraging the use of these data, introducing the concept of a Product-Service System Configurator as an enabler of design automation. The implementation of the proposed framework on multiple case studies in different industrial contexts shall be considered as the next step of the research.

    Designing Value-Robust Product-Service Systems by Incorporating Changeability: A Reference Framework2022Ingår i: Collaborative Networks in Digitalization and Society 5.0 / [ed] Camarinha-Matos L.M., Ortiz A., Boucher X., Osório A.L., Springer Science+Business Media B.V., 2022, Vol. 662, s. 623-630Konferensbidrag (Refereegranskat)
    Abstract [en]

    When a Product-Service System (PSS) has a longer lifecycle, it is subjected to several internal and external changes along its path that may deteriorate its value. A PSS capable of delivering value despite the circumstances is called a value robust PSS, and one way of achieving value robustness is by incorporating changeability. A lot of uncertainties prevail in decision-making concerning changeability as change is a phenomenon not clearly understood in PSS design. To bridge this gap, this paper presents a reference framework to support the definition and quantification of changeability in PSS design to enable the delivery of a value robust PSS. The paper is mainly focused mainly on the realization of the concept of changeability in PSS design, crossing the boundary between rich literature in the field of PSS and Systems Engineering.

    Supporting the Transition Towards Electromobility in theConstruction and Mining Sector: Optimization Framework and demonstration on an Electrical Hauler2022Ingår i: Proceedings of the Design Society, Cambridge University Press, 2022, Vol. 2, s. 1649-1658Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper presents a framework for the integration of the system’s design variables, state variables, control strategies, and contextual variables into a design optimization problem to assist early-stage design decisions. The framework is based on a global optimizer incorporating Dynamic Programming, and its applicability is demonstrated by the conceptual design of an electrical hauler. Pareto front of optimal design solutions, in terms of time and cost, together with optimal velocity profiles and battery state-of-charge is visualized for the given mining scenario.

    Incorporating changeability for value-robust product-service systems: an integrative review2024Ingår i: Design Science, E-ISSN 2053-4701, Vol. 10, artikel-id e8Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    The ongoing servitization journey of the manufacturing industries instills a through-life perspective of value, where a combination of products and services is delivered to meet expectations. Often described as a product-service system (PSS), these systems are poised with many complexity aspects, introducing uncertainties during the design phase. Incorporating changeability is one of the known strategies to deal with such uncertainties, where the system changes in the face of uncertainty to sustain value, thereby achieving value robustness. While the theme of dealing with multiple uncertainties has been discussed since the inception of PSS, changeability is still poorly addressed. To bridge this gap, an integrative literature review is performed to outline various complexities aspects and their link to uncertainty from a PSS perspective. Also, the state-of-the-art approach to achieving value robustness is presented via changeability incorporation. Subsequently, a reference framework is proposed to guide decision-makers in changeability incorporation in PSS, especially during the early design stages.

    Leveraging Information Visualization Through Extended Reality (XR) for Incorporating Changeability in Product-Service Systems2023Ingår i: Collaborative Networks in Digitalization and Society 5.0: 24th IFIP WG 5.5 Working Conference on Virtual Enterprises, PRO-VE 2023, Valencia, Spain, September 27–29, 2023, Proceedings / [ed] Luis M. Camarinha-Matos, Xavier Boucher, Angel Ortiz, Springer Science+Business Media B.V., 2023, s. 255-268Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper outlines a vision for how XR technologies can be utilized to support PSS design decisions concerning changeability with an emphasis on perceptual limitations. An XR-enabled PSS changeability incorporation method is proposed based on the extension of the Responsive Systems Comparison method by integrating XR technologies to leverage the potential of information visualization for decision-making. The proposed method is theoretically described and applied to a demonstrative case in the construction machinery industry facing the problem of designing the next-generation autonomous and electrical vehicles for quarrying and mining. © 2023, IFIP International Federation for Information Processing.

