C A Repairman Multiple Vacation K/n (g) Vote On Repairable System

The classical repairable system with single repairman have been studying abundantly [1]. But the hypothesis from this system is not in accord with practical case. One cause is just only one repairman in the system. Another cause is that the repairman have not been permitted for vacation. On one side, just only one repairman cannot ensure that failed component can be repaired timely in modern production and not to ensure the system running normally. On the other side, the instance that repairmen is not in the workplace has not been taken into account. To overcome the flaw above, we introduce the rules including multiple repairmen, multiple synchronous vacation and asynchronous vacation into the k/n(G) repairable system. By using quasi birth-death process and matrix-geometric solution method, we get the steady probability that the system is in every state and the indices about probability and queueing to describe the system performance. And we get special cases about the model. At last, we give the numerical example.
