Knowledge modelling and multi-agent simulation: application to flood risks

This article proposes a multi-agent approach to manage the agrarian, economic and hydrologic knowledge of an agricultural territory. The knowledge is distributed over groups of agents in conflict in an environment. The problem resolution environment consists of the different parcels to occupy, characterized by size, slope, sensitivity etc. A group of agents is associated to each type of culture. From an initial occupation of the ground, the agents seek possibilities of permutation among the parcels of the territory in order to minimize the flood risks without degrading the individual satisfactions of their groups. We present the results obtained on the watershed of Villers-Ecalles (Pays de Caux, France).
