考虑空域功能性的终端区内三维扇区划设方法研究

为缓解终端区内管制扇区划设不合理的问题，本文结合空域功能性研究了终端区内三维扇区划设问题。首先，在满足传统扇区约束条件的前提下，以降低所有扇区管制负荷之和与均匀各扇区管制负荷为目标。接着，结合垂直高度的层次聚类与水平方向的泰森多边形划分，将终端区划分为若干个三维空域单元并根据不同的飞行性质赋予各空域单元不同的功能属性。根据优化目标，考虑功能性的相近程度，采用NSGA-II算法将各三维空域单元组合形成扇区。最后，以上海终端区为实例进行验证。结果表明，相比于现行扇区划设方案，优化后的扇区划设方案能够有效地降低扇区的管制负荷之和，同时均匀各扇区的管制负荷。

Research on Three-dimensional Sectorization in Terminal Area Considering Airspace Function

In order to alleviate the unreasonable sectorization in the terminal area, this paper studies the three-dimensional sectorization problem considering airspace function. Firstly, the objective of this paper is to reduce the workload of all sectors and to reduce the standard deviation of workload of different sectors on the premise of meeting the constraints of traditional sectorization. Then, combining the hierarchical clustering of vertical height and the horizontal segmentation of Voronoi diagram, the terminal area is divided into several three-dimensional cells and each cell is assigned a specific function by different types of flights. According to the optimization objective and considering the similarity of function, NSGA-II algorithm is used to combine all cells to group sectors. Finally, Shanghai terminal area is taken as an example to verify. The results show that compared with the current sectorization, the optimized sectorization can effectively reduce the workload of all sectors, and at the same time equalize the workload of different sectors.
