Abstract:

Multi-objective rerouting path planning method is put forward to solve multi-aircraft disturbance caused by severe weather. Rerouting environment based on gird is built at first, changes of weather and aircraft maneuver are considered. Then multi-objective optimization model is proposed with fewer turn, minimum length of trajectory and minimum rerouting area as its targets. Genetic algorithm is improved to solve the model. Finally,Xi'an control area is studied to verify the method effectiveness with actual flight data. Results show that the method used to get multi-aircraft trajectory is effective to reduce delay and can meet the demands of separation.

Key words: air transportation, rerouting path planning, multi-objective optimization, multi-aircraft, dynamic severe weather
