摘　　要：以柴油机的匹配选型为应用背景,研究并开发了一个基于案例推理的柴油机辅助匹配选型系统原型,以实现对柴油机的匹配选型。系统依据柴油机的用途和主要特征属性将柴油机进行分类,根据层次分析(AHP)法确定各特征项的权重,进而根据最近邻算法对某一种类的案例集进行检索排序,最后构建了软件原型系统。通过对柴油机匹配选型案例进行仿真测试,表明了设计思想是合理的,实现方法是有效的。For developing the matching and selection of diesel engine system,this paper proposed a prototype system to solve the problem encountered in intelligent matching and selection of diesel engine on the basis of CBR（case-based reasoning）.The diesel engines are classified according to application and characteristic,the weight of each feature is determined according to the AHP method.Then,all cases were retrieved and sort by similarity with k-nearest algorithm.At last,the prototype is established.The emulation test to the software of matching and selection of the diesel engine proves that the design is reasonable and valid and effective.
