摘　　要：对两部件串联系统在部件都修复非新,当部件故障时不能立即得到修复,且修理设备也可能发生故障的假设下,研究可靠性.通过补充变量法以及广义马尔科夫过程,得到了系统的瞬时可用度、可靠度等可靠性指标的Laplace变换表达式以及系统首次故障前的平均时间.This paper considers a two components series system. In the system, the components after repairing are not as good as new. By using the method of supplementary variable and method of generalized Markov process, the Laplace transform expression of availability and reliability of the system are derived and the MTTFF is obtained.
