使用记忆控制不可观测队列的准入
Using memory to control admission to unobservable queues
AI总结:
针对不可观测M/M/1队列,提出门控准入策略(GA)在等吞吐量下随机优于随机路由(RR),并证明在任何逗留成本下提升社会福利,同时刻画福利最大化阈值并定义遗忘代价。
摘要:
我们研究不可观测M/M/1队列的准入控制。无记忆控制器只能随机稀疏化到达(随机路由,RR)。我们证明门控准入(GA)策略(每次准入后阻塞到达固定时间)在等吞吐量下随机优于RR,在任何基于逗留时间的成本下改善社会福利。我们刻画了福利最大化阈值,并定义遗忘代价为福利比。该比值无界,尽管绝对福利增益一致有界。
英文摘要:
We study admission control to an unobservable M/M/1 queue. A memoryless controller can only randomly thin arrivals (random routing, RR). We show that a gated admission (GA) policy, blocking arrivals for a fixed period after each admission, stochastically dominates RR at equal throughput, improving social welfare under any sojourn-based cost. We characterize the welfare-maximizing threshold and define the Price of Forgetting as the welfare ratio. This ratio is unbounded even though the absolute welfare gain stays uniformly bounded.
