摘　　要：对两不同型部件并联可修系统进行研究.假定部件的寿命均服从指数分布,部件的修理时间均服从一般连续型分布,利用补充变量法和广义马尔可夫过程得到系统的可用度、可靠度和系统等待修理的概率等一些重要的可靠性指标.Two-different-units parallel repairable system was studied in this paper. It was assumed that the life of each unit met exponentially distribution, and the repair time of the unit met general continuous distribution. By using the supplementary variable method and the generalized Markov Process, the availability and reliability of the system could be obtained. Meanwhile, some important reliability indices like the probability that the system needs repairing could also be obtained.
