概念设计产品功能信息模型的研究

Research on Product Function Information Models of Conceptual Design

概念设计阶段的主要活动是围绕产品功能展开的。在总结现有的功能定义和功能表示方法的基础上，提出了以ＥＸＰＲＥＳＳ语言描述的概念设计产品功能信息模型。此模型具有广泛的适用性，可支持不同设计学派的概念设计活动，为计算机辅助概念设计系统的实现提供了信息模型基础。

The main activities of conceptual design is derived from product functions. The product function information models described in EXPRESS are proposed here after surveying on the definitions and the representations of product function. These models can support the conceptual design activities of different designers and can be taken as the basis of computer aided conceptual design systems.
