Critical infrastructure networks, including water, power, communication, and transportation, among others, are necessary to society’s functionality. In recent years, the threat of different types of disruptions to such infrastructure networks has become an increasingly important problem to address. Due to existing interdependencies, damage to a small area of one of the networks could have far-reaching effects on the ability to meet demand across the entire system. Common disruption scenarios include, among others, intentional malevolent attacks, natural disasters, and random failures. Similar works have focused on only one type of scenario, but combining a variety of disruptions may lead to more realistic results. Additionally, the concept of social vulnerability, which describes an area’s ability to prepare for and respond to a disruption, must be included. This should promote not only the protection of the most at-risk components but also ensure that socially vulnerable communities are given adequate resources. This work provides a decision making framework to determine the allocation of defensive resources that accounts for all these factors. Accordingly, we propose a multi-objective mathematical model with the objectives of: (i) minimizing the vulnerability of a system of interdependent infrastructure networks, and (ii) minimizing the total cost of the resource allocation strategy. Moreover, to account for uncertainty in the proposed model, this paper incorporates a means to address robustness in finding the most adaptable network protection plan to reduce the vulnerability of the system of interdependent networks to a variety of disruption scenarios. The proposed work is illustrated with an application to social vulnerability and interdependent power, gas, and water networks in Shelby County, Tennessee.

社区漏洞对相互依赖的基础架构网络中强大的保护计划的看法

关键的基础设施网络,包括水,电,通讯和运输等,对于社会的功能而言是必不可少的。近年来,对此类基础设施网络的不同类型破坏的威胁已成为日益重要的问题。由于现有的相互依赖关系,对其中一个网络的一小部分区域的损坏可能会对满足整个系统需求的能力产生深远的影响。常见的破坏情况包括故意破坏性攻击,自然灾害和随机故障。相似的作品仅关注一种类型的场景,但是将各种干扰结合起来可能会导致更实际的结果。此外,社会脆弱性的概念描述了一个地区为破坏做好准备并做出响应的能力,必须包括在内。这不仅应促进对高风险人群的保护,而且应确保向社会弱势群体提供足够的资源。这项工作提供了一个决策框架来确定考虑所有这些因素的防御性资源的分配。因此,我们提出了一个多目标数学模型,其目标是:(i)最小化相互依赖的基础架构网络系统的脆弱性,以及(ii)最小化资源分配策略的总成本。此外,为解决所提出模型的不确定性,本文采用一种方法来解决鲁棒性问题,以找到最适合的网络保护计划,以减少相互依存的网络系统在各种中断情况下的脆弱性。
