Various disciplines have focused on risk for many years. For a long time, risk has been analysed mainly through its dangerous component, hazard. It is only in middle of the XXth century that researchers have taken an interest in the study of the vulnerability of exposed elements. Among the multiple studies of risks, only a few of them deal with a multi-risks approach, most of them being monosectoral. However, it is necessary to consider risks in a global approach, if we want to simulate real situations in which the chances of observing “dominos effects” are high. In this research, we assume that interactions between risks of different nature can be observed. We develop a multi-risks and integrated approach to study the interactions between...
