摘　　要：研究了修理工可多重休假的三部件串并联可修系统,假定部件寿命服从指数分布,修理时间和修理工休假时间均服从一般连续分布,利用向量Markov过程方法、Laplace变换工具和补充变量法求出了系统的可靠性指标。The serie-parallel repairable system consisting of three-unit with multiple vacations of a repairman is studied in this paper. It is assumed that the failure time of units has exponential distribution, and the repair-time and the vacation time have general continuous distributions. The reliability indices of the system is obtained by using the method of supplement variables, the vector Markov progress method and the tool of the Laplace transform.
