枢纽机场空侧容量利用和流量分配优化模型

通过引入满意度函数,以航班流量和容量利用满意度最大化为目标,建立了机场空侧定位点流量分配和跑道容量利用的多目标优化模型。利用ILOG对模型算例进行了求解。结果表明,采用本文模型求解得到的各个定位点的整体航班需求排队队列比Gilbo模型的结果减少了10%。在研究时间段内(3 h),通过优化分配各个时间间隔(15 min)各定位点的进离港航班流量,所有航班需求得到满足且在最后的时间间隔没有产生延误队列,从而又保证了一定的容量利用满意度(h=0.75),实现了机场终端区某一特定时段内现有容量更有效的利用,减少了航班延误。

Optimization Model of Hub-Airport Airside Capacity Utilization and Flow Allocation

The airside capacity utilization and the traffic flow distribution are optimized with multi-objective model for maximizing flow through runway and arrival/departure fix by introducing utilization satisfaction level.The model is verified with example solutions by ILOG OPL studio.The result indicates that the proposed algorithm is effective to decrease overall flight demand queues by 10% compared with previous results.Within the considered time period(3 h),all flight demands are satisfied without any delay at the end of the last 15 min interval by optimal allocation of flow for each arrival/demand fix of airside.Thus it guarantees the capacity utilization satisfaction level(h=0.75) and gives an effective utilization of airport airside capacity,and reduces flight delays.
