A Resource Allocation Model for Improving the Resilience of Critical Transportation Systems July 1 , 2014

The functioning of society and economy depends on critical infrastructures which are vulnerable to disruptions: energy distribution networks and water supply systems, for example, can be exposed to power outages and supply chain disturbances. Analyses of these vulnerabilities are therefore needed to assess and secure the performance of critical infrastructures. Towards this end, we model critical transportation systems as networks which consist of nodes and edges and whose performance is measured by the extent to which the transportation objectives are achieved even if part of the network may be disrupted. Specifically, we develop decision analytic methods to determine (i) how different combinations of disruptions would impact the performance of the network and (ii) which combinations of risk management actions are cost-efficient in maintaining the performance of the network at as high a level as possible with regard to multiple evaluation criteria.
