基于航班排队仿真的终端区空域容量评估

摘要

为提升多扇区终端区空域容量评估的实效性,基于终端区交通流显著的排队特性,结合考虑扇区耦合关系,建立仿真模型并给出新的评估方法.以成都终端区为例,选取一周航班计划,针对每日运行状况共进行35次仿真,评定成都终端区平行双跑道隔离运行模式下的空域容量为47架次/h,并指出空域划设缺陷.经管制员雷达模拟机演练及实际运行数据验证,新评估方法有效,评估结论更符合实际.%To improve practicability and effect of airspace capacity evaluation of terminal area with several sectors,new method was provided based on simulation model,considering traffic flow queuing characteristic and coupling relations between sectors in terminal area.Taking the Chengdu terminal area as an example,35 simulations were processed with every day's flights operation situation of one week,and the airspace capacity was evaluated as 47 aircrafts per hour under the model of segregated operations on two parallel runways,while defects of the airspace planning indicated.The evaluation conclusions were verified by radar simulator tests of air traffic controllers and cross-check with statistic data on real picture,and therefore the new method was proved to be more practicable and effective.
