摘要
研究具有一个维修工的可修系统,且这个维修工有多个兼职工作.如果系统失效并且维修工在做兼职工作,则该系统将等待维修直到这个维修工可用,当这个维修工可用时,本系统具有优先权.维修后,本系统不能修复如新.在这些假设下,建立模型,利用几何过程和补充变量法,推导了一些重要的可靠性指标,包括可靠度、可用度、失效发生率等.最后,通过数值算例验证得到的结果.
In this paper,a repairable system with a repairman who has multiple jobs was studied.If the system fails and the repairman is working,it will wait for repairing until the repairman is available.When the repairman is available,the system has priority.After repairing,the system is not＂as good as new＂.Under these assumptions,using the supplementary variable method and the geometric process,some important indexes were derived,such as the system reliability,availability,rate of occurrence of failures,etc.Finally,a numerical example was given to illustrate our results.
