A Satisficing Game Theoretic Approach to Multi-Aircraft Collision Avoidance

摘要

We propose a distributed approach to multi-aircraft real-time conflict resolution based on satisficing game theory which considers reducing flight collisions and improving economic efficiency.In our conflict game model,aircraft as exclusively self-interested agent are assigned different statuses by a priority ranking mechanism proposed.According to the state of one's own priority,they take others’preferences into consideration to choose the most satisficing conflict resolution strategy from policy set including speed and heading modification strategies.The simulation results on the random flight scenario of two concentric circles show that our method which adopts speed and heading adjustment to avoid conflicts is promising in terms of safety and system efficiency.
