摘要
本文首先详细解释了非能动系统可靠性概念,分析各种非能动系统可靠性评价方法的特点,对比各种方法之间的区别,并指出这些可靠性评价方法共同存在的不足:没有一种方法可同时兼顾非能动系统设备可靠性与功能可靠性,不能科学地整合两者的可靠性,并且未将非能动系统整体可靠性融合进概率安全评价(PSA)模型;针对各种方法存在的不足,本文在国内外研究基础上提出研究问题与思路,而且展望了非能动系统可靠性评价方法未来的发展方向。
Firstly, this paper explains the concept of passive system detailedly, and analyze features for various reliability methods of passive system, compare their differences and point out common defect in them：there was not a method that taking count of equipment reliability and functional reliability,integrating their reliabilities into a PSA; aiming at the defect, this paper propose research problem and thought upon domestic and overseas foundation of research, and outlook the future developmental direction for reliability evaluation methods of passive system.
