Optimisation models for critical infrastructure protection, rebuilding, and interdependency in the event of mass destruction

All critical infrastructures (CIs) are already very complex and it is getting more complicated as different systems are integrated with each other. For this reason, implementing a mathematical model for critical infrastructure is a rarely researched topic. In this study, we investigate an optimisation model for critical infrastructure protection, rebuilding, and damage assessment. In particular, our model can be usefully applied to a case of which critical infrastructure is widely damaged by a weapon of mass destruction or by a disaster. Moreover, we introduce a novel idea regarding the implementation of interdependency as a mathematical formulation. In order to validate our model, we test our model in the water system of Seoul, South Korea. We describe computational results and insights from various experiments as well.
