摘　　要：针对柴油机案例知识获取的需求,提出了一种基于模糊数学和灰色关联分析的柴油机相似性评估方法。该方法选择了柴油机的九种特征属性作为评估的依据,根据属性分类的不同采用不同的方法进行处理,其中重点介绍了对模糊概念属性的三角模糊处理方法,并利用灰色关联分析对柴油机的整体相似性给出了评估。最后对方法进行了算例验证说明。In order to meet the needs of case-knowledge acquisition, presented an estimation method for diesel engine similarity based on fuzzy number and grey incidence analysis. In this method, nine diesel characteristics were selected as basis for estimation, then dealt with them in their different ways, among which emphasized the means to deal with fuzzy linguistic by triangular fuzzy number, and evaluated the overall diesel engine similarity by the grey incidence analysis. Finally, given a numerical example to illustrate the proposed method.
