处理器共享不耐烦

Processor Sharing Queues with Impatience

Christian H. Gromoll, Philippe Robert, Bert Zwart

摘要:

研究了一类服务时间服从一般分布的处理机共享更新排队系统.不耐烦的工作可能会在完成服务之前放弃队列,或反悔。相应的随机过程表示为R^2+上的测度值马氏过程.一个缩放过程,产生一个非平凡的,但易处理的稳态行为的流体模型,提出。这个流体模型模型捕捉了底层随机模型的许多基本特征,它被用来分析处理器共享队列中的不耐烦的影响。

英文摘要:

We investigate a processor sharing queue with renewal arrivals and generally distributed service times. Impatient jobs may abandon the queue, or renege, before completing service. The corresponding stochastic processes are represented by measure valued Markov processes on R^2\_+. A scaling procedure that gives rise to a fluid model with a nontrivial, yet tractable steady state behavior, is presented. This fluid model model captures many essential features of the underlying stochastic model, and it is used to analyze the impact of impatience in processor sharing queues.
