Analyse multi-échelle de la vulnérabilité des réseaux des systèmes territoriaux

Abstract : In this work, we deal with risk prevention and crisis management requiring evacuation. Road network structure and mobility process are studied by using swarm intelligence methods. Risk prevention is considered by analyzing the vulnerability of the network represented by a multigraph, at different scale levels thanks to betweenness centrality and hierarchical clustering methods. Crisis management during an evacuation is also treated. A microscopic traffic model is developed and a micro-evacuation simulator is proposed to organize an evacuation, beginning from crisis occurrence until vehicles evacuation. Our model is adaptive, it takes into consideration multigraph structure and its elements vulnerability at different scale levels, and unexpected events during an evacuation. Finally, the developed tool helps decision makers managing risks.
