A Collision Avoidance Method Based on Satisfying Game Theory

Flight safety at both high and low altitude airspace become more and more important in the recent years. In this paper, considering the free flight characteristic of aircrafts in airspace, a decentralized approach based on satisficing game theory is proposed. This method can eliminate conflicts among aircrafts effectively, and it can also solve collisions with obstacles which mainly include the special use airspace (SUA), severe weather regions in high altitude airspace, and obstacles in low altitude airspace. The simulations show good performance in a complex scenario, which includes a large number of aircrafts flying through a airspace with obstacles at the same time.
