基于两次应用优先级的GDP时隙分配算法模型

摘要

地面等待策略是空中交通流量管理中主要采用的一种方法，文中主要介绍了基于两次应用优先级的GDP时隙分配算法。初次优先级的使用是达到分组的目的，再次应用优先级则是为了解决初次分配后可能存在的在同一分组中航班竞争同一时隙的问题。文中对相应的算法实现做了详细介绍，并对成都双流机场的航班进行了多次仿真实验。同时和单纯的基于优先级的方法进行了对比，验证了该算法的可行性。%The ground-holding strategy is one of the main methods in air traffic flow management. The GDP time-slots distributed algo-rithm based on two times adopting priority is proposed. The first time of the calculating of the priority of the airplane is mean to classify the flights;the second time aims to resolve the problem of the competition of the flights in the same group to dispute the same time-slot. In this paper,give the detailed account of the algorithm, and give the simulation results according to airplanes in Shuangliu airport of Chengdu. At the same time,compared with the algorithm only based on priority's result,shows that the algorithm is practical.
