基于滚动模糊时间窗的场面动态路径规划

为了减少机场场面滑行冲突,提高机场运行效率,提出了一种基于模糊规则系统的滚动模糊时间窗算法。首先构建机场滑行时间预测模型,其次将滚动时间窗和模糊时间窗算法相结合,对滑行路径进行动态优化,最后结合机场地面滑行数据进行检验,结果表明,地面延误降低了9%-17%,地面冲突减少了10%-18%,说明该方法能够有效提高机场地面运行效率。

A research of dynamic route planning for ground aircraft based on rolling fuzzy time windows

In order to minimize airport ground taxiing conflicts and increase airport operating efficiency, a fuzzy time window algorithm based on a fuzzy rule structure is proposed. Firstly, the airport taxiing time prediction model is constructed; secondly, the rolling time window and the fuzzy time window algorithm are combined to dynamically optimize the taxiing path; And finally, the results are tested in accordance with airport ground taxiing date, which show that the ground delay is reduced by 9%-17% and the ground conflict is reduced by 10%-18%, suggesting that the approach can effectively boost airport ground operating efficiency.
