| 摘 要： | 为实现对航空器飞行冲突调配策略的自动搜索和优化,首先对飞行冲突的探测方法、冲突类型及解决策略进行了分析。利用A*算法构造了策略选择模型,为减少搜索空间,设定了以管制员工作负荷最小为优化目标的估价函数。北京区域管制中心02扇扇区TZH导航台附近的航路仿真算例表明了该方法的可行性,为管制员的指挥提供了科学的决策支持。

| Abstract: | For searching and optimizing the resolution strategy against aircraft flight conflicts automatically, the detection as well as the type and disposal of conflicts are analyzed firstly. A strategy selecting model is constructed using A* Algorithm for decreasing the searching space and a cost function aiming at minimizing the working load of ATC controller is designed. A flight conflict example supposed at TZH beacon in 02 sector of Beijing Area Control Center indicates the feasibility of the method, which provides a scientific support for decision-making of the ATC controller. |
