Conception Inversée Intégrée : prédimensionnement de produits par satisfaction de contraintesInverted Integrated Design: constraint satisfaction for design support system

Mechanical design is based on aims of schedule of conditions. Design is an inverted integrated process: designers use aims to do design choices. This process, which requires a translation of all objectives, allows the synthesis of ideal dimensions (choices of materials, dimensions and shapes) from explicit and implicit rules. Rules translate all process laws and mechanical laws: mechanical calculus is integrated in design. Inverted Integrated Design (IID) process is modelized from a constraint based representation and a qualitative valuation. Constraints are analytical or are build from neural networks. Consistency techniques are used in CSPs to seek all consistent dimensions. We apply our work to the design of some pressure apparatus.
