Research Extension Decision of Mechanical Intelligent CAD System
探索机械智能CAD系统的可拓决策方法

In this paper, the extension decision is applied to research the knowledge representation, decision models and realization in the intelligent CAD(ICAD) . It is applied to solve the problems about deep knowledge representation and complex inference on the mechanical scheme design. The typical extension intelligent CAD system of mechanical scheme design is discussed. The extension ICAD model on the mechanical scheme design is built.
