空中交通管制扇区划分是应对终端区空域需求增长的重要手段。根据终端空域内交通流特征,提出终端区内扇功能性的概念。对基于计算几何和遗传算法的两阶段划分方法进行了研究,以终端区空域图模型为基础,利用改进的切轮法(Wheel-cut)得到内扇初始边界。综合考虑内外扇区管制员平均工作负荷均衡以及高峰小时交通流分配问题,利用遗传算法对内扇边界进行优化。通过大连终端区进行实例分析证明,方法能够得到理想的内外扇区划分结果,算法耗时6.5 s。
空中交通管製扇區劃分是應對終耑區空域需求增長的重要手段。根據終耑空域內交通流特徵,提齣終耑區內扇功能性的概唸。對基于計算幾何和遺傳算法的兩階段劃分方法進行瞭研究,以終耑區空域圖模型為基礎,利用改進的切輪法(Wheel-cut)得到內扇初始邊界。綜閤攷慮內外扇區管製員平均工作負荷均衡以及高峰小時交通流分配問題,利用遺傳算法對內扇邊界進行優化。通過大連終耑區進行實例分析證明,方法能夠得到理想的內外扇區劃分結果,算法耗時6.5 s。

Airspace sector partition is proved to be a significant method to address gradually growing de-mand of airspace ,especially in terminal airspace .According to the characteristics of traffic flows in termi-nal airspace ,a concept of functionality of internal sector is proposed .A two-stage method which based on computational geometry and genetic algorithm ( GA) is investigated .Based on the terminal airspace graph model which built first ,an improved wheel-cut method is proposed for initial partition .Then,to balance controllers′average workload between internal and external sectors and to distribute traffic flows at traffic peak hours ,GA is used to optimize the initial boundary of internal sector .Dalian terminal airspace is pres-ented as an example ,and the experiment shows a promising partition result .Time cost of the optimization algorithm is 6.5 s.
