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.}, year = {2022}, pages = {144-156} } @inproceedings{MTMT:32715151, title = {Analysis of Two-Way Communication Retrial Queuing Systems with Non-reliable Server, Impatient Customers to the Orbit and Blocking Using Simulation}, url = {https://m2.mtmt.hu/api/publication/32715151}, author = {Tóth, Ádám and Sztrik, János and Bérczes, Tamás and Kuki, Attila}, booktitle = {Distributed Computer and Communication Networks : 24th International Conference, DCCN 2021, Moscow, Russia, September 20–24, 2021, Revised Selected Papers}, doi = {10.1007/978-3-030-97110-6_13}, unique-id = {32715151}, year = {2022}, pages = {174-185} } @inproceedings{MTMT:32557234, title = {Modeling of non-reliable retrial queueing systems with collisions and catastrophic breakdowns}, url = {https://m2.mtmt.hu/api/publication/32557234}, author = {Kuki, Attila and Bérczes, Tamás and Tóth, Ádám and Sztrik, János}, booktitle = {Distributed computer and communication networks: control, computation, communications (DCCN-2021)}, unique-id = {32557234}, year = {2021}, pages = {148-154} } @inproceedings{MTMT:32557222, title = {Simulation of Two-Way Communication Retrial Queuing Systems With Non-reliable Server, Impatient Customers to the Orbit and Blocking}, url = {https://m2.mtmt.hu/api/publication/32557222}, author = {Tóth, Ádám and Sztrik, János and Bérczes, Tamás and Kuki, Attila}, booktitle = {Distributed computer and communication networks: control, computation, communications (DCCN-2021)}, unique-id = {32557222}, year = {2021}, pages = {66-73} } @misc{MTMT:32526821, title = {Modeling two-way communication systems with catastrophic breakdowns}, url = {https://m2.mtmt.hu/api/publication/32526821}, author = {Kuki, Attila and Bérczes, Tamás and Sztrik, János}, unique-id = {32526821}, year = {2021} } @misc{MTMT:32266290, title = {Modeling of non-reliable retrial queueing systems with collisions and catastrophic breakdowns}, url = {https://m2.mtmt.hu/api/publication/32266290}, author = {Kuki, Attila and Bérczes, Tamás and Tóth, Ádám and Sztrik, János}, unique-id = {32266290}, year = {2021} } @misc{MTMT:32265955, title = {Simulation of Two-Way Communication Retrial Queuing Systems With Non-reliable Server, Impatient Customers to the Orbit and Blocking}, url = {https://m2.mtmt.hu/api/publication/32265955}, author = {Tóth, Ádám and Bérczes, Tamás and Kuki, Attila and Sztrik, János}, unique-id = {32265955}, year = {2021} } @inproceedings{MTMT:32255778, title = {Reliability analysis of a retrial queueing systems with collisions, impatient customers, and catastrophic breakdowns}, url = {https://m2.mtmt.hu/api/publication/32255778}, author = {Kuki, Attila and Bérczes, Tamás and Sztrik, János and Tóth, Ádám}, booktitle = {2021 International Conference on Information and Digital Technologies (IDT)}, doi = {10.1109/IDT52577.2021.9497613}, unique-id = {32255778}, year = {2021}, pages = {254-259} } @article{MTMT:32032486, title = {A contribution to scheduling jobs submitted by finite-sources in computational clusters}, url = {https://m2.mtmt.hu/api/publication/32032486}, author = {Kuki, Attila and Bérczes, Tamás and Tóth, Ádám and Sztrik, János}, doi = {10.33039/ami.2021.03.008}, journal-iso = {ANN MATH INFORM}, journal = {ANNALES MATHEMATICAE ET INFORMATICAE}, volume = {53}, unique-id = {32032486}, issn = {1787-5021}, year = {2021}, eissn = {1787-6117}, pages = {201-218} }
