Research On Technologies Of The Conflict Detection And Resolution For Future Air Traffic Management

With the rapid development of China's civil aviation and ever-growing air traffic flow, free flight tends to solve the problem of lateral flight in the future. Conflicts detection and resolution under the circumstance of free flight will be a key technology which will guarantee the flight safety and the improvement of benefits.In the first part of this paper, the author fully studies all the existing methods of conflict detection and resolution and establishes a simplified model of free flight after the analysis of the cost of conflict resolution. Then, according to the advantages of Genetic algorithm's robustness and parallelismand and to the characteristics of Game therory's equilibrium strategy, the author, from a perception of cutting down the cost, respectively uses the basic genetic algorithm and a combination of genetic algorithm and Game therory to study the conflict resolution and finds that both can solve the problem under the circumstances of free flight. In the last part, the author makes an analysis and a comparison of the two methods. The emulative results shows that, when compare the basic genetic algorithm with the combination of genetic algorithm and Game therory, the conflict resolution of the former has a better result of quality and efficiency. Based on the premise of the flight safety, it will have a vaster vista if the method of the combination of genetic algorithm and Game therory is used in order to obtain a balance of the benefits of every plane.
