基于改进的单服务台混合制模型的终端区飞行效率研究①

摘要

随着我国枢纽机场交通流量的增加，终端区飞行效率的优化问题日益凸显。该文首先建立随机的模拟飞机流，采用实际运行中通过各个航路点的飞机流比率、机型混合比率等统计数据，利用改进的单服务台混合制模型（M/M/1/K），对基于性能导航（Performance Based Navigation PBN）飞行程序与传统飞行程序的终端区飞行效率进行对比。结果显示，基于性能导航飞行程序的终端区飞行效率明显高于传统进场程序，改进的单服务台混合制模型为研究终端区飞行效率提供了有效的方法。%With the increase in traffic flow of hub airports, the optimization problems of flight efficiency at terminal area have become increasingly prominent.The paper establishs stochastic simulation aircraft flow at first,then use the ratio of aircraft flow at each waypoint,mixing ratio of aircraft type and other statistical data, utilize the improved M/M/1/K model compare the flight efficiency of performance based navigatin(PBN) flight procedure with traditional flight procedure. The results show, the flight efficiency of performance based navigatin flight procedure Significantly higher than the traditional flight procedure,the improved M/M/1/K model provides a efficient method to research the flight efficiency at terminal area.
