摘　　要：复杂系统发生故障时 ,往往出现两个或两个以上故障现象 ,并且故障原因与故障现象之间常存在交叉关系 ,传统的故障树分析法无法对系统多故障进行诊断。本文将模糊决策的基本原理和故障树定量分析中常用的重要度分析法相结合 ,提出了一种对多故障状态的分析方法 ,并对液化气储配站烃泵灌装系统多故障状态进行了分析 ,取得了良好的应用结果。There are two or more fault omens,and the relations between fault omens and fault reasons intersect when faults take place in complex system. But the traditional fault tree analysis(FTA)method can't analyze the multi fault system. Combining the basic theory of fuzzy decision making with the analysis method of interested degree,a method of analyzing multi fault is put forward. Applying it to multi fault state of the admeasure system with hydrocarbon pump of liquefied petroleum gas storage and admeasure station,we find the result is favorable.
