Abstract
In this paper, we consider a discrete time Geom/Geom/1 queue system with (N; n)-preemptive priority discipline and multiple synchronization working vacation. A discrete time three-dimension Markov chain (MC) of this queue system is given. By using the quasi birth and death chain and matrix-geometric solution theory, the average queue length of the two classes and the probability of a customer I being preempted are obtained. In the end, some numerical and optimization results are provided to illustrate the effect of the parameters on several performance characteristics.
