探索机械智能CAD系统的可拓决策方法

研究基于可拓知识模型和决策模型的机械智能ＣＡＤ方法，它不仅能够表示和处理设计中的信息转化关系，而且能够利用物元变换理论进行复杂的辩证和求异推理，转化约束问题中的矛盾因素，从而为解决定量计算与辩证分析决策共存系统的优化设计，形成基于可拓决策的智能ＣＡＤ理论与方法。文中探索了可拓智能ＣＡＤ系统的研究内容与方法，并给出机械产品方案设计中可拓智能ＣＡＤ系统的结构模式。

Research Extension Decision of Mechanical Intelligent CAD System

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.
