全货运航空公司单分配严格枢纽航线网络优化设计

Optimal Design of Single Distribution Strict Hub Route Network for Cargo Airline

针对全货运航空公司,研究其货运航线网络的构建问题。基于单分配严格枢纽航线网络,对传统模型进行改进。以各航线上货物的委托运输成本和自有机队的运输成本,取代传统的单位运输成本和折扣因子,考虑枢纽点的中转成本和载运率对路径选择的影响。结合航空货运夜航的特征考虑各机队夜间可用时间的限制,以总成本最小为目标,构建数学模型,采用LINGO优化软件求解,验证模型的有效性,为全货运航空公司构建货运航线网络提供参考。

Research the construction of rute network for cargo airlines.Improve the traditional model based on a single allocation strict hub route network.Replace the traditional unit transportation cost and discount factor with the commissioned transportation cost of goods on each route and the transportation cost of its own fleet,and consider the impact of the transit cost and loading rate of hub points on route selection.Considering the characteristics of air cargo night flights and the limitations of available time for each fleet at night,with the goal of minimizing total cost,a mathematical model is constructed and solved using LINGO optimization software to verify the effectiveness of the model,providing reference for freight airlines to build a freight route network.
