摘要: 研究了包括多个扇区的区域容量评估问题, 通过分析飞行流量在空域单元之间产生耦合约束因素, 提出了空域单元的耦合容量, 研究了区域耦合容量的影响因素。结合管制员工作负荷等限制建立了区域耦合容量的多目标整数规划模型, 并使用该模型计算了兰州区域各空域单元耦合容量。计算结果表明: 扇区1、2、3耦合容量分别为22、19、33架次.h-1, 小于其最大容量; 区域耦合容量小于区域仿真容量评估结果, 因此, 该模型更有利于合理分配空域资源。Abstract: The capacity evaluating problem of area with several sectors was studied, and the limitation of flight flow coupling existing between airspace units was analyzed.The coupling capacities of airspace units were defined, and their influecing factors were analyzed.A multi-objective integral optimization model of area coupling capacity under the constraints of controller workload was presented, and was used to calculate the coupling capacities of airspace units in Lanzhou area.Analysis result shows that the coupling capacities of sectors 1, 2, 3 are 22, 19, 33 flights·h-1, which are less than their max capacities, and the area coupling capacity is less than the simulation evaluation result.Therefore, the model is more advantageous to distribute airspace resources.
