Queueing system with a constant retrial rate, non-reliable server and threshold-based recovery

In this paper, we examine a Markovian queueing system which is composed of a retrial queue with constant retrial rate and a non-reliable server. Upon arrival a customer occupies the server if it is idle, otherwise it goes to the retrial queue.

Matrix analytic methods for a multi-server retrial queue with buffer

Top, 1999
In the paper reviewed above the authors have studied single server retrial queues. In this paper, they extend their results for multi-server retrial queues with Markovian arrival process, phase type service time distribution with two states and finite buffer.

Analysis of a multi-server retrial queue with search of customers from the orbit

Performance Evaluation, 2006
We consider a multi-server retrial queueing model in which customers arrive according to a Markovian arrival process (MAP). An arriving customer finding a free server enters into service immediately; otherwise the customer enters into an orbit of infinite size.

On the multi-server retrial queue with geometric loss and feedback: computational algorithm and parameter optimization

International Journal of Computer Mathematics, 2011
We consider an M/M/c retrial queue with geometric loss and feedback. An arriving customer finding a free server enters into service immediately; otherwise the customer either enters into an orbit to try again after a random amount of time or leave the system without service.

The infinite server queue and heuristic approximations to the multi-server queue with and without retrials

Top, 1999
This paper discusses three topics: (1) monotonicity properties of the transition probabilities for the initially empty \(\text{M}_t/ \text{G}/ \infty\) queue, and qualitative similarities with the M/M/1 queue; (2) a comparison of such probabilities for \(\text{M/M/}m/m\) and \(\text{M/M/}\infty\) queues; and (3) decomposition formulae for operating ...

An M/M/1 retrial queue with unreliable server

Operations Research Letters, 2006
We analyze an unreliable M/M/1 retrial queue with infinite-capacity orbit and normal queue. Retrial customers do not rejoin the normal queue but repeatedly attempt to access the server at i.i.d. intervals until it is found functioning and idle.
