摘　　要：研究了修理工可多重休假的部件串联可修系统,每个部件有两类失效状态。假定部件寿命服从指数分布,部件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过程理论和Laplace变换的方法求出了系统的可靠性指标。In this paper, an -unit series repairable system with multiple vacations is studied and each unit has two types of failure. It is assumed that the failure time of each unit has exponential distribution, while the repair time and the vacation time have general continuous distribution. By using vector Markov process theory and Laplace transform method, the reliability indices of the system are obtained.
