A study on M/G/1 feedback retrial queue with subject to server breakdown and repair under multiple working vacation policy

open access: yesAlexandria Engineering Journal, 2018
In this paper, we consider a single server feedback retrial queueing system with multiple working vacations and vacation interruption. An arriving customer may balk the system at some particular times.

Asymptotics of queue length distributions in priority retrial queues [PDF]

open access: yesPerformance Evaluation, 2018
We calculate asymptotics of the distribution of the number of customers in orbit in a two-class priority retrial $M/G/1$-type queueing model. In this model, priority customers wait in line while non-priority customers join an orbit and retry later. Although the generating function and moments of the number of customers in orbit has been analyzed before,

Discrete-time retrial queue with Bernoulli vacation, preemptive resume and feedback customers

open access: yesJournal of Industrial Engineering and Management, 2015
Purpose: We consider a discrete-time Geo/G/1 retrial queue where the retrial time follows a general distribution, the server subject to Bernoulli vacation policy and the customer has preemptive resume priority, Bernoulli feedback strategy.

Waiting Time Control Chart for M/G/1 Retrial Queue

open access: yesComputation
Retrial queues are used extensively to model many practical problems in service systems, call centers, data centers, and computer network systems. The average waiting time is the main observable characteristic of the retrial queues. Long queues may cause

Spectrum Renting with Two Finite Source Pools in Mobile Cellular Networks

open access: yesCommunications, 2015
Spectrum renting is a technique for improving the efficiency of spectrum usage and alleviating the scarcity of the available spectrum in mobile cellular networks. Since the first proposal of spectrum pooling, several works have been done in this area. In

Multi-Server Two-Way Communication Retrial Queue Subject to Disaster and Synchronous Working Vacation

open access: yesAlgorithms
This research analyzes a multi-server retrial queue with two types of calls: working vacation and working breakdown. The incoming call may enter the retrial queue and attempt to seize a server after a random delay if all the servers are unavailable upon ...

A matrix continued fraction approach to multiserver retrial queues [PDF]

open access: yes, 2013
We consider basic M/M/c/c (c≥1) retrial queues where the number of busy servers and that of customers in the orbit form a level-dependent quasi-birth-and-death (QBD) process with a special structure.

Reliability Analysis of a Limited-Capacity Dual-Repair System with Hybrid Vacation Policies [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences
This study investigates the reliability of a machine dual-repair system (MDRS) with limited capacity and multiple operational vacations (OV). Multiple operational vacation is a mechanism that involves the process of the two types of vacation, one as ...
