Une nouvelle approche pour la modélisation et la gestion des contraintes en CAO

Abstract : Expertise of CAD (computer aided design) software and AI (artificial intelligence) techniques are often associated for problems resolution in many domains. Nowadays, CAD software must give the user real assistance and be able to reason. Here, we present the most important CAD system functionalities and possible used methods. Constraint problems presentation in various domains shows that their resolution can be achieved by CAD software. We will particularly discuss problems of mechanical component design, task scheduling or space planning. First we are interested in geometric and topologic constraints management during mechanical part design and more particularly in comparison of CAD models with graph normalization. This comparison allows during design, the re-use in full or in part of existing parts or extracted parts from libraries. Two methods (one algorithmic, the other using CSP formalism) are presented and allow comparison of CAD models by graph normalization. After, we are interrested in a more particular constraint type : functional constraints. A special space planning problem is considered : integreted kitchen design. Modelling and resolution methods are presented
