RAPID: Identifying and Modeling the Interdependencies of Restoration Efforts across Infrastructures

这一快速研究拨款(RAPID)奖的目的是调查在应对极端事件时基础设施系统之间恢复相互依存的概念。恢复相互依赖被定义为基础设施管理者在关于其基础设施恢复的决策中考虑另一基础设施的恢复努力的需要。例如，在重建或更换某一地区的电力线之前，可能需要清除该地区的碎片。这将意味着瓦砾清除和电力基础设施之间的优先相互依存关系：在电力基础设施恢复工作开始的事件(重建)之前，瓦砾清除中需要发生一个事件。这项研究试图通过(1)采访参与恢复工作的基础设施管理人员和(2)分析电子媒体，来确定、分类和确定飓风桑迪过后恢复相互依赖的频率。这项研究的结果将有助于提高我们对基础设施管理者在确定基础设施恢复工作时必须考虑的因素的了解，从而有助于提高社区的弹性。这一分析将帮助基础设施管理人员更好地了解恢复工作所需的协调或信息共享程度，以便考虑到这些恢复工作的相互依存关系。它将进一步帮助确定应如何规划恢复工作，以便有力地处理恢复相互依存关系，从而缩短在发生极端事件后恢复重要服务所需的时间。

The objective of this Rapid Research Grant (RAPID) award is to investigate the concept of restoration interdependencies amongst infrastructure systems in responding to extreme events. A restoration interdependency is defined as the need for an infrastructure manager to consider the restoration efforts of another infrastructure in decision-making about his or her infrastructure's restoration. For example, debris may need to be cleared from an area prior to rebuilding or replacing power lines in that area. This would imply a precedence interdependency between the debris removal and the power infrastructure: an event needs to occur in the debris removal prior to an event (the rebuilding) starting in the power infrastructure's restoration efforts. This research seeks to identify, classify, and determine the frequency of restoration interdependencies after Hurricane Sandy by (1) interviewing infrastructure managers involved in the restoration efforts and (2) analyzing electronic media. The results of this research will contribute to the resiliency of a community by enhancing our knowledge of what an infrastructure manager must consider in determining an infrastructure's restoration efforts. This analysis will help infrastructure managers better understand the level of coordination or information-sharing required across restoration efforts in order to take into account these restoration interdependencies. It will further help determine how restoration efforts should be planned to robustly handle restoration interdependencies, thereby shortening the time required for the restoration of vital services after an extreme event.
