摘要 假定构成系统的元件存在多种失效过程,各失效过程相互独立,并服从非齐次泊松分布,则同一失效过程的连续两次失效事件之间的时间间隔服从幂指数分布,利用条件概率,从系统中某一指定元件完好的概率推广到某指定m个元件完好的概率,将独立失效时系统可靠度表达式转化成包含共因信息的可靠度表达式。算例验证了该理论模型的正确性。 Assuming that the components composing the system are subject to a number of different failure processes independent from each other and conforming to a non-homogeneous Poisson distribution, the time between any two successive events in one failure process is based on the power exponent distribution. Under the statistically independent component assumption, the system reliability results from the component reliability. An example is given in the paper to compare the reliability of a system with common cause failures to that with statistically-independent components.
