智能CAD中的产品设计知识研究

Research on the Product Design Knowledge of Intelligent CAD

如何表达产品设计知识是智能CAD系统开发中的一个关键技术。本文从智能CAD使用者——产品设计人员和智能CAD的开发者——软件开发人员的角度,对产品设计知识的结构进行了研究,提出了一个合乎设计人员思维习惯和便于软件开发实现的知识体系结构。并以CBR技术为设计知识推理使用方法,智能CAD实现了对产品设计过程的多个设计阶段的智能支持。

How to organize and use the product design knowledge is the key technology to developin the intelligent CAD (ICAD). From the views of the product designer and the ICAD software developer. This paper has done some research work on the design knowledge. A knowledge framework is put forward, corresponding to the designers thinking mode and is easy to develop. By using CBR technology, ICAD can support different stages of design process.
