Abstract

In order to improve effectiveness of flight re-routing planning, a principle of determining optimal path based on 95-percent reliability was proposed to ensure agreement between flight effectiveness and reliability. Firstly, re-routing planning model was constructed with the target of minimizing flight time. Secondly, a planning algorithm based on Monte Carlo simulation and improved genetic algorithm was developed, which considered flight time reliability. Finally, with the air route network in a region in North China as an example, simulation experiment was conducted. The results show that with consideration to the uncertainty of travel time, the proposed algorithm has increased the time slightly from previous 603 min to 627 min, but the reliability gets much better growing from 50% to 95%, which is beneficial for improving efficiency of flight re-routing. © 2022 China Safety Science Journal.
