6月29日上午，美国普渡大学Satish Ukkusuri教授应邀来访我院，并在新主楼A716房间作了题为“Resilience of Cities : Complexity, Social Networks and Interdependence”的学术报告。报告会由田琼教授主持、我院相关领域20余名师生参加。
Ukkusuri教授首先介绍了网络的一些基本特性🦼。结合道路网络，从结构和功能的角度介绍了道路网络的两种失灵方式：结构损坏和功能失灵🕗，并从理论和实践两个层面报告了功能失灵的研究价值👩👧👦。Ukkusuri教授提出社交网络与基础设施网络之间相互作用的观点🧝🏼，某一网络功能的发挥依赖于另一网络👨🏼💼，网络间功能的失效与恢复具有高度的相关性👴🏼。Ukkusuri教授在研究中提出了对偶网络的概念，并指出了现实道路网络与对偶网络的对应关系🐕，研究了基于对偶网络条件下的交通拥挤及演变过程。最后🉐，Ukkusuri教授还结合社交媒体数据对灾害预警🐱、响应和恢复进行了讲解🙇🏽。该研究将社交网络与基础设施网络进行了有机的统一👩🦽，整合了网络的结构和功能，提供了一种解释拥挤演化过程的新方式，对灾害预警和重建工作有较强的指导意义。
报告结束后👱♀️，与会人员还就相关问题与Ukkusuri教授进行了深入的交流和探讨。
