Reducing Delay in Retrial Queues by Simultaneously Differentiating Service and Retrial Rates

Operations Research, 2020
Customer 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.

ESTIMATORS OF THE RETRIAL RATE IN M/G/1 RETRIAL QUEUES

Asia-Pacific Journal of Operational Research, 2006
In 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.

A large deviation analysis of retrial models with constant and classic retrial rates

Performance Evaluation, 2019
Abstract In this paper, a large deviation analysis of the retrial systems is developed. We consider both classical and constant retrial rate models. We focus on the (overflow) probability that the orbit size in the single-server system reaches a high level N within a regeneration period. Under natural assumptions, it is shown that, as N →

A Retrial BMAP/PH/N queueing system with Markov modulated retrials

2012 2nd Baltic Congress on Future Internet Communications, 2012
A retrial multi-server queueing model with a Batch Markovian Arrival Process (BMAP) and phase-type (PH-type) service time distribution is analyzed. The rate of individual repeated attempts from the orbit is modulated according to a Markov Modulated Poisson Process (MMPP).

Schedules and Retrials

2003
This chapter deals with models where customers choose their time of arrival. Such models contain some non-stationary element like known times that a service facility is open, a scheduled (possibly periodic) service, or information about the state of the queue in past instants ...
