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 ...
