摘　　要：为实现计算机支持下产品的快速响应设计,提高产品开发效率,开发出了一种性能传导知识挖掘配置设计系统。该系统主要分为产品需求实例管理、产品配置设计过程管理、产品配置设计知识管理、产品配置方案管理4个功能模块,通过将客户的模糊性能需求转化为需求信息物元,在实例库中进行相似实例检索,构建关联函数,对检索到的不满足要求的最相似实例进行了拓展分析和可拓变换,消除了目标实例和条件实例之间的矛盾。通过设定阈值提取传导特征和传导对象,比较了相似实例变换前后性能特征数据获取主动变换对于传导特征的影响程度,通过可拓分类获取了传导变换引起的质变、量变知识。最后,以大型螺杆空压机为例,验证了该系统的有效性。研究结果表明,通过挖掘配置设计过程中的传导知识,对于提高产品配置准确性和产品开发效率有重要意义。In order to achieve rapid response design of the products supported by the computer and improve efficiency of product develop- ment, a product configuration design system of conductive knowledge miming driven by performance was developed. The system contains product requirement management module, product configuration design process management module, product configuration design knowledge management module and evaluation for product configuration management module. Customers＇ fuzzy requirements for performance were trans- formed to matter-element of information about requirements, the most similar case was retrieved in the case base. correlation function was es- tablished to analysis if the most similar case meets requirements, if not, it needs to extensive analysis and extensive transformation to resolve conflict between the target case and condition case. Conductive characteristic and conductive objects was gained by defining threshold, the impact of active transformation to conductive characteristics was gotten through comparing data about performance characteristic before and af- ter transformation, and the quality change and quantity change caused by conductive transformation was also gotten by extension classifica- tion. Finally, a large screw air compressor was used as the example to validate the system. The results indicate that it is meaningful for improving accuracy of product performance and efficiency of product development through mining conductive knowledge.
