A Study of Multiple Finite-Source Queueing Models

Abstract

In this paper, the effects of the head-of-the-line priority and the first-come-first-served service disciplines and the variability of the service-time density functions on the mean values of performance measures of multiple finite-source queueing models are studied. In these models, with a single server, the times between the service completion and the next service requirement are exponentially distributed and the service times follow exponential, hypo-exponential or hyper-exponential probability density functions. The effects are compared with the known behaviour of multiple infinite-source queueing models.
