摘要
分析了智能ＣＡＤ系统中复杂产品设计过程特点和设计目标的可分解性，论述了设计子目标与子知识库间的内在联系，建立了基于元知识控制的分层框架引导的层次化知识表示与知识库模型，提出了基于概念与或树模型的智能化多级领域知识获取策略。
The process characteristics of the complex product design and the resolvability of
the design goal in intelligent CAD systems are analyzed. The immanent relationship between
the design sub-goals and the sub-knowledge bases is discussed. The model of hierarchical
knowledge representation and knowledge base is set up based on the control of
meta-knowledge and the guiding of hierarchical framework. The strategy of intelligent multi-level
domain knowledge acquisition is presented based on the model of and/or tree of concepts.
