摘要
跑道作为机场飞行区与终端区的衔接部分,因容流失衡频繁引发空中交通拥堵及航班延误等问题。为提高多跑道系统运行能力,针对相关进近跑道运行模式,研究了多跑道时空资源优化调度方法。通过深入剖析多跑道时空运行特性,综合考虑移交间隔、尾流间隔、纵向间隔和相关斜距等约束限制,科学权衡安全、经济和环境等各方利益需求,建立了相关进近模式下多跑道时空资源优化调度模型。结合多目标优化及遗传算法基本理论,设计了带精英策略的非支配排序遗传算法,对模型进行了准确求解。仿真实验表明,模型可对相关进近航班进行优化配置,有效降低航班延误时间和航空发动机污染物排放量。与随机和交替调度策略相比,优化调度策略执行效果显著,其中航班延误时间分别减少了39.3%和32.6%,所提方法可显著缓解大型繁忙机场航班延误情况,有效提高航班正常率,并完全适用于独立进近模式。
As the convergence part of the airfield and terminal area at an airport system,the runway causes frequent air traffic congestions and flight delays due to the unbalanced demand and capacity.In this work,an optimized method for multirunway spatio-temporal resource scheduling in the mode of dependent approaches is proposed to improve the service ability of multi-runway systems.By analyzing in depth the spatio-temporal characteristics of multi-runway systems and taking into considerations the control handoff separation,wake turbulence separation,longitudinal separation,and slope separation,an optimized model is established to balance different factors of interest such as safety,economy and environment.Then an elitist non-dominated genetic sorting algorithm is designed in combination with the multi-objective optimization theory,and applied to solve the problem of multi-runway scheduling.Simulation results show that the above model and algorithm can achieve optimized scheduling for aircraft in dependent approaches,and it can effectively reduce flight delays as well as pollutant discharges of aeronautical engines.Compared with the random and alternate scheduling strategy of multi-runway,the optimized model brings about a striking effect of 39.3％ and 32.6％ reduction in flight delays.The method which is entirely applicable to the mode of independent approaches can significantly relieve the flight delays at large busy airports,and effectively improve the flight punctuality rate.
