| 摘 要： | 主要针对真空系统结构复杂,在维修中大量存在不确定因素的特点,在传统的故障树分析方法的基础上引用了模糊故障树的概念。简要地阐述了模糊故障树的定义,对其与传统故障树进行了比较,并且对模糊故障树进行了分析,主要包括最小割集分析法、顶事件故障概率和底事件的概率重要度。同时通过与传统故障树的对比,结合实例说明了模糊故障树在真空系统中,尤其是复杂的真空系统中进行应用的优越性。

| Abstract: | According to a large number of uncertain factors existing in the maintenance of the complex vacuum system,the concept of fuzzy fault tree was introduced based on the traditional fault tree analysis method.The definition of fuzzy fault tree was described simply.Compared with the traditional fault tree,the fuzzy fault tree was analyzed,including the minimum cut set analysis,failure probability of top event,importance of bottom event probability.By contrasting with the traditional fault tree,the superiority of... |
