并行设计的一种知识与设计过程表示模型

A Model of Design Knowledge Representation and Design Process in Concurrent Design

并行设计的许多技术问题和智能ＣＡＤ的主要研究可课题都同设计知识表示与设计过程建模密切相关．本文分析了设计过程的特点，提出了基于设计知识表示的设计过程模型，模型包含了设计过程中的基本操作，如选择、综合与细化．最后，基于该模型，说明产品的设计过程是一个从抽象资源到最终产品的递归过程．

Many technical issue of concurrent design and theoretical problems ofICAD are related to design knowledge representation and design process. Accordingto characteristics of design process, this paper proposes a model of design processbased on design knowledge representation. The model includes the basic operatorssuch as sellecting and synthesizing and refining of resource in design process. Finally,the recursive design process from abstract conception to the end product is described.
