摘　　要：基于实例库推理的快速成本估算方法,以企业已有产品订单成本估算实例库为基础,通过检索产品或零部件配置特征,运用类比推理,为新产品订单搜寻相似产品或零部件,并以相似产品或零部件的加工过程、资源需求和成本间相互关系作为新订单成本估算准则。该方法包括实例库的组织、实例索引、实例初始化、实例搜寻和检索、实例改编五个方面的内容,通过有效地实施基于实例库推理的基本活动,能快速响应顾客关于产品价格、功能、性能和配置等方面的需求,提高企业竞争优势。Through indexing characteristics of product or components, the method of evaluating cost by Case-Base Reasoning (CBR) was applied to find out the similar product or components for configuration of new product orders. At the same time, the cost project of new orders was formed by approximately evaluating the cost of manufacturing, cost of requirement of resource and other cost. The content of CBR included of organizing Case Bank, indexing Case, initializing Case, seeking and searching Case, adapting Case. By implementing basic functions of CBR effectively, this method could quickly respond to demands of customer on price, function, performance and so on. So enterprise could raise competitive ability in market.
