摘要
通过对机场建模,分析机场冲突热点的时空分布特征,构建航空器的滑行和避让机制,提出基于机场冲突热点的时空分布特征的航空器地面滑行路径优化模型。以机场的实际运行数据为例,结合该模型进行仿真分析,分析结果表明,优化后,该时间段内的航空器滑行总时间减少了238s,完全避免了潜在的滑行冲突,经过热点区域的航班由7架减少至3架,有效降低了原冲突热点区域的危险等级,对于保障机场安全运行效率有一定意义。
According to the establishment of model for aircraft, the analysis of the temporal-spatial distributions of hotspots, and the building of aircraft taxiing avoidance mechanism, aircraft taxiing route optimization model based on temporal-spatial distribu- tions of hotspots was proposed. Using the actual operation data got from the airport as an example, the proposed route optimiza tion model was adopted for simulation and analysis. Simulation results indicate that total taxiing time is reduced by 238 s after optimization and no taxiing conflict occurs. Meanwhile, the number of flights that taxi through hotspots area is reduced from 7 to 3, which effectively alleviates the risk level of hotspots and improves airport operation safety.
