摘　　要：在对某型燃气轮机启动进行故障分析并建立故障树的基础上,依据工程技术人员反馈得到的模糊信息,对该型燃气轮机启动过程进行了模糊可靠性分析,计算得到了在不同置信水平发生启动失效的故障概率区间,为提高装备可靠性及改进系统可靠性设计提供了依据。On the basis of establishing the fault tree for start failure of the gas turbine, the research analyses the fuzzy reliability of the start process of the gas turbine, according to the fuzzy information fed back by the engi- neering technologist and the different confidence level, we got different failure probability interval by calculating. All these consequence will offer assistance in increasing the equipment reliability and improving the system design of reliability.
