| Abstract | To enhance the overall resilience of interconnected CIs as a system-of-systems (SoS), it is important to model the complex inter- and intra-dependencies using an integrated framework. Network flow model is one important approach in studying infrastructure interdependencies. To address some limitations in existing studies of infrastructure network flow models, this study proposed an integrated flow-based model that captures the heterogeneity of nodes, different levels of restoration of disrupted nodes and arcs, and both intra- and inter-dependencies in an infrastructure SoS. The effectiveness of the proposed model is tested in a case study consisting of intra- and inter-dependent electricity, coal, oil, and gas infrastructure in the state of Connecticut. © 2019 American Society of Civil Engineers. |
