On retrial queues with controlled input flow

open access: yes, 2009
Дослiджуються марковськi системи з повторними викликами i керованою iнтенсивнiстю вхiдного потоку. Для моделей такого типу знайденi умови iснування стацiонарного режиму, одержанi явнi формули та ефективнi алгоритми розрахунку стацiонарних iмовiрностей ...

A Two-Phase Service Access Beside Retrial Queues, Orbit Mechanism, Working Vacation Policies for Single Server Environments

open access: yesمجلة بغداد للعلوم
This paper analyzes the M/G (P1, P2)/1 queue using a single server that provides essential services in both the first phase (FPS) and the second phase (SPS).

Improving the Efficiency of a Message Validation System in a Vehicular Ad Hoc Network

open access: yesJournal of Computer Networks and Communications, Volume 2025, Issue 1, 2025.
Advancements in communication technologies have enabled vehicles to be equipped with computing devices, facilitating communication and autonomous operations. This has led to the emergence of a new networking paradigm known as the vehicular ad hoc Network (VANET).

Standard and retrial queueing systems: a comparative analysis

open access: yes, 2002
We describe main models and results of a new branch of the queueing theory, theory of retrial queues, which is characterized by the following basic assumption: a customer who cannot get service (due to finite capacity of the system, balking, impatience ...

A Multi-Server Retrial Queueing Model with Poisson Signals

open access: yes, 2021
Retrial queueing models have been studied extensively in the literature. These have many practical applications, especially in service sectors. However, retrial queueing models have their own limitations.

Model Validation and Strategy Analysis in Retrial Queues with Delayed Vacations and Feedback Based on Monte Carlo Simulation

open access: yesMathematics
Inspired by call centers, this paper models them as a constant retrial queue, with feedback and delayed vacations to balance high efficiency and low cost for service agents. After completing the service, the server randomly waits for an idle period.

Performance Analysis of Two Different Types of Waiting Queues with Working Vacations

open access: yesJournal of Mathematics
This work examines a new class of working vacation queueing models that contain regular (original) and retrial waiting queues. Upon arrival, a customer either starts their service instantly if the server is available, or they join the regular queue if ...

On the Convergence of Truncated Processes of Multiserver Retrial Queues

open access: yes, 2010
Retrial queues can only be solved in a closed form in very few and simple cases, so researchers must resort to approximate models. However, most of the papers that propose approximate models assume the convergence of the proposed models to their exact ...

Threshold Policies for Controlled Retrial Queues with Heterogeneous Servers

open access: yes, 2006
Retrial queues are an important stochastic model for many telecommunication systems. In order to construct competitive networks it is necessary to investigate ways for optimal control. This paper considers K -server retrial systems with arrivals governed

Retrial queues with variable rate of input flow

open access: yes, 2013
Розглянуто системи з повторними викликами типу MQ / M / m / ∞ зі змінною інтенсивністю вхідного потоку, для яких знайдено умову існування стаціонарного режиму. Для розрахунку стаціонарних ймовірностей використано метод апроксимації.
