Gate-to-Gate模式下航班到达的综合调度

Synthesized Scheduling of Aircraft Arrival under Gate-to-Gate Mode

Gate-to-Gate是空中交通管理的未来趋势之一,研究了Gate-to-Gate模式下的航班到达问题,对航班到达的空中降落与地面滑行进行综合调度,建立了地空综合调度的简化数学模型,实现了航班到达从区调阶段到航站楼的关键点路径规划和时间安排,并对北京终端区及首都机场地面滑行过程进行了算例分析。针对实际应用规模大、求解时间长的问题,利用模型的特殊性制定了先松弛后固定分支求解的两步法求解算法,实现了在5分钟内能求得相对误差小于5.3%的近优解。

Gate-to-Gate is one of the future trends of air traffic management. Aircraft arrival problem is investigated under the Gate-to-Gate mode. We carry out a synthesized scheduling for both aircraft arrival’s airborne flight phase and ground taxiing phase, building a simplified mathematical model for integrated air-ground scheduling, which assigns key routes and time from the Area Control stage to the gate. An simulation example is carried out based on Beijing Terminal Area and Capital International Airport. A two-step relax-and-branch algorithm is created to handle the difficulty of long solving time of practical large-scaled model, which gives near-optimal solutions with 5.3% relative gap within 5 minutes.
