摘要
为确定规划扇区数目,提高扇区规划方案的灵活性,提出了基于变精度粗集的动态扇区数规划方法.该方法根据空域航班飞行数据,用可变精度粗糙集理论,获取不同航班数量条件下规划扇区数目的规则,约束条件为根据管制员工作负荷确定的扇区容量和相邻时段扇区规划数量的连续性.实例分析结果表明,用该方法使空域扇区数量随不同时段交通流量的变化,实现了扇区数量动态规划.
To precisely estimate sector number and improve the flexibility of sector plans, a dynamic sector plan method based on variable precision rough set theory was proposed. In the method, the rules for a sector plan of different flight numbers are derived from the existing flight data and based on the variable precision rough set theory, and constraints are sector capacities determined by the controller＇s workload, and the number continuity between adjacent sectors. The method was applied to a practical case. The results indicate that the airspace sector number varies with the air traffic flow in different period of a day, and that the method is valid to achieve dynamic airspace sector plans.
