Modèle d'aide à la décision pour la prévention parasismique urbaine. Une approche multi-agent de la vulnérabilité du bâti

This paper offers a decision-making tool for politics in charge of the prevention of the seismic risk of a city. The multi-agents methodology is applied to an urban area as a spatial environment. The focus is on the question of the public buildings, their maintenance and the investments which allow reducing their vulnerability. The public buildings are viewed as agents whose attributes are the quality of the construction, with a demography which makes them born, become older and eventually disappear. Their behaviour is mainly governed by public regulations. Our goal is to offer a method, which is at first experimented for schools and the city of Grenoble, but could be applied to other kinds of buildings and used in other spatial contexts.
