Based on the careful analysis of several hundred publications, this book uniformly describes
basic methods of analysis and critical results of the theory of retrial queues. Chapters …

We consider a branch of queueing theory, retrial queueing systems, which is characterized
by the following basic assumption: a customer who cannot receive service (due to finite …

In the planning of modern cellular mobile communication systems, the impact of customer
behavior has to be carefully taken into account. Two models dealing with the call retrial …

We present a survey of retrial queues with two types of calls and present new results of
several models. We consider the M1, M2/G/1 retrial queue and its variations which are the …

In this paper, we first consider single server retrial queues with two way communication.
Ingoing calls arrive at the server according to a Poisson process. Service times of these calls …

In this paper, we start with single server Markovian retrial queues with multiple types of
outgoing calls. Incoming calls arrive at system according to a Poisson process. Service times …

We consider in this paper retrial queue with one server that serves a finite number of
customers, each one producing a Poisson flow of incoming calls. In addition, after some …

A novel approximate technique is proposed for the estimation of call blocking probabilities in
cellular mobile telephony networks where call blocking triggers customer retrials. The …

In this paper, we consider a single-server retrial model with multiple classes of customers.
Arrival of customers follow independent Poisson rule. A new customer, facing a busy server …

This article deals with the steady-state behaviour of a finite orbit capacity multiserver call
center retrial queue with Bernoulli vacation schedule in which the servers not only accept …
