多机场终端区进离场航班协同排序研究

为了缓解繁忙终端区日益严重的空域拥堵和航班延误现状,研究了多机场终端区进离场航班协同优化排序问题.通过深入分析多机场终端空域结构,以及进离场航班运行特征,综合考虑尾流间隔、移交间隔、放行间隔、多跑道不同运行模式下的运行间隔等约束限制,将多机场终端区视为一个系统,引入"外围航班流"概念,以最小化航班延误为优化目标,建立了多机场终端区进离场航班协同优化排序模型,并采用改进的模拟退火算法对所建模型求解.选取上海终端区为研究对象进行仿真验证,仿真结果表明:利用本文提出的优化方法航班总延误比先到先服务策略减少了37.85%,有效地提高了多机场终端区进离场航班的运行效率.

Collaborative Arrival and Departure Sequencing for Multi-airport Terminal Area

This paper investigates the collaborative arrival and departure sequencing problem for multiairport terminal area to alleviate the ever- increasing serious airspace congestion and flight delay. To begin with, the multi-airport terminal area is viewed as an entire system through in-depth analysis of the airspace structure and the characteristics of arrivals and departures. Then all kinds of constraints are taken into account, such as wake votex separation, transfer separation, release separation, and operational separation in different modes of multiple runway. Furthermore, "outside traffic flow" concept is proposed, based on which the collaborative arrival and departure sequencing model is constructed for multi- airport terminal area by minimizing the total delay. In addition, the improved simulated annealing algorithm is presented to find the optimum solution. Finally, Shanghai multi- airport terminal area is chosen to conduct the simulation. The simulation results indicate that the proposed method in this paper is able to reduce the total delay by 37.85 % in comparison to first-come-first-served (FCFS) strategy. The conclusion could be drawn that the proposed method is able to effectively improve the operation efficiency of arrivals and departures in multi- airport terminal area.
