Impact of World Trade Center Disaster on Critical Infrastructure Interdependence

世界追踪中心灾难对关键基础设施相互依赖的影响本探索性研究侧重于与2001年9月11日纽约世界贸易中心（WTC）恐怖袭击的破坏性影响相关的时间敏感数据和实地研究。这项研究的目的是增加我们对关键基础设施系统相互依赖关系的知识基础和建模，以了解它们对这种类型和规模的灾害的脆弱性。系统方法将用于表示1)设计的或预期的基础设施相互依赖性；2)攻击对整体和应急响应的影响；以及恢复行动中相互依赖关系的影响和需求。大部分信息只能在应对的早期阶段获得。基础设施的相互依赖性已被第63号总统决定指令确定为关键基础设施保护倡议的一部分。了解相互依赖关系是有效分配我国基础设施设计、建设、运营、维护、运营和安全资金的关键。相互依赖意味着通过减少冗余来提高成本效率的潜力，以及通过生命线和生命的级联损失来带来灾难性的脆弱性。这项研究的结果将用于确定减少脆弱性的机会，制定对策以减轻中断的影响，并指导响应和恢复行动。

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.
