摘　　要：针对智能CAD的实用化,分析了传统CAD方法面临的重复设计问题以及智能CAD系统的实现难点。提出了具有复合类型参数、支持有序嵌套规则并同时具备过程式描述能力的解释型知识语言设计方法。为配合知识驱动和与CAD平台的集成,提出了动作执行器,并把系统核心转移到知识语言解释器中。分析了人工知识获取和机器学习两种方式并分别提出了可行的实现思路。在此基础上设计了一个完整的智能CAD系统,在与某研究所的合作项目中得到应用并有良好效果。The repetitive design problem that traditional CAD faced and the difficulties of intelligent CAD system realization are analyzed. An interpretive knowledge representation language and its design method are presented. The language with compound types of parameters includes sequential and nesting rules, and processes process mode description capability. An operation actuator is designed having knowledge driven technology and integrating with any CAD platform, making the language interpreter becoming the system kernel. Artificial knowledge acquisition and machine learning are analyzed with the feasible solutions presented. An intelligent CAD system is realized in a research institute with the good effects.
