为提高空中交通的安全性,降低管制员的工作负荷,提出在战略阶段进行4D航迹的冲突探测与解脱。通过对具体冲突结果进行分析,建立了高度层分配和起飞时刻调整相结合的4D航迹战略冲突解脱模型。采用Tabucol算法对所建立的模型进行求解,并对结果进行扰动性分析。选取某区域内一组预测航迹进行仿真实验,表明两种策略相结合的方法可以有效解决该范围内航迹冲突。同时相较于单一的解脱策略,该方法成本更低,可行性较高。
In order to improve the safety of air traffic and reduce the workload of controllers, it is proposed to detect and release the collision of 4D tracks during the strategic phase. Through the analysis of the specific conflict results, a 4D conflict resolution model was established based on the combination of altitude distribution and takeoff time adjustment. The Tabucol algorithm is used to solve the established model and the results are perturbed. A set of predicted trajectories in a certain area is selected for simulation. It is shown that the combination of two strategies can effectively resolve the trajectory conflicts in this area. Compared with a single solution strategy, this method is more cost effective and feasible.
