多跑道机场离场航班推出时刻的优化研究

摘要

According to those problems caused the airport surface congestion and flight delays, the optimization problem of launch time on the sequencing of departure flights of a multi-runway airport was studied. Meanwhile, aimed to ease the situation of the airport surface congestion, reduce the waiting time of aircraft and improve the efficiency of runway operation, in view of the aircraft wake separation and runway capacity, a launch time model of departure flights on a multi-runway airport was built, and a heuristic algorithm was adopted to solve the problems. An example to verify the true or false of the model was taken. Results showed that,compared with the first come first service launch method, after simulation of this model, the total waiting time of flights reduced by nearly 41%, the runway utilization ratio increased by 30% at the same time.%针对繁忙机场场面拥挤造成的大量航班延误状况，作者研究了繁忙多跑道机场离场航班的推出时刻最优问题，以缓解机场场面拥挤，减少航班的地面等待时间和提高跑道利用率。根据飞机尾流间隔的要求以及跑道起飞容量的限制，本文建立了多跑道机场离场航班推出时刻模型，并针对机场小规模的离场航班流量，设计启发式算法，并用算例进行仿真验证。结果表明，与先到先服务的推出时刻策略相比，经该算法优化后的航班总地面等待时间减少了近41%，同时跑道利用率提高了30%。
