Extension of DMCI to heterogeneous infrastructures: model and pilot application

ince the adequate functioning of critical infrastructures is crucially sustaining societal and economic development, the understanding and assessment of their vulnerability and interdependency become more and more important for improving resilience at system level. The paper proposes an extension of DMCI (Dynamic Functional Modelling of vulnerability and interoperability of CIs) to modelling the vulnerability and interdependencies of heterogeneous infrastructures, i.e. the interactions between electric power infrastructure and the transport infrastructure system have been modelled. The simulation tool has been implemented with the Matlab platform Simulink in order to overcome some computational limitations, that affect the first DMCI version implemented in Matlab, in quantifying the propagation of inoperability and logical interdependencies related to demand shift, and to obtain a modular and user friendly solution, even for users who are not expert at simulation. The new DMCI model has been tested with a pilot application that comprised more than 200 vulnerable nodes and covered both power transmission grid and transportation systems of the province of Milan (Italy). The most vital and vulnerable nodes have been identified under different blackout scenarios, for which specific data on vulnerable nodes has been collected directly from the operators.
