【Abstract】 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.=更多还原
