多元受限下离场时间多目标优化调配模型研究

在空中交通受到多元限制情况下,对航班离场时间的优化调配可以解决空域拥挤,减少航班总体延误成本。采用了基于航班流的公平性指标和基于个体航班延误成本的效率指标作为模型的优化目标,建立了离场时间多目标优化调配模型。通过仿真算例对比了只考虑效率目标的离场时间单目标优化调配模型和同时考虑效率和公平性目标的离场时间多目标优化调配模型,验证了离场时间多目标优化调配模型的有效性。

Research on Departure Time Multi-objective Optimized Allocation Model under Multi-unit Capacity Restriction

When air traffic is under the multi-unit capacity restriction ,the flight departure time optimized allocation can solve the airspace congestion and reduce the total flight delay cost .A Fairness metric based on the traffic flow and an efficiency metric based on the flight delay cost are adopted as the optimization objectives .A departure time multi-objective optimized allocation model is then established .The efficiency single objective model is compared with the multi-objective model which considered both efficiency and fairness objective through simulation example .The efficiency of the departure time multi-objective opti-mized allocation model is validated .
