Integrated design of remanufacturable products based on product profiles

The mass of products at end of life becomes a real problem for the environment. Thus, industrials are turning their attention to strategies for the management of products at the end-of-life. The remanufacturing is an end-of-life strategy that reduces the use of raw materials and saves energy while preserving the value added during the design and manufacturing processes. But, in most of the cases, remanufacturing processes must be adapted to existing products because products have not been designed to be remanufacturable. However, the process adaptations increase costs and this can lead the overall benefits obtained with the remanufacturing process to be reconsidered. The aim of our research was to propose an approach for the designers to integrate remanufacturing constraints throughout the design process; mainly in the earliest phases. The eco-methodology assists designers in two steps. They are first helped in improving the reliability of a remanufacturing end-of-life strategy for that product on the bases of the analysis of the project context. Then they are guided towards a product whose properties are adapted to remanufacturing. Our approach is built upon remanufacturable product profiles (RPP) encapsulating the knowledge on both remanufacturing contexts and remanufactured product properties. For the product profile definition, eight categories of design criteria were identified based on a survey of about 30 products successfully remanufactured. A statistical analysis was made to identify clusters of products. Then, product profiles were extracted while examining the links between internal and external criteria for each group. This methodology is supported by the tool REPRO2 (REmanufacturig with PROduct PROfiles) that we have developed, which should lead to a real integrated design of remanufacturable products. Indeed, designers assisted with this tool, made early design by product profiling. It gives specific information to improve the internal technical definition of the product under study from a remanufacturing point of view.
