Performance analysis of the discrete-time GI / Geom /1/ N queue

This paper presents an analysis of the single-server discrete-time finite-buffer queue with general interarrival and geometric service time, GI/GeomIl//N. Using the supplementary variable technique, and considering the remaining interarrival time as a supplementary variable, two variations of this model, namely the late arrival system with delayed access (LAS-DA) and early arrival system (EAS), have been examined. For both cases, steady-state distributions for outside observers as well as at random and prearrival epochs have been obtained. The waiting time analysis has also been carried out. Results for the GeomIG/1/N queue with LAS-DA have been obtained from the GIIGeomIl//N queue with EAS. We also give various performance measures. An algorithm for computing state probabilities is given in an appendix.
