摘　　要：零部件关键重要度指标是一种在数据相对缺乏的情况下评价装备零部件重要性的简单有效方法。在小型动力电源模糊故障树基础上构建了结构函数,并根据其结构函数建立了针对小型动力电源零部件最小割集的关键模糊重要度模型。最后运用某一工作250h的小型动力电源三角模糊故障数据对该模型进行了验证。The fuzzy importance index of unit is one of simple and effective method to evaluate important degree of unit of equipment at short of the data. This paper built structure function basing on the fuzzy fault tree of mini-type motive power, then construct a fuzzy importance degree model of minimal cut set of its unit according to its structure function. Last the authors proofed this model through the triangle fuzzy fault data of one mini-type motive power been working for 250 hours.
