Disaster Consequence Analysis on Blackout considering Interdependency Matrix and Resilience in Critical Infrastructure

Critical Infrastructure (CI) needs individual unit management and interdependency-based management because of their importance. So each CI is exquisitely and systematically managed under the related laws and regulations in terms of individual unit. But it is deficient to manage CI on the basis of Interdependency. Although "Disaster and Safety Management Fundamental Act" requires that CI is designated and managed in the light of cascade effect, coordinated response and individual unit, CI is primarily evaluated and protection plan is drawn-up by individual unit up to now. Thus this research suggested connectivity analysis methodology and drew up interdependency matrix through overseas case study. Furthermore this research analyzed disaster consequence on the basis of CI interdependency with consideration for blackout case and found out that interdependency matrix is useful to analyze relation among CI.
