Impact of World Trade Center Disaster on Critical Infrastructure Interdependence

世界痕迹中心灾难对关键基础设施相互依赖的影响这项探索性研究侧重于与2001年9月11日纽约世贸中心(WTC)恐怖袭击的破坏性影响有关的时间敏感型数据和实地研究。这项研究的目的是增加我们关于关键基础设施系统的知识库，并对其相互依存关系进行建模，目的是了解它们在这种类型和规模的灾害中的脆弱性。将使用系统方法来代表1)设计或计划的基础设施相互依存关系；2)袭击的整体和应急响应期间的影响；以及恢复行动期间与相互依存关系有关的影响和需求。许多信息只能在反应的早期阶段才能获得。总统第63号决定将基础设施的相互依存关系确定为关键基础设施保护倡议的一部分。了解相互依存关系是有效分配资金用于我国基础设施的设计、建设、运营、维护、运营和安全的关键。相互依存意味着有可能通过减少冗馀来提高成本效益，以及通过生命线和生命的连锁损失产生灾难性的脆弱性。这项研究的结果将用于确定减少脆弱性的机会，制定减轻中断影响的对策，并指导应对和恢复行动。

Impact of the World Trace Center Disaster on Critical Infrastructure InterdependenceThis exploratory research focuses on time sensitive data and field research related to the devastating impacts of the terrorist attacks on the World Trade Center (WTC) in New York City, NY on September 11, 2001. The objective of this research is to increase our knowledge base of and model the interdependencies of critical infrastructure systems with the aim of understanding their vulnerabilities to disasters of this type and scale. A systems approach will be used to represent 1) designed or intended infrastructure interdependencies; 2) the impacts of the attack overall and during emergency response; and the effects and needs related to interdependencies during recovery operations. Much of the information will only be available in the early phases of response. Infrastructure interdependencies have been identified by Presidential Decision Directive 63 as a part of the Critical Infrastructure Protection initiative. Understanding interdependencies is key to efficient funds allocation for design, construction, operations, maintenance, operations and security of our nation's infrastructure. Interdependencies imply the potential for cost-efficiencies through redundancy reductions as well as disastrous vulnerabilities through cascading losses of lifelines and lives. This results of this research will be used to identify opportunities for reducing vulnerabilities, developing countermeasures to mitigate the impacts of disruptions, and guide actions for response and recovery.
