Bounds and Comparisons for Some Queueing Systems.
Abstract
Bounds and comparisons for various performance measures in tandem queueing systems and loss systems are studied. Using a definition of variability of random variables, it is proven that for a tandem queueing system with n stations in series, where each station can have either one server with an arbitrary service distribution or a number of constant servers in parallel, the expected total waiting time in system of every customer decreases as the variability of interarrival and service distributions decreases. A new sufficient condition for customer average delay to be smaller (larger) than time average delay in single server queues is also given.
