基于序贯资源分配的动态流行病控制

Dynamic Epidemic Control via Sequential Resource Allocation

Mathilde Fekom, Nicolas Vayatis, Argyris Kalogeratos

摘要:

在动态资源分配(Dynamic Resource Allocation,简称DP)问题中,管理员必须将有限数量的资源分配给网络的节点,以便减少扩散过程(diffusion process,简称DP)(例如,流行病)。在本文中,我们提出了一个多轮的动态控制框架,我们实现了通过两个衍生模型:限制和顺序的控制(RSDRA,SDRA),允许限制信息和访问整个网络,相反,标准的全信息和全访问控制模型。在每一轮干预中,管理员只能访问一小部分网络节点,前者是同时访问,后者是顺序访问。这个顺序方面的决策过程中提供了一个全新的视角,动态DP控制,使这项工作的第一个投动态控制问题作为一系列的顺序选择问题。通过深入的SIS流行病模拟,我们比较了我们的多轮方法与其他资源分配策略和几个顺序选择算法的性能生成,和真实的数据网。结果提供了证据的效率和适用性的建议框架,为现实生活中的问题。

英文摘要:

In the Dynamic Resource Allocation (DRA) problem, an administrator has to allocate a limited amount of resources to the nodes of a network in order to reduce a diffusion process (DP) (e.g. an epidemic). In this paper we propose a multi-round dynamic control framework, which we realize through two derived models: the Restricted and the Sequential DRA (RDRA, SDRA), that allows for restricted information and access to the entire network, contrary to standard full-information and full-access DRA models. At each intervention round, the administrator has only access -- simultaneous for the former, sequential for the latter -- to a fraction of the network nodes. This sequential aspect in the decision process offers a completely new perspective to the dynamic DP control, making this work the first to cast the dynamic control problem as a series of sequential selection problems. Through in-depth SIS epidemic simulations we compare the performance of our multi-round approach with other resource allocation strategies and several sequential selection algorithms on both generated, and real-data networks. The results provide evidence about the efficiency and applicability of the proposed framework for real-life problems.
