Stability analysis of a multiclass retrial system with classical retrial policy
Performance Evaluation, 2017We consider a multiserver retrial queueing system with a renewal input, K classes of customers, and a finite buffer. Service times are class-dependent, however, for each class, are independent, identically distributed (iid). A new class-i customer joins the primary system (servers and buffer), otherwise, if all servers and buffer are full, he joins the

APPROXIMATION OF PH/PH/c RETRIAL QUEUE WITH PH-RETRIAL TIME
Asia-Pacific Journal of Operational Research, 2014We consider the PH/PH/c retrial queues with PH-retrial time. Approximation formulae for the distribution of the number of customers in service facility, sojourn time distribution and the mean number of customers in orbit are presented. We provide an approximation for GI/G/c retrial queue with general retrial time by approximating the general ...

NUMBER OF RETRIALS IN A FINITE SOURCE RETRIAL QUEUE WITH UNRELIABLE SERVER
Asia-Pacific Journal of Operational Research, 2014The object of this paper is to continue investigation of a single server retrial queue with finite number of sources in which the server is subjected to breakdowns and repairs. The server life time as well as the intervals between repetitions are exponentially distributed, while the repair and the service times are generally distributed.

A Model of Rational Retrials in Queues
SSRN Electronic Journal, 2014Customers often wait in queues before being served. Because waiting is undesirable, customers may come back later (i.e., retry) when the queue is too long. However, retrial attempts can be costly as a result of transportation fees and service delays. This paper introduces a framework for rational retrial decisions in stationary queues.

Reducing Delay in Retrial Queues by Simultaneously Differentiating Service and Retrial Rates
Operations Research, 2020Customer retrials commonly occur in many service systems, such as healthcare, call centers, mobile networks, computer systems, and inventory systems. However, because of their complex nature, retrial queues are often more difficult to analyze than queues without retrials.

A Finite Source Retrial Queue: Number of Retrials
Communications in Statistics - Theory and Methods, 2013We consider a single-server queuing system with a finite number of sources, where customers are not allowed to queue; instead of that, they make repeated attempts, or retrials, in order to enter service after some time. This queuing system and its variants are widely used to model disk memory systems, star-like local area networks, and other ...

ESTIMATORS OF THE RETRIAL RATE IN M/G/1 RETRIAL QUEUES
Asia-Pacific Journal of Operational Research, 2006In this article we analyze the M/G/1 retrial queue from a statistical viewpoint. Assuming that retrials are exponentially distributed we focus on the estimation of the retrial parameter for constant and non-constant retrial policies, including the non-ergodic case. We consider different estimators and compare their asymptotic variances.
