Abstract:
This paper studies the optimal control of an N-policy M/Ek/1 queueing system with server breakdowns and multiple vacations. The server is turned on when N units are accumulated in the system. The server is turned off and takes a vacation with exponential random length whenever the system is empty. If the number of units waiting in the system at any vacation completion is less than N, the server will take another vacation.
