飞行计划集中处理的流量瓶颈点的识别与优化

Identification and Optimization of Flow Bottlenecks on Centralized Flight Plan Processing

为建设全国级的空中交通流量管理系统提供智力支持,将飞行计划集中处理这一手段,运用于预战术飞行流量管理阶段的流量管理方法和技术的研究之中,提供了一条新的研究思路。首先,利用过点时间预测算法计算过点时间,并根据过点时间统计出关键航路点的流量预测值;接下来,通过航路点容量模型识别航路上飞行流量大于容量的航路点,即流量瓶颈点;然后,通过多机场地面等待模型并利用各种流量管理手段来减少瓶颈点的飞行流量,消除飞行流量瓶颈点,最终达到缓解空域拥堵、减少飞行冲突的目的;最后,通过算例仿真的结果可以发现:流量预测方法能够反映流量变化的趋势,瓶颈点识别与优化方法能够当容量限制时很好的缓解航路拥挤,同时此两种方法都是切实可行和有效的。

To provide intellectual support for the construction of national air traffic flow management system in China,the means of centralized processing of flight plan was applied in the research of related flow management methods and technologies in the pre-tactical flight flow management stage to provide a new research idea for the research of air traffic flow management.Firstly,the passing time was calculated by the passing time prediction algorithm,and the flow forecast value of the critical waypoint was calculated.Secondly,the waypoint capacity model was used to identify the en-route flow bottlenecks where the flight flow is greater than the capacity.Thirdly,the multi-airport ground waiting model and various flow management methods were used to reduce the flight flow at the bottleneck point and eliminate the flight flow bottleneck point,so as to achieve the goal of alleviating airspace congestion and reducing flight conflicts.Finally,through the simulation results of the example,it can find that the method of flow prediction can reflect the trend of flow change,and the method of identification and optimization of en-route flow bottlenecks can well alleviate the traffic congestion when the capacity is limited.At the same time,the two methods are feasible and effective.
