离场航空器优化排序是加速终端空域内航班流动、提高航班正点率、缓解管制工作负荷的有效手段。采用滚动时域控制(Receding horizon control,RHC)策略构建离场航空器实时动态排序框架,并基于分支定界法获取时间窗内优化的目标起飞时间。在此基础上,利用修正的离场滑行时间确定允许开车时间,从而为管制员提供决策支持。以上海浦东机场离场运行为例进行仿真验证,结果表明文中提出的方法不仅有效地实现了管制决策支持(为管制员提供目标起飞时间与允许开车时间),也能够提升跑道离场容量,降低离场延误水平。
Departure sequencing is an effective means to expedite terminal air traffic flow, improve depar- ture punctuality and alleviate controllers' workload. The framework for dynamic sequencing is built based on receding horizon control (RHC) strategy. And through the branch and bound algorithm, tar- get takeoff time (TTOT) is optimized within the sequencing window. Furthermore, target start-up ap- proval time (TSAT) is obtained depending on the amendment of taxi out time so as to provide the deci- sion support for tower controller. Taking ZSPD airport as an example for simulation, the result indi- cates that the proposed algorithm can realize decision support for controllers (providing TTOT TSAT), enhance the runway departure capacity, and reduce the departure delay.
