Abstract
Queueing systems with interruptions serve as models for a variety of situations occurring in every day life. Usually, for each type of interruption, a separate queueing analysis is required. In this paper we present a single queueing model which can be used to analyze many such systems. The model is in the form of an approximation that is based upon several parameters, which reflect the particular queueing system under consideration. Applications to queueing systems with priorities and breakdowns are given in the paper.
