Discrete-Time Queueing System with Expulsions
In this paper we analyze a discrete-time queueing system in which an arriving customer can decide, with a certain probability, to go directly to the server expelling out of the system the customer that is currently in service or to join the queue in the last place. The arrivals are assumed to be geometrical and the service times are arbitrarily distributed. We present some numerical examples in order to illustrate the effect of the parameters on several performance characteristics.
