Cím:Analyzing the Effect of Catastrophic Breakdowns with Retrial Queues in a Two-Way Communication System / Attila Kuki, Tamás Bérczes, János Sztrik
Megjegyzések:A two-way communication system is modeled in this paper. A retrial queueing system with a finite and an infinite sources is used in the model. The system has two sources. The first source is finite, the second source is infinite. Jobs from the first source are the primary jobs (requests). They can be called as first order job, as well. Jobs from the second source are the secondary jobs. They can be called as second order job, as well. In case of an idle server, the second order customers are called for service. This situation is said as a special search for customers. The non-reliable server is subject to random breakdowns. Two types of breakdowns are considered: the regular breakdown, when the first or second order customer under service is sent back to the orbit or the infinite source, respectively, and the catastrophic breakdown, when all of the requests at the server and in the orbit are sent back to the corresponding sources. The novelty of this paper is to investigate the effect of catastrophic breakdown in a two-way communication environment. The goal is to determine the steady-state probabilities and the system characteristics. The system balance equations are formulated for different cases, but the analytic solution is very difficult. A software tool is used instead. Figures illustrate the effect of the system parameters on the performance measures in scenarios of regular and catastrophic breakdowns.
