摘要
ＧＯ法与故障树（ＦＴＡ）是两种不同的系统可靠性分析方法，二者在建模的方法上存在明显差异⒀通过实例对ＧＯ法和ＦＴＡ的建模进行了比较，分析了二者之间的异同点，并进一步说明了两种方法各自的使用范围和优缺点⒀ＧＯ法是以成功状态为导向， 从系统能够正常运行或信号流能正常通过的状态中得到系统的模型； 而ＦＴＡ正相反， 它是以故障状态为导向， 在系统故障状态下逐级查找造成系统故障的原因，从而得到系统的模型⒀与ＦＴＡ相比，ＧＯ法具有模型结构紧凑，易于修改、核实等优点， 同时对于分析多状态。
GO Methodology and Fault Tree Analyze (FTA) are two different methods of the system reliability analysis. And model developments of these two methods are different. There makes a comparison study for the model developments of the GO and Fault Tree method by a case in the paper. GO Methodology is an orient success method. It uses a system flow chart approach to system modeling. This approach is in sharp contrast to the fault tree approach, which requires that the possible ways that the system may fail be identified. So the GO models are compact and easy to validate; and it has advantages in some special systems, especially in multi state, time sequence and flowing systems.
