我们考虑一个由多个客户类和服务器池并行组成的并行服务器系统。我们提出了一种简单的鲁棒控制策略来最小化线性持有和退出的总代价。当服务时间仅与服务器池相关且服从指数分布时，我们证明了该策略在多服务器大流量并行服务器系统中是渐近最优的。
We consider a parallel server system that consists of several customer classes and server pools in parallel. We propose a simple robust control policy to minimize the total linear holding and reneging costs. We show that this policy is asymptotically optimal under the many-server heavy traffic regime for parallel server systems when the service times are only server pool dependent and exponentially distributed.
