Abstrakt: Critical Infrastructure System (CIS) disruption cascades into all the dependent CISs, even the regions, over the internal system where the disruption occurs. This study develops a cascading impact analysis with a region-based path-flow estimation approach based on a complex network and provides a local-scale demonstration of the interdependent electric power-water supply system in Incheon, South Korea. The analytical framework facilitates the modeling of CISs considering three major structural relationships – CIS, CIS-CIS, and CIS-Region- with functional interdependency and quantifying cascading impacts on regions via a continuous service flow. The results demonstrate more practical cascading ranges and levels caused by each CIS disruption, highlighting that the potential impacts increase in an integrated network, which a single CIS network cannot capture. It emphasizes the need to consider functional interdependent CIS structures and estimate cascading impacts from a regional perspective. This study provides multiangle insights into how regions enhance resilience through infrastructure disaster management. [ABSTRACT FROM AUTHOR]
