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 this work, we present a bibliography on retrial queues which updates the bibliography
published in this journal in Artalejo (1999)[7]. The bibliography is focused on the progress …

Vacation models deal with a very important class of real life congestion situations
encountered in day-to-day as well as in industrial scenario. A vacation in queueing context …

In most of the queueing models, service is considered to be complete without any
interruption. But in reality, queueing systems are subject to interruptions due to failure of …

An M/G/1 retrial queueing system with two phases of service of which the second phase is
optional and the server operating under Bernoulli vacation schedule is investigated. Further …

We consider an M/G/1 retrial queue with general retrial times. Customers may balk or
renege at particular times. The server is subject to breakdown (with repairs). While the …

A repairable queueing model with a two-phase service in succession, provided by a single
server, is investigated. Customers arrive in a single ordinary queue and after the completion …

The present investigation deals with Mx/G/1 retrial queue with unreliable server and general
retrial times. The server is subject to breakdowns and takes some setup time before starting …

In this work, we consider an M/G/1 retrial queue with batch arrivals and impatient customers.
By using the method of supplementary variables, we obtain the partial generating functions …

Batch production is a modern strategy for manufacturing, especially for products unsuitable
for continuous assembly lines. This study proposes a method for analyzing one such …
