A survey on retrial queues [PDF]
Queueing Systems, 1987 A systematized survey of the analytic results for retrival queues is given by discussing a generalized model A/B/s/m/O/H. Here, A and B describe the interarrival and service time distribution, respectively, s denotes the number of waiting positions in the queue, O is the capacity of an orbit for the retrying customers and \(H=\{H_ k\), \(k\geq 0 ...

Unreliable M[X]/G(P1,P2)/1 feedback retrial queues with combined working vacation [PDF]
HeliyonThe study examines M[X]/G(P1,P2)/1 feedback retrial queues coupled with starting failure, repair, delay to repair, working vacation, and general retrial times.

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

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

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.

Retrial Queues with Unreliable Servers and Delayed Feedback
Mathematics, 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 ...

Mathematics, 2023 We study the robustness of the cμ-rule for the optimal allocation of a resource consisting of one unreliable server to parallel queues with two different classes of customers.

Approximation of the steady state system state distribution of the M/G/1 retrial queue with impatient customers [PDF]
Yugoslav Journal of Operations Research, 2012 For M/G/1 retrial queues with impatient customers, we review the results, concerning the steady state distribution of the system state, presented in the literature.

Asymptotic Diffusion Method for Retrial Queues with State-Dependent Service Rate
Mathematics, 2023 In this paper, we consider a retrial queue with a state-dependent service rate as a mathematical model of a node of FANET communications. We suppose that the arrival process is Poisson, the delay duration is exponentially distributed, the orbit is ...

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 ...
