非单调关联系统的可靠性分析是目前可靠性领域中一个比较活跃的分支。本文讨论了非单调关联故障树的定量分析方法,主要内容包括计算顶事件概率值,顶事件概率分布以及各底事件的重要度排列。我们编制了一个多功能的故障树分析程序,该程序建立在早期不交化理论基础上,用它作定量分析其结果是精确的。本文还提出了一个新的重要度分析技术。最后以硝酸冷却系统为例,演示了定量分析的过程,给出了分析的主要结果。
The reliability analysis of nonmonotonic related systems is a relatively active branch in the field of reliability. This paper discusses the quantitative analysis of nonmonotonic associated fault tree. The main contents include calculating the probability of top event, the probability distribution of top event, and the importance of bottom event. We have developed a multi-functional fault tree analysis program that builds on the early theory of disagreement and uses it to quantitatively analyze the results to be accurate. This article also presents a new importance analysis technique. Finally, taking the nitric acid cooling system as an example, the process of quantitative analysis is demonstrated and the main results of the analysis are given.
