M/G/1 Vacation Queueing Systems with
Server Timeout
single-server
We consider a single-server vacation queueing system that operates in the following manner.
When the server returns from a vacation, it observes the following rule. If there is at least one
customer in the system, the server commences service and serves exhaustively before taking
another vacation. If the server finds the system empty, it waits a fixed time c. At the expiration of
this time, the server commences another vacation if no customer has arrived; otherwise, it serves
exhaustively before commencing another vacation. Analytical results are derived for the mean
waiting time in the system. The timeout scheme is shown to be a generalized scheme of which both
the single vacation and multiple vacations schemes are special cases, with c = ∞ and c = 0 , respectively.
The model is extended to the N-policy vacation queueing system.
