Aircraft conflict resolution is an important part of air traffic control operations. This study presents a mixed integer linear programming model (MILP) using a space discretisation technique to deal with aircraft conflict resolutions in en-route flight operations. The purpose of space discretisation is to concentrate on only the significant points of the airspace. The model integrates the multi entry point approach with an airspeed adjustment technique in the horizontal plane. The model aims to generate conflict-free trajectories while minimising the total changes in entry points and airspeed values. A new heuristic algorithm was developed due to the complexity of the problem. The computational results demonstrated that the proposed approach resolved aircraft conflicts for 450 different traffic scenarios in less than a minute. Considerable fuel savings were achieved with no significant increase in delay or flight time compared to conventional vectoring techniques in a fixed entry point airspace structure.

使用启发式算法进行水平分辨率机动的无冲突航路操作

飞机冲突解决是空中交通管制行动的重要组成部分。本研究提出了一种混合整数线性规划模型 (MILP),该模型使用空间离散化技术来处理航路飞行操作中的飞机冲突解决方案。空间离散化的目的是只关注空域的重要点。该模型将多入口点方法与水平面的空速调整技术相结合。该模型旨在生成无冲突轨迹,同时最小化入口点和空速值的总变化。由于问题的复杂性,开发了一种新的启发式算法。计算结果表明,所提出的方法在不到一分钟的时间内解决了 450 种不同交通场景的飞机冲突。
