On the discrete-time Geo/G/1 retrial queueing system with preemptive resume and Bernoulli feedback

摘要

In this paper, we consider the discrete-time Geo/G/1 retrial queue with preemptive resume and Bernoulli feedback. This model unifies the FCFS and LCFS preemptive resume disciplines.We analyze the Markov chain underlying the regarded queueing system and present some performance measures of the queueing system in steady-state. Besides, the stochastic decomposition property and the corresponding continuous-time queueing system are investigated. Finally, some numerical examples are provided to illustrate the effect of preemptive resume and feedback on some crucial performance characteristics of the system.
