一、模糊危害度的概念 故障模式及效应分析(FMEA)的目的是将致命效应的故障模式消灭在设备(即系统)使用之前,因此,故障的危害度是FMEA中的一个重要概念。 进行危害度分析的任务是:首先将危害度大的故障模式找出来,然后采取相应措施予以消除或使其发生的概率尽可能降低。
First, the concept of fuzzy damage The purpose of the failure mode and effect analysis (FMEA) is to destroy the fatal effect of the failure mode before the equipment (that is, the system) to use, therefore, the degree of fault hazard is an important concept in FMEA. The task of analyzing the degree of danger is to find out the failure modes with high degree of danger first and then take the corresponding measures to eliminate or make the probability of occurrence as low as possible.
