On the Convergence of Truncated Processes of Multiserver Retrial Queues
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 counterparts, without providing a rigorous mathematical proof. In this paper we demonstrate the convergence of finite truncated models with two r...
متن کاملMultiserver Retrial Queues with After-call Work
This paper considers a multiserver queueing system with finite capacity. Customers that find the service facility being fully occupied are blocked and enter a virtual waiting room (called orbit). Blocked customers stay in the orbit for an exponentially distributed time and retry to occupy an idle server again. After completing a service, the server starts an additional job that we call an after...
متن کاملMultiserver retrial Queues with Two Types of nonpersistent Customers
We consider M/M/c/K (K ≥ c ≥ 1) retrial queues with two types of nonpersistent customers, which are motivated from modelling of service systems such as call centers. Arriving customers that see the system fully occupied either join the orbit or abandon receiving service forever. After an exponentially distributed time in the orbit, each customer either abandons the system forever or retries to ...
متن کاملMultiserver Retrial Queues with Finite Number of Heterogeneous Sources∗
The aim of this paper is to investigate a multiserver retrial queueing system with a finite number of heterogeneous sources of calls. The novelty of the investigation is the heterogeneity of the sources, that is every source is characterized by different arrival, retrial and service rates. All random variables involved in the model construction are assumed to be exponentially distributed and in...
متن کاملA matrix continued fraction approach to multiserver retrial queues
We consider basic M/M/c/c (c ≥ 1) retrial queues where the number of busy servers and that of customers in the orbit form a level-dependent quasi-birth-and-death (QBD) process with a special structure. Based on this structure and a matrix continued fraction approach, we develop an efficient algorithm to compute the joint stationary distribution of the numbers of busy servers and retrial custome...
