摘要
针对器件的故障发生概率不确切因素,运用模糊故障树理论,对低压成套开关设备系统进行可靠性分析。通过三角模糊数对送水泵回路进行分析,得出送水泵回路发生故障的模糊概率。它结合了概率本身的模糊性和工程上的误差,在可靠性工程上具有广泛的应用前景。
The fuzzy fault tree theory was introduced to solve reliability analysis for the low-voltage switchgear assembly system. The fuzzy failure rate of root event was described as trigonometry fuzzy number; the fuzzy failure rate in the system of water pump circuit was calculated according to fuzzy calculation rule. It has combined the fuzzy and error on the project, it has extensive application prospects on the reliability project.
