RT Conference Proceedings T1 Queueuing system with failures and priorities A1 Atencia-McKillop, Iván A1 Galán-García, José Luis A1 Aguilera-Venegas, Gabriel A1 Rodríguez, Pedro A1 Galán-García, María Ángeles K1 Sistemas de tiempo discreto AB Queueing theory provides models, structural insights, problem solutions andalgorithms to many application areas. Due to its practical applicability toproduction, manufacturing, home automation, communications technology,etc, more and more complex systems requires more elaborated models, tech-niques, algorithm, etc. need to be developed. Discrete-time models are verysuitable in many situations and a feature that makes the analysis of discretetime systems technically more involved than its continuous time counterparts.In this paper we consider a discrete-time queueing system were failures inthe server can occur as-well as priority messages. The possibility of failuresof the server with general life time distribution is considered. We carry outan extensive study of the system by computing generating functions for thesteady-state distribution of the number of messages in the queue and in thesystem. We also obtain generating functions for the stationary distributionof the busy period and sojourn times of a message in the server and in thesystem. Performance measures of the system are also provided. YR 2016 FD 2016-07-07 LK http://hdl.handle.net/10630/11772 UL http://hdl.handle.net/10630/11772 LA eng NO Universidad de Málaga.
