Diagnostic des Dysfonctionnements des Plans de Secours pour la Gestion des Risques Majeurs

Abstract : The increase in frequency and intensity of major disasters make a consensus. In France, the state imposes to local administrations to be prepared to face such events by describing their local organizations in a Local Emergency Response Plan (LERP). However, there are no existing tools for decision-Makers at this authority scale to a priori assess functioning capacity of the organization described in their plans. This research work proposes an a priori assessment method of Local Emergency Response Plans, to allow local authorities to identify organizational vulnerabilities of their plans, and thus giving to them an aid to decision-Making. This assessment method is laid on an established formalism of modelling methods. This allows, in one hand, to catch the complexity of elements’ stakes in emergency management and in another hand to lay assessment mechanisms for this one. These mechanisms are supported by Fault-Tree formalism. However, this is restricting because the failure of modelled elements can only be assessed on two discrete levels: complete functioning or complete dysfunctioning. This is why this work aims to build an assessment method based on Multi-Level Fault-Tree. This means that new gates have to be described according to the assessed object (LERP). Furthermore, modelled elements have to be improved to take into account Multi-Level considerations in the chosen modelling method. According to that, a questionnaire has been developed to collect information from local authorities about failure states of modelled elements. The results of this assessment are presented in a dashboard format. The purpose is first, to guide local authorities by having a quick overview of the overall organization system represented in the LERP. Secondly, it helps them to plan the vulnerabilities reductions in a management program.
