CBD系统应用于产品变型设计的关键技术研究

The Fundamental Technigues of CBD System Used in Variant Design

分析了实例推理技术（ＣＢＲ）的一般过程，通过对比一般设计过程和ＣＢＲ技术，说明基于实例的设计（ＣＢＤ）系统用于产品变型设计的合理性，并研究了其中的关键技术。

Case based design(CBD)is the application of case based reasoning(CBR)to the design process.By analyzing the general process of CBR,the barriers to variant design in current CAD system,and comparing the variant design process to CBR,this paper illustrates that the CBD system is reasonable for support variant design.Finally the paper discusses the fundamental techniques of CBD system used in variant design.
