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 …

Retrial queueing systems have been extensively studied because of their applications in
telephone systems, call centers, telecommunication networks, computer systems, and in …

Abstract top We describe main models and results of a new branch of the queueing theory,
theory of retrial queues, which is characterized by the following basic assumption: a …

This paper discusses a retrial queue with Bernoulli feedback, where the server is subjected
to starting failure. The retrial time is assumed to follow an arbitrary distribution and the …

Retrial phenomenon naturally arises in various systems such as call centers, cellular
networks and random access protocols in local area networks. This paper gives a …

An M/G/1 retrial queueing system with additional phase of service and possible preemptive
resume service discipline is considered. For an arbitrarily distributed retrial time distribution …

A class of single server vacation queues which have single arrivals and non-batch service is
considered in discrete time. It is shown that provided the interarrival, service, vacation, and …

We consider an M/G/1 retrial queue with general retrial times where the blocked customers
either with probability q join the infinite waiting room (called priority queue) or with …

A retrial queue accepting two types of positive customers and negative arrivals, mixed
priorities, unreliable server and multiple vacations is considered. In case of blocking the first …

This paper deals with a multiserver feedback retrial queueing system with finite waiting
position and constant retrial rate. This system is analyzed as a quasi-birth-and-death (QBD) …
