GO法原理和改进的定量分析方法

ＧＯ法是以成功为导向，与故障树方法完全不同的一种全新概念的可靠性分析方法。该文研究ＧＯ法的原理及其应用，系统归纳了ＧＯ法，阐明了ＧＯ法的原理。通过对ＧＯ法的定量分析，提出了引入信号流状态累积概率，导出了新的定量计算公式，并提出了共有信号的处理方法。避免了复杂的状态组合的概率计算，从而可直接进行系统状态概率的计算，易于编程，适于工程应用。根据文章提出的方法，开发了ＧＯ程序，给出了算例。结果表明，提出的改进方法是有效的，有利于ＧＯ法的发展和应用。

GO methodology and improved quantification of system reliability

This paper provides an advanced GO method for quantification of system reliability and describes the principle and application of the GO methodology. A signal state cumulative probability is introduced and quantitative formulas have been derived. The paper gives a method which can deal with shared signal. It is unnecessary to calculate probability of complex combination of states. This method is very easy for coding and is very useful in industries. According to this new method, the GO program has been developed. The result of an example shows that this method is available and it is beneficial for developing and application of GO methodology.
