Extreme events can damage or destroy multiple supply chain interdependent critical infrastructures elements. Although much research has focused on developing efficient restoration strategies, and/or making critical infrastructures more resilient, practitioners need tools to determine resources necessary to restore such damage. The methodology developed in this research estimates both the resources required to support the repair personnel, and restore different infrastructure elements. This method uses a dynamic mathematical model that establishes a framework to estimate post-disaster restoration costs from a whole system perspective. The model is validated with a case study of the resources required to restore multiple infrastructures that were damaged by the EF-5 tornado that struck Joplin, Missouri on May 22, 2011. Engineering managers, city planners, and policy makers can use the methodologies developed in this research to develop effective disaster planning schemas and to prioritize post-disaster restoration operations.

极端事件可能损坏或破坏多个供应链相互依赖的关键基础架构要素。尽管许多研究都集中在开发有效的恢复策略和/或使关键基础架构更具弹性，但从业人员仍需要工具来确定恢复此类损坏所需的资源。这项研究中开发的方法估计了支持维修人员和恢复不同基础架构元素所需的资源。该方法使用动态数学模型，该模型建立了一个框架来从整个系统的角度估算灾后恢复成本。该模型通过案例研究进行了验证，该案例研究用于恢复遭到EF-5龙卷风破坏的多个基础设施所需的资源，而EF-5龙卷风于2011年5月22日袭击了密苏里州的乔普林。
