Abstract As products are being developed over time and across organisations, the risk for unintended accumulation and mis-conception of margins allocated may occur. Accumulation of margins can result in over design, but also add risk due to under allocation. This paper describes the different terminology used in one organisation and shows the different roles margins play across the design process and in particular the how margins are a critical but often overlooked aspect of product platform design. The research was conducted in close collaboration with a truck manufacturer between 2013 and 2018. The objective was to gain understanding of the current use of margins, and associated concepts evolve along the product life cycle, across organisation and product platform representations. It was found that margins already play an important role throughout the entire design process; however, it is not recognised as a unified concept which is clearly communicated and tracked throughout the design process. Rather different stakeholders have different notions of margins and do not disclose the rationale behind adding margins or the amount that they have added. Margins also enabled designers to avoid design changes as existing components and systems can accommodate new requirements and thereby saving significant design time.

Simulation Process

Automobile, aerospace, and other industrial sectors have evolved over years on product life-cycle management (PLM) systems. Product design and simulation have been long used to support their enterprise-wide engineering activities. This paper describes, in detail, a case study and solution of a simulation process management project called performance simulation model (PSM) .We focus on several research issues, including integration of design process and simulation process, simulation data management, simulation flow management, and the architecture of PSM. A prototype for PSM that allows a unification of design process and simulation process by PDM’s engineering Bill of Material (EBOM) is presented. The prototype has been used successfully for static analysis of transmission system.

Nowadays, the environmental issue has become increasingly important and has taken a leading role in the product design process. The product sustainability pass through the use of specific software tools supporting the design phase. Their integration, to build up a platform, is a key aspect toward the implementation of an effective eco-design approach. Even if the approaches presented in literature to create an eco-design platform aim to integrate environmental aspects during the design process, a proper tools integration is not existing. To overcome these limitations, the paper presents an eco-design platform in which tools for the improvement of the product environmental characteristics are contained. The tools of the platform are used to calculate the environmental impact of a product for each product life cycle phase: manufacturing, transportation, use and End of Life. The platform is completed by a tool containing the eco-design guidelines, also specific for the industrial sector of the company, used to suggest the designers how to improve the product eco-sustainability. The end users of the platform consist of designers from the design office but also from every department relevant for the project, mainly R&D, production, purchasing department, and quality. In particular, the following roles have been considered as users: designer, product manager, environmental manager and buyer. Designers and company experts use the same workspace, made of different tools. They can detail all the product life cycle phases, quantify the product performances, modify its characteristics and verify the improvements obtained without change the traditional design process in a radical way.

Over Time

Since the introduction of the concept of the product life cycle (PLC) to the marketing literature almost 67 years ago, a plethora of literature regarding this concept has appeared in the academic as well as trade journals. In spite of an extensive body of research related to PLC, several critical questions related to the product identity and changes in the identity of product over time are completely ignored by the researchers. This study is an attempt to fill this gap in the marketing literature. After defining the concept of product identity, we provide answers to the following questions: How do products stay the same even after they change? At what point does a product become different? When we talk about a certain product and say that “it changed,” what exactly is “it”?

End User Involvement

The aim of this article is to discuss how end user involvement in all stages of a product life cycle changes the assumptions of the design process. This article is based on a literature review and three case studies – Imsdal (Ringnes/Carlsberg), Jordan and Stokke. Several examples of how consumers or users are involved in various stages of the product life cycle are presented. The product development is affected both by end users’ activity and by previous knowledge of the product. The use of the product is changing the meaning, and even the disposal of the product is affecting how the product is perceived. The product becomes part of a cultural and historical context in which the end user is actively shaping.

Optimization System

Current Computer Aided Design (CAD) technologies offer parametric design functions to allow users to easily change products’ configurations, shape and dimensions without reconstructing the entire product model. A programming tool that often comes with most CAD packages enables a designer to better control the parametric interface. However, these two functions focus on rapid production of computer models, which usually takes place after the product design is completed. The product design process, which has more significant influence on product life-cycle costs, is not fully supported. This paper proposes a systematic method in which a product design can be finalized and optimized through the interactions between 3-D solid modeling and customized cost / performance analysis. The entire optimal design process and generation of design deliverables is fully automated through interactive programming. In addition, an automatic design and optimization system for industrial silencers has been developed, which takes customers’ order from the Internet, sends the order to a CAD system, generates the optimal design, and sends back the design to the customer. The entire process takes only a few minutes. The proposition of integrating customized product life-cycle considerations with the model generation and optimization, as well as the developed silencer design system should be useful for other product designs.
