Abstract

While there is an extensive literature dealing with the study of queuing systems with finite capacities, a common characteristic of all these studies is the assumption of the single class of customers (jobs). In this paper we devise a model to capture the dynamics of such a system but with the assumption that arriving jobs have different service priorities. An approximation procedure, based on decomposition, is developed for the computation of the main characteristics of the model. The approximation procedure was validated using simulation data. The approximate results seem to have an acceptable error level.
