Retrial queues with constant retrial times
Queueing Systems, 2022 The paper under review studies a single server queueing system without buffer. Customers arrive in the queue according to a Poisson process with rate \(\lambda\) and immediately receive the service, if the server is available. If the server is busy, the customer joins the orbit and retries after a deterministic time \(S\).

Stability of retrial queues with versatile retrial policy [PDF]
International Journal of Stochastic Analysis, 2006 We consider in this paper the stability of retrial queues with a versatile retrial policy. We obtain sufficient conditions for the stability by the strong coupling convergence to a stationary ergodic regime for various models of retrial queues including a model with two types of customers, a model with breakdowns of the server, a model with negative ...

On the single-server retrial queue [PDF]
Yugoslav Journal of Operations Research, 2006 In this work, we review the stochastic decomposition for the number of customers in M/G/1 retrial queues with reliable server and server subjected to breakdowns which has been the subject of investigation in the literature.

Stability of retrial queueing system with constant retrial rate [PDF]
, 2014 We study the stability of a single-server retrial queueing system with constant retrial rate and general input and service processes. In such system the external (primary) arrivals follow a renewal input with rate $\lambda$. The system also has service times with rate $\mu$.

Optimal Pricing Analysis of Computer Networks Based on a Queueing System With Retrial Mechanism
IEEE Access, 2020 We consider a single-server retrial queue with a Poisson arrival process and exponential service times, where the server is unreliable. Assume there is no waiting space in front of the server and the customer who finds the server unavailable joins an ...

Study of feedback retrial queueing system with working vacation, setup time, and perfect repair
Ratio Mathematica, 2021 This manuscript analyses a retrial queueing system with working vacation, interruption, feedback, and setup time with the perfect repair. In the proposed model, the server takes vacation whenever the system gets empty but it still serves the customers at

Waiting Time Distribution and Some Characteristics in Finite Queueing Systems with Retrials [PDF]
The Egyptian Statistical Journal, 2001 A retrial queueing system consists of a primary service facility of finite capacity and an orbit. Customers arrive from outside the system according to Poisson process, or from the orbit according to a rate that depends upon the number of customers in ...

Ural Mathematical Journal, 2022 This paper explores the two-commodity (TC) inventory system in which commodities are classified as major and complementary items. The system allows a customer who has purchased a free product to conduct Bernoulli trials at will.

Bounds and Maxima for the Workload in a Multiclass Orbit Queue
Mathematics, 2023 In this research, a single-server M-class retrial queueing system (orbit queue) with constant retrial rates and Poisson inputs is considered. The main purpose is to construct the upper and lower bounds of the stationary workload in this system expressed ...
