To achieve this, in spite of the increasing complexity of mechanical systems, it becomes necessary, amongst other things, to reduce design time. Faced with new challenges, practices in design training must evolve to allow students to be mindful of these evolutions as well as to be able to manage projects in these new work environments. After presenting a state of the art of collaborative tools used in product design, our paper presents an experiment focusing on the reverse engineering of a complex mechanical product. This experiment was carried out between two centers of the Arts et Métiers ParisTech School of Engineering, located in Paris and Angers.Weanalyze the results obtained in this experiment and propose a collaborative environment that is well suited to our needs for design education, based on ‘‘Product Lifecycle Managament’’ (PLM) concepts. Finally, we present some modifications in collaborative design courses for our students, and we implement network modifications in order to significantly improve the ease of use of the design environment.

Faced with new challenges, engineering practices have evolved to allow stakeholders to be able to manage projects in new work environments, especially during the early stages of design. After presenting a state of the art of early design tools used in product design and their integration in PLM context, we compare class diagrams for two of them : TDC software (Knowllence©) and RFLP module of CATIA V6 (Dassault Systems©). Then, our paper presents an experiment focusing on these tools, which aims to assess their usability, to evaluate and compare them. Users can raise issues, take note of which functionalities are appreciated, and provide qualitative feedback. We analyze the results obtained in this experiment and propose a comparison based on four topics: learnability, satisfaction of users, efficiency and error correction. Finally, we present some links between class diagrams and usability of the tools.

Faced with new challenges, practices in textile design have evolved in order to be able to manage projects in new work environments. After presenting a state of the art overview of collaborative tools used in product design and making functional comparison between PLM solutions, our paper proposes a case study for the development and testing of a collaborative platform in the textile industry, focusing on the definition of early stages of design needs. The scientific contributions presented in this paper are a state of the art of current PLM solutions and their application in the field of textile design; and a case study where we will present, define, and test the mock-up of a collaborative tool to assist the early stages, based on identified intermediary representations.

SMEs are particularly plagued with a lack in human, financial and time resources to integrate such aspects to design. In this paper, we propose a gradual approach (short-, medium- and long-term) to implement an eco-design process in SMEs. This process comprises four stages: analysis, sensitisation, eco-design strategy and sustained improvement. A first experimentation, in collaboration with a SME (MulTiroir-Controlec), allowed us to integrate this eco-design process in the development of a new product range of hospital carts. We present the results of the product development as well as an experience feedback on the project; today the company integrates this eco-design approach in its strategy.

The integration of people relies on the harmonisation of domain-specific glossaries by standardising a universal PLM vocabulary. So far, unfortunately, there is no PLM standard vocabulary. Therefore, the tremendous amount of knowledge that is continually brought forward by academic research studies, industrial practices and computer-aided applications causes semantic ambiguities. This paper consists of an illustrated glossary and a conceptual map. The glossary identifies, discusses, clarifies and illustrates ambiguous terms used in discrete manufacturing. The conceptual map finally underlines the logical flow of refereed definitions.

We consider the tremendous volume of requirements as big data with which companies struggle to make strategic decisions early on. This paper proposes a collaborative requirement mining framework to enable the decision-makers of an Original Equipment Manufacturer (OEM) to gain insight and discover opportunities in a massive set of requirements so as to make early effective strategic decisions. The framework supports OEMs willing to uncover a subset of key requirements by distilling large unstructured and semistructured specifications.

GAILLARD, Stéphane; MARANZANA, Nicolas; MANTELET, Fabrice; SEGONDS, Frederic Companies are faced with increasing challenges in their own environment. In several areas of the industry, but also among the suppliers, more and more competitors emerge. Companies react to this pressure by trying to implement new technologies for their products and offering more innovative products to successfully face direct competition. Overall, globalisation put pressure on companies in terms of innovation, costs and time to market. This climate of economic competition forces businesses to adapt to the expectations of their customers. To achieve this change, it becomes necessary amongst other things to reduce design time. Thus, practices in apparel design have evolved in order to be able to manage projects in new work environments. After presenting a literature review of collaborative functionalities used in product design, our paper presentsan illustration of a case study for Product Lifecycle Management research in the apparel industry, focusing on the definition of needs in terms of collaborative functions to support the design of apparel products, in an industrial context.

Architectural rehabilitation is an exceedingly complex design process, in particular, because of a legal framework which strongly impacts on the structure of collaboration, and of the need to take into account the characteristics of existing buildings. In this paper, we describe a participatory design methodology applied in the rehabilitation of a School of Engineering in France in order to improve its accessibility, and describe the basic functionalities of a software tool to assist collaborative engineering in architectural redesign projects.
