摘要
介绍了模糊可靠性分析的基本概念 ,同时给出了基于故障率为模糊数的模糊故障树可靠性的分析方法。在大型复杂的三峡五级船闸监控系统故障树分析中 ,针对实际系统无法获取足够的可靠性原始数据信息 ,探讨应用模糊数学集合理论对系统进行基于故障率为模糊数的故障计算分析 ,通过计算结果分析 ,证明该方法可以应用于五级船闸监控系统的可靠性分析 。
This paper introduces fuzzy fault-tree reliability analysis, and provides an analysis method with fault rate based on fuzzy data. In the control system of the Three Gorges five-cascaded ship lock, some equipment reliability data is difficult to be obtained. So how to apply fuzzy mathematics in reliability analysis with fault rate based on fuzzy data is discussed. Calculation results in the project of Three Gorges five cascaded ship lock show that this method is correct.
