Proposal to Control the Systems Design Process: Application to Manufactured Products

This paper presents an extension of the GRAI approach in the scope of the control of design systems of manufactured products and its validation with an industrial application. The product design is defined as the evolution of a flow of informations representing the product knowledge. It is enlightened that both the design process and the product knowledge should be simultaneously and concurrently managed. We propose a model to control the design system, based on the study of the decision sub-system. This control is determined by objectives linked on the one hand, to the product (quality, cost, delay) and, on the other hand, to the system (resources, multi-projects management, cost of activities). The industrial experimentation allows us to conclude on the pertinence of the elements of control which are proposed.
