Abstract [en]

Functional Product (FP) can be viewed as a business concept which is aimed at offering a function or performance to customer on an agreed upon level of availability and cost as well as at providing incitements towards a sustainable growth. The development and operation of FP is a multidisciplinary and complex process. To support such process often advanced and creative solutions are required. Based on analysis of research conducted in the Faste Laboratory, this paper aggregates FP solutions consisting of existing methods, tools and models. Further, utilisation of FP solutions is discussed from the FP life cycle perspective.

Abstract [en]

This paper features the implementation and evaluation of a proposed approach for information capture and representation integrated into the existing design environments at two manufacturing companies. A tool has been developed that automatically derives information from the CAD system during design and provides users with the means to capture product information that has previously been documented outside of the CAD system. Product information is managed in a PLM data model and becomes, once stored, the foundation for providing tailored views of information.Feedback from the evaluation shows that the prescribed approach was preferred to the current one and that it would likely provide value to users, both authors and consumers, of product information. This approach can reduce the time required to capture the pertinent product information. However, the primary savings are likely to be indirect as a result of increased consistency, understanding, and the potential (re)use of product information.The approach and tools presented constitute another step toward providing each stakeholder with more efficient, intuitive, contextual, and purposeful support for information capture and representation in computer-aided product development.

Abstract [en]

The paper provides a further verification of the Functional Products (FP) technical lifecycle and additional details regarding its four sub-lifecycles concerning: hardware, software, service-support system and management of operation. Outlined, in a novel way, is how the four sub-lifecycles may be embodied in order to manage and keep the FP technical lifecycle running at an agreed-upon level of availability. The FP technical lifecycle is further analyzed from the viewpoint of its supporting role to the FP economic lifecycle, as well as compliance, regulatory and commercial aspects.

Abstract [en]

The paper proposes a Functional Products (FP) lifecycle viewed from economic, ecologic and societal perspectives. The overall FP lifecycle is further discussed from the viewpoint of its technical and economic lifecycles. The paper suggests that the overall FP lifecycle is governed by a sustainable win-win situation between the provider and customer sides, and thus that there needs to be a balance regarding the perceived value for both parties

Abstract [en]

Sustainability is becoming increasingly important in the development of new product and production solutions, and the eco-design movement stresses the importance of environmental considerations in all design phases and activities. One such design activity in the embodiment design phase of product development is the specification of dimensional tolerances, where designers seek to ensure high functionality at low costs. A traditional approach to this decision-making process is to minimise economic losses to the manufacturer and the consumer through a process known as tolerance optimisation. This paper presents a new approach for tolerance optimisation that considers sustainability not only in the context of economic costs but also environmental impacts, which are shown to be significantly affected by manufacturing and product quality. This new framework is formulated as a bi-objective optimisation problem to minimise economic and environmental costs, and important modelling considerations for these two types of costs are outlined and discussed. The proposed approach is explored using two example cases of design assemblies, which demonstrate the trade-offs between economic and environmental design objectives as a result of tolerances and other quality-related design decisions.

Abstract [en]

Sustainable design requires simultaneous consideration of the economic, ecological, and social consequences of design decisions. The selection of dimensional tolerances and materials are two such decisions that have impacts in all three of these areas. This article presents an optimization framework along with generalized models for considering sustainability and understanding how different aspects of sustainability may trade off with one another. A mobile phone design is used as a case study to demonstrate the strengths of the approach when varying manufacturing tolerance and material choice, and the results include three-dimensional Pareto frontiers illustrating the design tradeoffs.

Abstract [en]

Product developers choose tolerances to go along with every geometric dimension, and they typically do so based on how the tolerances influence variation in so-called “critical” dimensions of the final assembled product. A common decision-making approach is to minimize costs given some acceptable critical dimensional variation, but this strategy often conflicts with ecological sustainability objectives. This paper introduces a new approach to simultaneously considering the ecological and economic consequences of tolerances through a software tool that combines Robust Design and Tolerancing (RD&T) with Environmental Priority Strategies in product development (EPS). This allows designers to simultaneously assess the economic and ecological sustainability outcomes associated with geometry, material, and tolerance choices, and it is demonstrated through design optimization of an automotive part.

Abstract [en]

Dimensional tolerances are chosen during the product development process to balance quality requirements against manufacturing costs. Designers typically judge how much variance should be allowed while still maintaining the perception of a high quality product or brand, but this is rarely based on an understanding of how consumers perceive that variance. Additionally, ecological sustainability priorities are often chosen without knowing how they will be received by consumers. This paper presents a survey-based technique for understanding how tolerance and pricing decisions influence a product developing firm’s profits, accounting for consumer perceptions of quality and environmental friendliness. A case study of a mobile phone design is explored, including variance propagation modeling, the design and administration of an online choice-based conjoint (CBC) survey, construction of consumer demand models, and profit maximization for the markets in three different countries. The results show a slight preference for high quality products compared with stronger preferences for other product attributes like low price, and the differences among the three markets are highlighted.

Abstract [en]

In the final stages of product development, dimensional tolerances are specified by designers to ensure high functionality at low costs. A traditional approach to this decision-making process is to minimize economic losses to the manufacturer and the consumer. This paper presents a new approach for tolerance allocation optimization that considers sustainability not only from economic costs but also ecological costs. The framework is formulated as a multi-objective optimization problem and explored with a case study on the design of an automotive body panel. Results of the case study include Pareto frontiers of non-dominated optimal solutions along with a parametric study to explore the influence of material choice on the results.
