摘　　要：火灾自动报警系统运行的实质是信号流遵循相应"时序"传递的过程,传统可靠性评估方法无法考虑其时序性特点.基于GO法能够描述有实际物流的系统的时序性特点,通过对火灾自动报警系统进行分析、绘制其GO图,并分别采用概率矩阵和输出状态组合的方法,构建基于GO法与故障树法比较分析的火灾自动报警系统可靠性评估模式.将其应用于具体案例,从可靠度、割集、概率重要度等可靠性参数的角度对两种方法进行比较分析,探讨时序性对系统可靠性分析的影响.研究表明,GO法可以有效解决系统可靠性分析过程中因"时序性"造成的误差.Based on GO method can describe＂time sequence＂characteristics of practical logistics system, through the analysis of automatic fire alarm system, drawing its GO figure, the reliability assessment model of automatic fire alarm system was built using the probability matrix method and output state method. Meanwhile, GO method and fault tree method are respectively used to comparative analyze this assessment model. By applying this model to the specific case to make a comparative analysis of two methods from the reliability, cut set, the probability importance of reliability parameters, the influence of＂time sequence＂on the system reliability analysis was explored. The results showed that the GO method can effectively solve the error caused by the＂time sequence＂in the process of system reliability analysis.
