Une analyse formelle du jeu des acteurs autour du projet de barrage de Sivens

Abstract : The French public was stunned by the death of an opponent to the construction of a dam in the Sivens forest (southwestern France) during confrontations with the police on the night of 25 to 26 October 2014. Yet the considerable means deployed to carry out this project and the determination of opponents, embedded in the interactions between all the stakeholders of this project, foreshadowed the possibility of this exceptional drama. We have used a formal analysis framework based on the sociology of organized action to present a model of this interaction system: the main actors, their respective means of action and their dependence on each other to reach their objectives. The structural analysis of this model highlights the position of each actor and the main conflicts between them. A bounded rationality algorithm, which measures how each actor learns to develop a behavior that enables him/her to reach their objectives in the best possible way according to the behavior of others, allows to make simulations whose results show the overdetermined emergence of a clash of extreme intensity. Variations in this model then make it possible to identify the main determinants of this conflict and to consider another possible future
