Abstract
Designing decision, control and information systems is motivated, .in part, by the need to support the deployment of multiple aircraft, such as combat vehicles, UCAVs, UAVs and weapons, in missions taking place in a dynamic, although uncertain, environment. Such systems aim at ensuring mission success without overloading the operating crew, the pilots and the commanders. One of the main design challenges lies in obtaining some sort of coherent behavior of the fleet, by means of solutions to potentially NP-hard problems, given incomplete and imperfect information, and despite limited computational• and communication capabilities. In this context, this paper proposes a hierarchical decision and information system aiming at providing, in real-time, coordinated aircraft path planning and deceptive engagement assignments. The blue-red engagement policy is obtained by minimizing, and balancing, the energy expenditure among the vehicles while constraining information exchanges to a minimum defined by a risk of inconsistency. The proposed system relies on dynamic programming, online heuristic techniques and stochastic, consistency-checking methods. Numerical simulations show that the proposed approach compares advantageously to a random process and to a law that seeks to minimize the cost of the confrontation at a given time regardless of past moves. However, there is a trade-off between increasing the level of deception and the level of energy consumption..
