Abstract :
This paper describes INFUSION, a system for the evaluation of situations and threats in simulated military scenarios and for scenario projection, in order to support the decision making process in strategic and tactical context. The system deals with fuzzy variables that model information acquired from the on-going scenario; it adopts the Evidence Theory approach to fuse information and classify situations; moreover, it evaluates threats measuring the risk of on-going situations on the items of interest. INFUSION is able to foresee possible future scenarios, through the projection of the item of the simulated scenario to a desired time or position. Trajectory projection of items depends on their intent, estimated through the Bayesian approach. INFUSION has been tested on different terrestrial scenarios where the situations of encirclement, collision and engagement have been simulated. Considerations on operative results and future works are also reported.
