模糊DEMATEL算法在安全性分析中的应用
|
摘要
考虑到在传统安全性分析方法中存在难以用准确数据描述系统的失效状态、确定失效模式优先级的问题,提出了将决策试验与评估实验室法(DEMATEL)和模糊集理论相结合的模糊DEMATEL算法,并将其应用到故障模式和影响分析法(FMEA)中。由专家对故障模式进行评价,借以模糊数的形式表示出来,计算得到各故障原因的原因度,确定影响因素。以民机货舱的动力驱动单元(PDU)为例进行了应用,通过改进的FMEA对故障树分析法(FTA)的分析结论进行验证,结果表明该方法有效地提高了安全性分析的可靠性和经济性,同时具有一定的通用性,为各工程领域的安全性分析提供了有力参考。
It is difficult to describe the failure state of the system and determine the priority of the failure mode with accurate data in the traditional safety analysis. In this article,DEMATEL and fuzzy DEMATEL,combined with the fuzzy set theory,are presented,and they are applied in FMEA. FMEA experts evaluate the fault mode and demonstrate the results in fuzzy numbers,and thus reasoning is calculated,so as to identify influential factors. With Power Drive Unit(PDU) in cargo-hold as an example,the improved FMEA is adopted to verify the FTA analytical results. The results show that the method significantly improves the reliability and economy of safety analysis,and can be adopted in many fields,which provides strong support for safety analysis of many engineering-related tasks.
