| Summary: | Critical infrastructures like electric power plants, oil and gas supply, telecommunication, and the internet are essential systems for the continuous functioning of modern society. They are highly interconnected networks that are highly interdependent and any failure can cascade through the network, escalating to devastating impact on the economy. In this study, a combination of input-output (I/O) model and network analysis will be used for analyzing the vulnerabilities in critical infrastructure networks. The objective is to show how the critical infrastructure interdependencies model can be applied to disruptions/failures in two or more critical infrastructures and to evaluate the resulting impact on a country based on linkages established from its economic input-output table. The worst case scenario of a possible catastrophic event can therefore be simulated using this model. The methodology demonstrates how partial failure of two or more critical infrastructures contributes to higher overall impact on an economy and may provide useful insights for infrastructure stakeholders and policymakers. |
