Abstract:

This paper considers the M/G/1 repairable queueing system with delay Min(N, D)-policy, in which the repair facility subject to breakdowns and then replaced during the repair facility busy period. By using the total probability decomposition technique and employing the Laplace transform tool, some reliability indices of the service station and the repair facility, such as the transient-state and steady-state unavailability, the expected failure number during (0, t] are discussed. Finally, it is determined the optimal control policy (N*, D*) such that the long-run expected cost rate is minimum under a given cost structure.

Key words: Repair facility, Delay Min(N, D)-policy, Queueing index, Reliability index, Optimal control policy
