Abstract
Abstract This paper deals with the decision making in data fusion process. The application domain is the “Intelligent Vehicles”, where the information coming from the perceptive system must have a good level of reliability in order to perform the mission. The decision making comes when we must decide if a relation is true or not. This decision leads to an action on the fusion process, the perceptive system or directly on the vehicle. Generally, a relation links two objects, a comparison is made between their attributes. Usually, only the numerical attributes are used, in order to compute a “distance” between the objects. We suggest to use all the types of attributes, the numerical ones, of course, but also the symbolic and the logical ones. For each type of attributes, we define a distribution of mass which corresponds to the opinion of an expert. Then, all the opinions are combined using the Dempster’s relation, in order to quantify the belief we can have on each relation.
