Modèle décisionnel orienté comportement fondé sur le vote : Application à la navigation d'agents autonomes en environnement simulé

Abstract : Autonomous virtual actors are agents that move in dynamic and continuous environments. They must decide in real time in order to adapt themselves to their environment. That is why they have to include efficient decisional model. The behavior based decisional models are well suited to this kind of problems. They are based on the assumption that a decision making process can be shared among several entities, called behaviors. The main difficulty of its approach is to select a global decision from the propositions suggested by the behaviors. Within this context, the vote have got many advantages. However, it does not allow to select action in a continuous set and uses weights that bias the selection. Our contribution consists in a modification of the behavior coordination voting method. Our proposition allows to select action in a continuous set, to use finely grained behavior and it proceed to the vote in a different way. We applied the decisional model to the reactive autonomous navigation in virtual environments. The tests give proof of the model interest and don't uses any weights. The results in static environment shows that the decisional model is able to achieve a goal while tacking in account the constraints and persisting in its choices. The results in dynamics environments decrease when the number of agents are higher as twenty. The action selection problem is open. So, this work will have several future work, practical ones (simulation of couple or groups of agents) and theoretical ones (linking with a more abstract reasoning module).
