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 …

Abstract Analysis of an unreliable-server retrial queue with customer's feedback and
impatience is presented. Truncated classical and constant retrial policies are taken into …

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 …

The main aim of this paper is to study the steady state behavior of an M/G/1-type retrial
queue in which there are two flows of arrivals namely ingoing calls made by regular …

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 …

A Markovian single server feedback retrial queue with linear retrial rate and collisions of
customers is studied. Using generating function technique, the joint distribution of the server …

This paper studies a Markov model of a queuing-inventory system with primary, retrial, and
feedback customers. Primary customers form a Poisson flow, and if an inventory level is …

We are concerned with the main multiserver retrial queue of M/M/c type with exponential
repeated attempts. It is known that an analytical solution of this queueing model is difficult …

This paper is dedicated to the study of a machining system with standby provisioning,
feedback and working vacation policy of the server. The failed machines are permitted by …

Motivated by some real stochastic service systems, we study a feedback retrial queue with
customer balking and unreliable servers (servers subject to breakdowns). A customer will …