    Data-driven value creation in Smart Product-Service System design: State-of-the-art and research directions2022Ingår i: Computers in industry (Print), ISSN 0166-3615, E-ISSN 1872-6194, Vol. 137, artikel-id 103606Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The emergence of IoT has propelled the traditionally known Product-Service System (PSS) to be characterized by smarter technologies, enabling them to collect and process data from the operational stage and facilitate communication between the customer and the provider. Commonly referred to as Smart Product-Service Systems (Smart PSS), these systems promise to create value at a personal level by collecting and effectively utilizing the operational data. However, one of the fundamental challenges is the lack of awareness as to what kind of data can be collected from the operational stage and what can be achieved from this data. This paper systematically reviews scientific literature to underline the kind of data being collected from the operational stage, the purposes being achieved from that data, and how they lead to value creation. The systematic review of 60 representative studies enabled the definition of the operational scenario that comprises 4 dimensions of data and 10 classes of data within these dimensions to generically identify what kind of data is being collected. The intend presented by various authors led to the generalization of 5 themes that target different purposes of collecting data. Further, the papers were classified with regards to functional or non-functional requirements to see how data in different approaches are leveraged for value creation. Finally, the discussion highlights the current gaps in the literature and raises several opportunities for future contributions.

    Experimenting the use of value models as boundary objects in conceptual PSS design2016Ingår i: PRODUCT-SERVICE SYSTEMS ACROSS LIFE CYCLE / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, s. 370-375Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper presents the results of experimental activities aiming at investigating the role of ‘value models’ as ‘boundary objects’ that facilitate cross-functional discussions in the PSS conceptual design phase. The experiment featured 6 separate sessions involving a total of 22 students in the final year of three different Master Programmes. In the sessions participants were asked to redesign an asphalt compactor and to use different types of design decision support for this task, namely value models vs. requirements checklists. The recordings from the experiment were analysed using protocol analysis to compare the behaviour of teams. The results confirm the hypothesis that, compared to traditional requirement checklists, value models emphasizes activities related to the clarification (1) of the problem domain and needs and (2) of the lifecycle aspects of a solution concept. Both results suggest that value models have the ability to facilitate cross-boundary discussion in the early phases of the PSS design process, and to act as boundary objects that provide a common platform for knowledge sharing within the cross-functional team.

    A role for physical prototyping in Product-Service System design: Case study in construction equipment2019Ingår i: Proceedia CIRP / [ed] George Q Huang, Ting Qu, Matthias Thürer, Suxiu Xu, Mohamed Khalgui, Elsevier, 2019, Vol. 83, s. 358-362Konferensbidrag (Refereegranskat)
    Abstract [en]

    Using a case study methodology to exploring an ambitious experimental combination of a construction equipment manufacturer’s products tailored to provide exponential increases in efficiency and reductions in CO2. The products and system represent a relevant example of new technology being the foundation upon which a functional offering IPSS can be designed. The researcher constructed a scaled down functional experiential prototype reflecting a full scale experimental all electric quarry site in under operation outside of Goteborg, Sweden. The prototype site represented the primary equipment and system functionality, to act as a boundary object around which relevant stakeholders both internal and external could share the vision of an electric autonomous future. This was confirmed via observation at an event where the scale site was used for this purpose and verified with follow up interviews to dig deeper into the impact this tangible representation could have in increasing the perceived viability of the full scale technology’s potential on display thousands of miles from the event.

    PSS DESIGN INNOVATION: PROTOTYPING IN PRACTICE2020Ingår i: Proceedings of the Design Society: DESIGN Conference, Cambridge University Press, 2020, Vol. 1, s. 1355-1364Konferensbidrag (Refereegranskat)
    Abstract [en]

     Heavy equipment manufacturers recognise an opportunity to realise customer value gains through offering new Product-Service Systems. Such transition implies a radical shift in how new systems are designed. Based on a set of interviews the paper investigates how radical PSS innovation can be enabled by the use of physical prototypes as boundary object to navigate early PSS design ambiguity. On such basis, suggestions for augmenting existing support tools are made in relation to the existing literature.

    EVALUATING PROTOTYPING SUPPORT IN EARLY TRANSFORMATIVE PSS DESIGN2021Ingår i: Proceedings of Design Society 2021, Cambridge University Press, 2021, Vol. 1, s. 1411-1420Konferensbidrag (Refereegranskat)
    Abstract [en]

    Prototypes are an established tool for rapidly increasing learning, communication and decision making rationale for design projects. The proven success has spawned a litany of approaches and methods for building and planning the efficient planning and construction of prototypes. Translating these methods into simple usable tools to assist novice designers has generated broadly applicable canvases to support prototyping across the design process. Product Service System design has similarly introduced prototyping methods and tools into the process. Presently there is a lack of support for generating early phase tangible prototypes for functional PSS design aimed at more radically innovative solutions instead of currently dominant traditional products with traditional add-on services. This work explores the viability of utilizing existing prototyping support tools in the context of early PSS design through workshops with student designers and practitioners. The data from these workshops illuminates the alignments and misalignment gaps presented as guidelines to enable better support for early PSS designers.
