- The paper summarizes the experiences of working for a decade to promote the transition of courses toward the CDIO framework. It presents a list of lessons learned when applying the CDIO principles in master-level classes in the field of Mechanical Engineering. The paper aims to formalize operational guidelines, serving as a platform for further discussion and as a set of practical recommendations for teachers and educators initially redesigning their courses toward a more CDIO-oriented structure. The paper initially presents the rationale formoving toward CDIO and describes where and how data were collected. Further, it lists several lessons learned for teachers on (1) how to support students in maximizing their learning opportunities in a CDIO context, (2) how to manage the relationship and engagement with company partners, dealing with expectations, trust, flexibility, and visibility.

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

Assessing the value of product service systems alternatives : a conceptual framework
- 2011
-
Ingår i: Design Principles and Practices. - 1833-1874. ; 5:5, s. 655-672
-
Tidskriftsartikel (refereegranskat)abstract
- The paper proposes a conceptual framework, linking value-oriented criteria, simulation approaches and knowledge sources, to support the value-driven assessment of Product/Service Systems in the preliminary product development phase. The paper describes the peculiarities of the Multi Attribute Decision Making (MADM) problem in the PSS domain, identifying relevant categories of criteria to guide the preliminary value assessment of Product/Service Systems. Each criteria has been analyzed and linked to the appropriate simulation method, and each method has been further associated to people/roles in the Virtual Enterprise who might possess relevant knowledge to populate the models. The value assessment of an aircraft engine component has been used as case study for the definition of the value attributes. The list of generic value-related criteria, coupled with the respective simulation approaches has to be considered the main result of the paper.

Assessing the Value of Sub-System Technologies including Life Cycle Alternatives - an aerospace investigation
- 2011
-
Ingår i: Glocalized Solutions for Sustainability in Manufacturing. - : Springer. - 9783642196911 ; , s. 669-674
-
Konferensbidrag (refereegranskat)abstract
- 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.

Konferensbidrag (refereegranskat)abstract
- The paper proposes an approach to increase the decision makers’ awareness at the gate, when evaluating PSS design alternatives from a lifecycle and value oriented perspective. The paper illustrates a lightweight value visualization tool, running on top of existing CAD systems, supporting value visualization of a given part or assembly, thanks to color coding. Information from value assessment is in this way translated into visual features of the CAD 3D model. Despite the approach is still on a start-up phase, an early mock-up of the tool has been developed and applied to a real aircraft engine component, in order to verify the feasibility of the approach.

Konferensbidrag (refereegranskat)abstract
- During the 3rd CIRP IPS2 conference an approach toward communicating the value contribution of different PSS design alternatives using colour-coded CAD models was presented. Building on this work, the paper presents and discusses the results of the testing activity undertaken to verify the effectiveness of the colour-coding approach. The paper describes the setting and the findings of a series of PSS Design Experiments involving 8 design teams composed by master students in product development. Through the application of protocol analysis to the recorded design sessions, the paper compares the behavior of the design teams when using colour-coded CAD models, instead of QFD-like numerical tables, for value communication in PSS conceptual design.

Modeling ‘ilities’ in early Product-Service Systems design
- 2019

Ingår i: Procedia CiRP. - : Elsevier. ; , s. 230-235

Konferensbidrag (refereegranskat)abstract
- 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 design
- 2020
-

- 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 DESIGN
- 2019

Ingår i: Proceedings of the Design Society: International Conference on Engineering Design. - : Cambridge University Press. - 2220-4342. ; , s. 2367-2376

Konferensbidrag (refereegranskat)abstract
- 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.
