摘　　要：针对货运航线网络枢纽选址问题中经济效益与环境效益的平衡问题,考虑航空器碳排放成本,以网络总成本最小化为目标优化函数,建立有容量限制的货运航线网络枢纽选址绿色优化模型,采用免疫遗传算法求解并进行算例分析。结果表明:1)枢纽运输成本系数可决定航司进行货流转运的运输成本大小,运输成本系数变小,航司更应选择枢纽点转运,发挥网络的规模经济效用进行成本节省增加利润。2)枢纽转运点位置规划结果主要集中于东部地区城市。随着货运航线网络枢纽转运点数量建设的增多,总成本会出现先减小后增加的趋势,航司应根据自身机队规模及货运需求实际来构建合理位置与数目的转运节点。Aiming at the balance between economic and environmental benefits in the location of freight route network hubs,considering the cost of carbon emissions from aircraft,a green optimization model for hub location of capacity-constrained freight route networks is developed with the minimization of total network costs as the objective optimization function,and an immune genetic algorithm is used to solve and analyze the calculation cases.The results show that the transportation cost coefficient of hub transportation can determine the transportation cost of cargo flow transshipment by the airline.The transportation cost coefficient becomes smaller.The airline should choose the hub transshipment point to transport,and play the economies of scale of the network to save costs and increase profits.The hub transit point location planning results are mainly concentrated in developed cities in the eastern region.With the increase in the number of hub transfer points in the freight route network,the total cost will decrease first and then increase.Airlines should build reasonable positions and numbers of transfer points according to their fleet size and freight demand.
