摘要：

The paper describes a new integrated formalism for the dynamic functional modelling of vulnerability and interoperability of Critical Infrastructures at regional level. The model assesses the propagation of impacts in terms of disservice due to a wide set of threats. The disservice can be propagated within the same infrastructure or to other CIs by means of the interdependence model, which is able to represent physical, cybernetic, geographic as well as logical interdependencies and also the shift of the demand between two infrastructures that can provide the same or fully/partially replaceable service. The model is dynamic, since both the impact of the specific threat on a generic infrastructure node and the inoperability functions are time-dependent. A pilot study has been carried in the metropolitan area of the province of Milan, considering the Critical Infrastructures referred to the transportation system. (C) 2011 Elsevier Ltd.
