【Abstract】 An intelligent tactical mission management system for modern combat aircraft was proposed based on the cognitive decision process of perception, assessment and decision. As the key subsystems of the mission management system, the situation assessment and mission planning were investigated emphatically. The algorithm of situation assessment based on Bayesian networks and fuzzy logic was established. The model of threat level assessment was developed, based on which, the threat level of threater was assessed using Bayesian networks. The relative importance among the threaters was inferred by fuzzy logic. A novel algorithm of tactical flight path planning in real-time was developed based on dynamic A * algorithm. The two subsystems of situation assessment and flight path planning were integrated based on fuzzy logic to adapt the dynamic situations in battlefield. The simulation results show that the proposed intelligent tactical mission management system can assess the threat situations dynamically and can adapt the changing dynamic situations timely.更多还原
