为解决高峰小时场面航空器滑行冲突,提高机场运行安全和效率,减少航班延误损失,提出了基于航班优先级的航空器滑行调度模型。以基于最短路径的总调度时间最小为目标,使用滚动时域策略,设计预测窗口、滚动窗口、调度子问题、滚动机制等调度要素求解模型。仿真算例表明,此调度模型能够在兼顾航班优先级别属性的同时,规避了滑行中的各类冲突,对枢纽机场高峰小时内的18架不同属性的航空器实施了优化调度,较之原调度方案,总体时间减少了近2min,提高了总体效率。
In order to solve the conflict of aircraft taxiing in peak hours, improve the safety and efficiency of airport operation and reduce the flight delay loss, a taxi scheduling model based on flight priority is proposed. In order to minimize the total scheduling time based on the shortest path, we use rolling time domain strategy, design prediction window, rolling window, scheduling sub-problem, rolling mechanism and other scheduling elements to solve the model. The simulation results show that this scheduling model can avoid all kinds of conflicts in taxiing while taking into account the flight priority attributes and implement optimal scheduling for 18 aircraft with different attributes in the peak hour of the hub airport. Compared with the original scheduling scheme , The overall time reduced by nearly 2min, improve the overall efficiency.
