Decision Support System for Infrastructure Networks Vulnerability to Natural Disaster
Résumé
In a high industrialization context, our societies depend more and more on networks such as power grid, water, gas and telecommunications systems. The number and the variety of events such as snowfall in Paris in winter 2010, or the tsunami in Japan in March 2011 demonstrated the infrastructures’ vulnerability against natural disasters. In addition the various materials, services, energies and information exchanged may aggravate or mitigate the consequences. Because of the interdependencies, the malfunction of a network’s entity is likely to spread to the others; to a scale exceeding one of a country, making difficult any risk analysis. The VESTA project aims to propose a methodology of analysing infrastructure network risk and vulnerability in the field of prevention or reduction of the natural disaster consequences. This model will lead to a decision support system multi-view, multi-stakeholder, and communication’s protocols in crisis situation.
