ABSTRACT
In French legal framework, Mayors must alert population on their territory about threats and dangerous events such as natural, technological and transport risks. Mayors should inform and ensure population safety. Since 2004 Safeguard Plan (Plan Communal de Sauvegarde) has to be set up by Town Administration, where threats on territory are indexed and the way to handle them are described. Safeguard Plan is an organizational decision making tool. A safeguard plan is a particular Emergency Response Plan (ERP) owned by Local Emergency Response Plan (LERP) category.
This work deals with organizational plan evaluation in which population safety is at stakes. Local Emergency Response Plan assessment stand up to following questions:
Do human and technical resources are available, good enough and correctly quantified?
Do protagonists are able to give an answer with the current means and information?
Does planned answer is appropriated? assessment is possible via model-based analysis. development.
Previous work (Karagiannis et al. 2010) deal with robustness assessment of industrial response plan and proposed a method to assess probability of failure in the Safeguard Plan. But this method does not allow verifying that the proposed overall plan matches its purpose. Based on a modeling method, this
This paper will present a new application of modeling method used for industrial plan to safeguard plan to answer previous questions. It is proposed a systematic approach to analyze LERP based on a meta-model with taxonomy of elements engaged in the plan. This meta-model is applicable for every town needing a safeguard plan. With the meta-model structure for LERP, it is possible to visualize all interactions between model elements and to analyze the realization of the plan.
The described approach takes into account dysfunctioning modes in combination to functional behavior to verify the adequacy of the plan. To do that, six indicators describing the plan resources state have been identified for each element of the Safeguard Plan: Availability, Capacity, Autonomy, Adequacy, Quality and Set up. These elementary indicators are structured by adapted Fault Trees to follow the plan development.
