摘要
目前,国内大型机场场面结构日趋复杂,航班流量逐渐增多,航空器滑行冲突随之增多.文中提出一种基于航空器优先级的滑行冲突解决策略,在保证航空器优先级的前提下,合理解决滑行冲突,提高了场面运行的安全与效率.以最小化研究时段内所有进离场航空器滑行成本为目标,建立基于航空器优先级及滑行冲突解决策略的滑行优化模型,使用滚动时域方法求解模型.仿真算例表明,此优化模型不仅能够保障航空器的优先级,而且能为航空器提供安全高效的滑行路径.相比于基于先到先服务(FCFS)的固定路径滑行,总滑行距离减少1 400m,总等待时间减少42.2s;相比于基于理想滑行路径滑行,冲突点减少11个.该方法有效提高机场场面运行效率,增加场面容量.
At present,the ground structures of large hub airports in China are becoming more complex day by day.With the increasing flow of flights,the aircraft taxiing conflicts increase gradually.A taxiing conflict resolution strategy was put forward based on aircraft priority in this paper.On the premise of guarantee aircraft priority,this strategy resolves the taxiing conflicts reasonably and improve the safety and efficiency of airport ground operating.Aiming to minimize the operating costs of all arrivals and departures during the study period,a taxiing optimization model was established based on aircraft priority and the conflict resolution strategy.And then the model was solved by rolling horizon approach.The simulation examples show that the optimization model can not only guarantee the aircraft priority,but also provide a safe and efficient taxiing path for aircraft.Compared with the fixed taxiing path based on First Come First Serve（FCFS）,the total taxiing distance is reduced by 1400 m and the total waiting time reduced by 42.2 s.Compared with the ideal taxiing path,the conflict points are decreased by 11.This new method can greatly improve the operating efficient of airport ground and increase the ground capacity.
