摘要
本文研究N部件串联可修系统的一个新模型,该模型在经典n部件串联可修系统中引入了修理工可单重延误休假的概念,并且考虑了修理设备可能发生故障而对整个系统可靠性造成的影响。假定修理工的延误休假时间、部件的寿命和修理设备的寿命均服从指数分布,部件的修理时间、修理设备的更换时间和修理工的休假时间均服从一般连续型分布,通过使用补充变量法和广义马尔可夫过程方法得到了系统和修理设备的一些重要可靠性指标。
We deal with a new mode 1 for the N-unit series repairable system, in which the conception of a repairman with possible single delay vacation is introduced, a replaceable facility＇s impact on the system reliability is also considered. It is assumed that the life of each unit, the life of the facility and the delay vacation time of the repairman are exponentially distributed. The repair time of the unit, the replace time of the facility and the vacation time of the repairman are all distributed according to general continuous distributions. By using the supplementary variables approach and method of generalized Markov process, some important reliability indices of the system and the facility are obtained.
