Abstract

In this paper, we consider the discrete-time queueing system with bulk arrivals, generally distributed inter-batch times, geometrically distributed service times, and infinite number of servers: the GIX/Geom/∞ queue. Under the assumptions of early arrival system (EAS) and late arrival system (LAS), we derive the system size distributions at two different epochs--prearrival and random. In addition, simple relations among the binomial moments of the steady-state system-size distributions of the two systems are derived. Special cases, such as the GIX/Geom/∞ or GI/D/∞ queues, are also presented. Some numerical results are included at the end.
