SGER: The Impact of Breakdowns of Physical Infrastructure on Social Networks

纽约市世贸中心恐怖袭击的性质表明，有必要了解实体基础设施和社会网络之间的相互依赖关系。这种理解的好处可能包括对修改物理基础设施的设计提出建议，以提高其对灾难性破坏的恢复能力。依赖无线和有线通信基础设施的社交网络模型将允许开发和测试有效的算法，以确定基础设施中的关键块，这些块的分散将对社交网络内部和之间的通信流量产生不利影响。该研究项目将使用图论方法对社会网络及其对物理基础设施的依赖进行建模，主要侧重于纽约市地区的社会网络及其提供的基础设施，包括电话网络、无线通信发射塔、运输和应急服务。这些知识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，并指导及时响应和发现的行动。

The nature of the terrorist attacks on the World Trade Center in New York City demonstrates the need for understanding the interdependencies between physical infrastructure and social networks. The benefits of such understanding may include possible recommendations on modifying the design of the physical infrastructures to improve their resilience to catastrophic disruptions. Models of social networks relying on wireless and wired communication infrastructures would allow the development and testing of efficient algorithms to determine critical blocks in the infrastructures, whose distraction will adversely affect the communication traffic inside of and among social networks. This research project will use the graph-theoretic approach to model social networks and their reliance on physical infrastructures, focusing mainly on social networks in the New York City area and the providing infrastructures, including telephone networks, towers for the wireless communication, transportation and emergency services. This knowledge will be used to identify opportunities for reducing vulnerabilities, developing countermeasures to mitigate the impact of disruptions, and guiding actions for timely response and discovery.
