Abstract

This paper presents an approach for reliability analysis of repairable systems with two-unit parallel structure considering Common Cause Failure (CCF) and maintenance correlation based on GO methodology. First, the GO algorithm for dealing with CCF is introduced. Then, the common cause failure probability formulas of two-unit parallel structure considering maintenance correlation are deduced based on Markov theory. Furthermore, the analysis process of the new GO method is formulated. Finally, the dynamic availability analysis of HTOSS is conducted by the GO method. And the result is compared with the result of system considering CCF, and the result of system without considering CCF and maintenance correlation. The results show that the CCF and maintenance correlation are not ignored for reliability analysis of such system. All in all, this study not only widens the application of GO method. But it also provides guidance and an approach for reliability analysis of repairable systems with two-unit parallel structure considering CCF and maintenance correlation.

考虑共因故障的液压传动供油系统可靠性分析和面向成功的维修相关性分析

本文提出了一种基于GO方法的考虑共因故障和维修相关性的双单元并联可修系统可靠性分析方法。首先，介绍了处理CCF的GO算法。然后，基于马尔可夫理论推导了考虑维修相关性的两单元并联结构共因失效概率公式。在此基础上，阐述了新氧化石墨烯法的分析过程。最后，采用GO方法对HTOSS进行了动态可用性分析。并将结果与考虑CCF的系统的结果和不考虑CCF的系统的结果与维护相关性进行了比较。结果表明，在系统可靠性分析中，CCF和维修相关性是不可忽略的。总而言之，本研究不仅拓宽了GO方法的应用范围。同时也为考虑CCF和维修相关性的双机组并联可修系统可靠性分析提供了指导和方法。
