摘　　要：考虑一种新型的可靠性系统 ,即修理工带有多重休假规则的单部件可修系统 ,系统发生故障时可能因修理工的休假而得不到立即修理 ,因此系统可处于工作、等待修理和修理三种状态 .在适当的假设条件下 ,讨论了系统的瞬时可用度和稳态可用度 ,以及 ( 0 ,t]时间中系统的平均故障次数和稳态故障频度 ,得到一些重要的可靠性结果 .This paper considers a one unit repairable system with multiple repairman vacations. If the system fails the repair starts immediately unless the repairman is in vacation time, in which case a waiting repairable time is needed. So that the system may be in one of three states: the working state, the waiting repair state and the being repaired state. Under the assumptions, the following reliability problems are discussed: 1) The point-wise availability and the stead-state availability ; 2) The expected failure number during a given $(0, t]$ and the stead-state failure frequency. Some important reliability results are obtained.=$ and the stead-state failure frequency. Some important reliability results are obtained.=
