复杂网络方法已被用于分析物理或社会网络。以前的研究往往侧重于研究单一的、孤立的系统，而忽略了这样一个事实，即许多这样的系统正在发展成为一个“网络网络”。多年来，这些系统之间的联系越来越紧密。由于这种相互依赖关系，一个网络组件的故障可能会在整个系统系统中传播，从而导致级联故障。这项研究从“系统系统”的角度研究相互依赖的网络，并开发了一套工具来分析基础设施网络及其相关的相互依赖关系。这项研究的目的是促进对基础设施网络及其之间相互依赖的影响的系统规模的理解。这一认识可用于改进基础设施的设计，使其对自然和人为灾害更具弹性和适应性。
Complex network approaches have been used to analyse physical or social networks. Previous research has tended to focus on studying single, isolated systems and ignores the fact that many of these systems are developing into a “network of networks”. Over the years these systems have become increasingly interconnected. Due to this interdependence the failure of one network component may propagate across the system of systems, resulting in cascading failure. This research studies interdependent networks from a “system-of-systems” perspective, and a suite of tools have been developed to analyse infrastructure networks and their associated interdependencies. The aim of this research is to facilitate system-scale understanding of infrastructure networks and the implications of interdependencies between them. This understanding could be used to improve the design of infrastructure that is more resilient and adaptable to natural and manmade hazards.
