Optimization of multi-channel queuing systems with a single retail attempt: Economic approach [PDF]

open access: yesDecision Science Letters, 2020
This paper deals with retrial queues of the |MQ/M/c/∞|- type in which the rate of input flow depends on the number of sources of repeated calls and each call has only one retrial attempt.

A literature review on retrial queueing system with Bernoulli vacation [PDF]

open access: yesYugoslav Journal of Operations Research
The retrial phenomenon occurs inherently in a wide range of queueing systems. The majority of retrial queueing models do not account for vacation. However, in practice, retrial queueing systems undergo vacations for maintenance or other reasons.

Retrial Queuing-Inventory Systems with Delayed Feedback and Instantaneous Damaging of Items

open access: yesAxioms, 2022
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 positive upon their arrival, they instantly receive the items.

Retrial Queues with Unreliable Servers and Delayed Feedback

open access: yesMathematics, 2021
In this paper, models of unreliable multi-server retrial queues with delayed feedback are examined. The Bernoulli retrial is allowed upon the arrival of both primary (from outside) and feedback customers (from orbit), as well as the Bernoulli feedback ...

On a batch arrival queuing system equipped with a stand-by server during vacation periods or the repairs times of the main server [PDF]

open access: yes, 2011
We study a queuing system which is equipped with a stand-by server in addition to the main server. The stand-by server provides service to customers only during the period of absence of the main server when either the main server is on a vacation or it ...

Availability and cost-benefit evaluation for a repairable retrial system with warm standbys and priority

open access: yesStatistical Theory and Related Fields, 2023
This paper investigates a warm standby repairable retrial system with two types of components and a single repairman, where type 1 components have priority over type 2 in use.

Diffusion Limit for Single-Server Retrial Queues with Renewal Input and Outgoing Calls

open access: yesMathematics, 2022
This paper studies a single-server retrial queue with two types of calls (incoming and outgoing calls). Incoming calls arrive at the server according to a renewal process, and outgoing calls of N−1 (N≥2) categories occur according to N−1 independent ...

Spectrum occupancy of cognitive radio networks: a queueing analysis using retrial queue

open access: yesIET Networks, 2014
The authors apply the preemptive priority queueing analysis to cognitive radio networks. Using the proposed analytical model, the authors can quantify the delay, throughput and spectrum occupancy of cognitive radio networks.

A non markovian retrial queueing system [PDF]

open access: yes, 2023
This paper studies a discrete-time queueing system in which a customer who enters in the system with a server occupied may choose to go to the retrial group or to begin its service displacing to the retrial group the customer that was in the server.
