摘要
本文主要是对航海雷达发射机故障进行分析。首先以雷达发射机故障为顶事件,建立了模糊故障树。然后请船舶行业的专家对基本事件发生的概率进行评估,通过三角模糊数确定了各个基本事件发生的概率。最后用VC++6.0软件做出一个可以绘制模糊故障树并且可以进行定性和定量分析的系统,系统利用状态枚举法得到顶事件发生的三角模糊概率,同时系统还得到故障树的最小割集,劲集以及各个基本事件的模糊重要度,并对一些故障提出了诊断方法。
This paper is mainly a analysis of the failure of marine radar transmitter.At first,this paper uses the failure of marine radar transmitter as the top event and builds the fuzzy fault tree.Then inviting the ship industry experts to assess the probability of occurrence of each elementary event.Then using triangular fuzzy numbers to determine the probability of occurrence of each elementary event,which is used to calculate the probability of occurrence of the top event by fuzzy operator.At last,we make a system that can draw fuzzy fault tree and can do qualitative and quantitative analysis by VC＋＋ software.The system uses the state enumeration method to get the triangle fuzzy probability of the top event.The system also get the minimal cut sets,path sets and fuzzy importance of each elementary event of the fault tree,and propose some fault diagnostic method.
