摘要

我们考虑了一个经典的问题,即在队列中抢占调度未知大小的作业(即服务时间),以最小化平均系统数,或等效的平均响应时间(即逗留时间)。我们知道如何在M/G/1中解决这个问题,前提是调度程序知道作业大小的分布。在这种情况下,最优策略是Gittins策略(又称Gittins索引策略)[1]。

Performance of the Gittins Policy in the G/G/1 and G/G/k, With and Without Setup Times
We consider the classic problem of preemptively scheduling jobs of unknown size (a.k.a. service time) in a queue to minimize mean number-in-system, or equivalently mean response time (a.k.a. sojourn time). We know how to solve this problem in an M/G/1, provided the job size distribution is known to the scheduler. In this case, the optimal policy is the Gittins policy (a.k.a. Gittins index policy) [1].
