资源分配、竞争和储备的不安分Bandit模型

A Restless Bandit Model for Resource Allocation, Competition and Reservation

Jing Fu, Bill Moran, Peter G. Taylor

摘要:

我们研究的资源分配问题,不断变化的请求,并与资源的有限容量共享的多个请求。它被建模为一组异构的不安的多臂强盗问题(RMABP)连接的资源容量的约束。根据惠特尔的放松的想法和韦伯和韦斯的渐近最优性证明,我们提出了一个简单的政策,并证明它是渐近最优的到达率和容量增加的制度。我们提供了一个简单的充分条件的政策的渐近最优性,并在完整的一般性提出了一种方法,产生一组候选政策,渐近最优性可以检查。数值实验证明了这些结果的有效性。据我们所知,这是第一个工作提供渐近最优结果,这样的资源分配问题,这样的组合多个RMABP。

英文摘要:

We study a resource allocation problem with varying requests, and with resources of limited capacity shared by multiple requests. It is modeled as a set of heterogeneous Restless Multi-Armed Bandit Problems (RMABPs) connected by constraints imposed by resource capacity. Following Whittle's relaxation idea and Weber and Weiss' asymptotic optimality proof, we propose a simple policy and prove it to be asymptotically optimal in a regime where both arrival rates and capacities increase. We provide a simple sufficient condition for asymptotic optimality of the policy, and in complete generality propose a method that generates a set of candidate policies for which asymptotic optimality can be checked. The effectiveness of these results is demonstrated by numerical experiments. To the best of our knowledge, this is the first work providing asymptotic optimality results for such a resource allocation problem and such a combination of multiple RMABPs.
