Time-dependent analysis of M/G/1 vacation models with exhaustive service

We analyze the time-dependent process in several M/G/1 vacation models, and explicitly obtain the Laplace transform (with respect to an arbitrary point in time) of the joint distribution of server state, queue size, and elapsed time in that state. Exhaustive-service M/G/1 systems with multiple vacations, single vacations, an exceptional service time for the first customer in each busy period, and a combination of N-policy and setup times are considered. The decomposition property in the steady-state joint distribution of the queue size and the remaining service time is demonstrated. © 1990 J.C. Baltzer A.G. Scientific Publishing Company.
