一种新的机场地面容量评估模型

空中交通流量剧增，机场容量与空中交通需求的矛盾日益凸出，针对机场地面滑行网络，提出滑行飞机流优化算法，确定飞机经过指定滑行路径上各点的最优时间，避免航班冲突，减少航班延误，将该算法用于机场地面容量评估模型中的飞机流产生模块，结合计算机图形仿真技术开发了机场地面容量评估系统，利用成都双流国际机场的实际航班数据进行仿真计算，得到的容量评估结果验证了该评估模型的可行性和优越性。

Research on a New Capacity Evaluation Model of Airport Ground

The dramatic increase of air trafficflowinducestheseverecontradictionbetween the airport capacity and air traffic demand. In compliance with the complicated airport ground taxiway network, an optimization algorithm of taxiway traffic flow was put forward to determine the optimal time for every aircraft passing its assigned taxiway. Adopting the algorithm as a module to generate optimized traffic flow and combining with the computer geographic simulation technology, an airport ground capacity evaluation system was developed. Taking the practical flight schedule of Chengdu Shuangliu International Airport as a calculation example, the obtained numerical results verified the feasibility and superiority of the model.
