到达率和飞机流结构对终端区排序的影响研究

为了找出终端区平均到达率和飞机流结构与优化排序结果之间的关系，通过选取平均到达率和飞机流结构的不同组合，再使用循环排序找出最优结果。在此基础上，分别研究和分析了平均到达率和飞机流结构对飞机流总体，重型飞机、大型飞机和小型飞机优化结果的影响程度。经过大量数据仿真和统计表明：当终端区有10架待降飞机时，与先到先服务原则相比，平均可以减小延误达30%左右；重型飞机和大型飞机的延误对平均到达率的变化较为敏感，而小型飞机则非常有限；从飞机流结构变化的角度看，随着大型飞机和小型飞机所占比例的逐渐减少，重型飞机和大型飞机延误可以得到明显的缩减，而小型飞机延误的缩减程度变化较小。研究结果可以为终端区飞机的着陆调度提供借鉴和参考，同时为进一步研究跑道容量与来流飞机的关系打下基础。

Research on Influence of Arrival Rate and Flow Composition on Terminal Area Sequencing

To discover the exact influence of the two parameters which are average arrival rate and arrival flow composition on terminal area sequencing results, the optimal landing sequence was searched in accordance with different combinations of average arrival rate and arrival flow composition. The influence of different average arrival rate and arrival flow composition on heavy, large and small plane was researched respectively. Simulation and statistics indicates that the optimal sequence can reduce the overall delay by almost 30% as compared with first come first served mode. The delay of heavy and large plane can be decreased to a large extent while small plane to a limited extent as the intensity of average arrival rate becomes weaker. When the proportion of large and small plane in arrival flow composition falls, the delay of weight and large plane will reduce dramatically, while the delay of small plane reduces little. The research can be referred by landing scheduling in terminal area. It also supplies a basis for research on relationship between runway capacity and arrival flow strength.
