Aide à décision en conception préliminaire par l'estimation du poids de la performance environnementale

Abstract : The development of an eco-design method to create products involving environmental indicators to aid decision making at the stage of conceptual design, can be found in the present work. The proposed method is based on the definition and generation of a TRIPLET: a consistent relationship between materials, processes and forms. A taxonomy of shapes characterizes different shapes achievable by the manufacturing processes. A Description of Concept (DCT) includes some overall dimensions of the piece conceived and the finishing and material removal processes. An environmental indicator based on RECIPE database and adapted to the method to be able to evaluate the environmental impact. The aid integrates two approaches, deductive and inductive based on the experience of the designer. The DCT includes choosing a solid base that suggests, based on the functional surfaces defined in the process, a reflection towards a sketch of the piece concept. The different concepts developed are ranked from a multiple-criteria decision analysis based on the environmental indicator, a manufacturing cost, a performance index and a combination index obtained by fuzzy logic. The process is supported on a database linked to the required knowledge and the software tool "ECOTRIAL". A redesign application concludes the thesis and demonstrates the applicability of the proposed method.
