Bayesian control of the number of servers in a GI/M/c queueing system

Ausín, M. Concepción; Lillo, Rosa E.; Wiper, Michael P. (Elsevier, 2007)

In this paper we consider the problem of designing a GI/M/c queueing system. Given arrival and service data, our objective is to choose the optimal number of servers so as to minimize an expected cost function which depends ...
Bayesian estimation for the M/G/1 queue using a phase-type approximation

Ausín, M. Concepción; Wiper, Michael P.; Lillo, Rosa E. (Elsevier, 2004)

This article deals with Bayesian inference and prediction for M/G/1 queueing systems. The general service time density is approximated with a class of Erlang mixtures which are phase-type distributions. Given this phase-type ...
Bayesian prediction of the transient behaviour and busy period in short and long-tailed GI/G/1 queueing systems

Ausín, M. Concepción; Wiper, Michael P.; Lillo, Rosa E. (Elsevier, 2007)

Bayesian inference for the transient behavior and duration of a busy period in a single server queueing system with general, unknown distributions for the interarrival and service times is investigated. Both the interarrival ...
