%0 Journal Article %T On Sojourn Times in the Finite Capacity $M/M/1$ Queue with Processor Sharing %A Qiang Zhen %A Charles Knessl %J Mathematics %D 2009 %I arXiv %R 10.1016/j.orl.2009.09.007 %X We consider a processor shared $M/M/1$ queue that can accommodate at most a finite number $K$ of customers. We give an exact expression for the sojourn time distribution in the finite capacity model, in terms of a Laplace transform. We then give the tail behavior, for the limit $K\to\infty$, by locating the dominant singularity of the Laplace transform. %U http://arxiv.org/abs/0907.2908v1
