基于知识工程的CAD技术研究

CAD Techniques Based on Knowledge Engineering

产品开发过程是一种知识密集型的活动,许多研究致力于将知识工程引入CAD系统。智能CAD技术,运用知识库系统,解决了产品设计中对知识的需求的问题;基于知识的设计,实现CAD和知识工程的结合;基于配置的设计以配置器为核心技术,有效解决复杂推理问题;基于定制的设计,满足客户个性化需求的敏捷产品设计;基于设计仓库的设计,实现产品知识管理和案例管理;基于知识网络的设计,利用XML技术,为企业知识在Internet上交流提供基础。

Process of product development is a kind of knowledge-intensive activity. Many researches focus on introducing knowledge engineering to CAD system. Intelligent CAD technology, using knowledge base system, solves the knowledge requirement problems of product design. Design based on knowledge implements the integration of CAD and knowledge engineering. Configuration design solves effectively the problem of complex reasoning. Design for customization satisfies the consumer individual needs. Design based on repository realizes product knowledge management and case management. Using XML technique, design based on knowledge network provides an enterprise for knowledge sharing on internet.
