摘    要:研究修理工带多重休假且有优先修理权的三部件串并联可修系统,其中假定系统只有一个修理工,部件可修复如新,部件1对其它部件有抢占优先修理权,其它两部件先坏先修,且打断的修理时间可以累积计算,运用补充变量的方法,在寿命分布为指数分布,维修分布为连续型分布的假定下,求得了系统的瞬态和稳态的可用度和可靠性指标,并给出一个特例.

关 键 词:可修系统  休假  优先权  可用度  可靠度

Abstract:This paper investigates the availability characteristics and the reliability of a repairable system of three-unit with multiple vacation and preemptive priority.Assuming that the system has only a mechanic,parts can be repairable as good as new,parts 1 has the preemptive priority to be repair,the other two parts is first bad first repair and the interrupted repair-time can be cumulatived,and assuming that the life-length of the three units has exponential distribution,the repair-time has general continuous distribution,the availability characteristics and the reliability of the system are obtained by using the method of supplement variables.A special case has been given.
Keywords:the repairable system  vacation  priority  availability  reliability
