We consider a multiphase queuing system of type M/M/1/k→∙/M/1/k→⋯→∙/M/1/k with an
arbitrary number of nodes and a common retrial queue of type∙/M/1/k for other queues in the …

Abstract An M/M/1//N retrial queueing system with two-way communication to the infinite
source and impatient customers in the orbit is considered in the paper. There is a finite …

This paper discusses a multi-server retrial queuing system, where the customers may leave
the system due to balking and impatience. Deviated from the classical retrial queue, we use …

We consider a queueing model with N channels and an orbit with infinite waiting positions to
model a specific cell in wireless networks. It is assumed that handoff and new calls have …

The goal of this paper is to carry out a sensitivity analysis to examine the effect of different
distributions of service time when blocking is applied with the help of retrial queueing …

In this work we consider a single-server system accepting N types of retrial customers, which
arrive according to independent Poisson streams. In case of blocking, type-i customer, i= 1 …

A two-way communication, retrial queueing system is considered with a single server which
from time to time is subject to random breakdowns. The investigated model is a M/M/1//N …

We consider a single server retrial queueing model with two types of customers,
abandonment of customers and search for priority customers. Two types of customers …

The aim of the paper is to analyze a M/M/1//N finite-source, two-way communication retrial
queueing system with an unreliable server and impatient customers. In this model, every …

Consider a single server retrial queueing system with negative arrival under Coxian phase
type service in which customers arrive in a Poisson process with arrival rate λ. The negative …
