摘 要: 对启发式算法中的A*搜索算法在航空器飞行冲突解脱策略中的应用进行研究。在分析适用于我国的冲突解脱策略的基础上,建立飞行冲突解决方案模型,构建以管制员工作负荷最小为优化目标的评价函数,给出算法流程图。仿真算例结果表明:所提出的方法能够在很大程度上减小管制指令的搜索空间,优化管制策略,为一线管制员的指挥提供科学的理论支持。

Abstract: A kind of heuristic arithmetic called A* arithmetic was studied in the field of flight conflict resolution strategy. Based on the analysis of conflict resolution strategy in China, a model of conflict resolution scheme was built in this paper. The cost function aimed at minimizing the working load of air traffic control (ATC) controller was designed, and the algorithmic framework was given. Results of simulation example showed that the method could reduce the searching space of controller’s instructions to a great extent, and optimize the controller’s strategy. Therefore, a scientific decision-making support has been proposed for the controller’s command.
Key words: air transport; decision-making support; A* arithmetic; flight conflict detection; flight conflict resolution
