A single server queue with Markov modulated service rates and impatient customers

B Kim, J Kim - Performance Evaluation, 2015 - Elsevier
We consider a single server queue in which the customers wait for service for a fixed time
and leave the system if the service has not begun within that time. The customers arrive …

Solving multi-regime feedback fluid queues

HE Kankaya, N Akar - Stochastic Models, 2008 - Taylor & Francis
In this paper, we study Markov fluid queues with multiple thresholds, or the so-called multi-
regime feedback fluid queues. The boundary conditions are derived in terms of joint …

Transient and first passage time distributions of first-and second-order multi-regime Markov fluid queues via ME-fication
