      Queueing systems constitute a central tool in modeling and performance analysis. These types of systems are in our everyday life activities, and the theory of queueing systems was developed to provide models for forecasting ...
    • A Discrete-Time retrial queueing system with service upgrade 

      Fortes, Inmaculada; Sánchez, Sixto; Atencia-McKillop, Ivan (2015-06-10)
      We study the Markov chain underlying the considered queueing system obtaining the gen- erating function of the number of customers in the orbit and in the system as well as the stationary distribution of the time that a ...
    • A discrete-time system with uncertainty information 

      Atencia-McKillop, Ivan; Fortes, Inmaculada; Sánchez, Sixto (2017-02-14)
      This paper considers a discrete-time queueing system with uncertainty information, that is, an arriving customer may opt, with a certain probability, to be served under a Last Come First Served (LCFS) discipline or, with ...
