空中交通短期流量管理的动态网络流模型

Dynamic network flow model for short-term air traffic flow management

针对优化调度空中交通短期流量的迫切需求 ,研究空中交通管制区的网络结构和确定容量条件下空中交通流的动态行为 ,给出了空中交通短期流量管理的多品种动态网络流模型的数学描述 (ST- TFMP) ;并就管制区内现有飞机的疏散问题对原模型进行了改进。利用北京管制区某日高峰飞行时段的到达流量实际数据 ,在不同场景下对模型进行了仿真验证 。

This paper first analyzes the embedded network structure of local airspace and the dynamic behavior of air traffic flow, and then presents a mathematical model, STTFMP, for shortterm air traffic flow management based on multicommodity dynamic network flow. An improved model STTFMP1 is also discussed which can describe evacuation behavior of traffic flows existing in local airspace when flow control starts. The STTFMP model is verified by real operational data from the Beijing Regional ATC Center of CAAC. The computational results show that the model is feasible.
