Résumé

The satisfaction of customers' requirements, such as quality, sustainability and cost of products, plays an important role in the context of global and concurrent economy. Thus, the requirements which products have to meet are increasingly high and tightened. However, a product during its life-cycle passes through many stages from conceptual design to the end of life. It especially passes through manufacturing and assembly stages where geometrical deviations can be generated and accumulated. At this stage of the design various simulations are made to predict product performances. All these simulations are done using the nominal model of the product coming from the modelling of the product in a CAD environment. Thus, the deviations which are obviously influent on the performances of the product are not taken into account. The performance variation due to geometric deviations can make the product designed not to meet fully the requirements of customer and user. The important issue proposed in this paper is: "How can we supervise geometrical deviations of a product, generated during its life-cycle, from earlier conceptual design stage?". In order to find out a complete answer to this question, we propose, in this paper, a method to allow geometrical deviations modelling and integration of these deviations in performance simulations of the product.
