【摘要】：以网络可达性和利用率最大为目标,建立货机班次分配与货物运输路径选择的多目标双层优化模型,针对我国基于审批方式为各航线分配航班的实际情况,通过调整货机班次优化航空货运网络布局.以20个机场组成的航空货运网络为例,设计NSGAII算法求解模型.结果表明:北京、上海、广州、深圳之间的航段将获得1/4的货机班次,他们是航空货运的枢纽机场;当决策者偏好网络可达性时,更多货机班次将被分配到大型机场间的航段上,当决策者偏好网络利用率时,货机班次在航段上的分配较均匀;随着货机班次在航段上由集中趋向分散,网络可达性降低而利用率提高;减少货机班次会降低网络可达性,增加货机班次会降低网络的利用率.
[Abstract]:Aiming at the maximum network accessibility and utilization ratio, a multi-objective bilevel optimization model of cargo flight frequency distribution and cargo transportation route selection is established, aiming at the actual situation of China's allocation of flights for each route based on the examination and approval method. Optimize the layout of air cargo network by adjusting the frequency of cargo aircraft. Taking the air cargo network composed of 20 airports as an example, the NSGAII algorithm is designed to solve the model. The results show that the flight segments between Beijing, Shanghai, Guangzhou and Shenzhen will receive a quarter of the number of freighters, which are hubs for air cargo; when decision makers prefer network accessibility, More freighters will be assigned to segments between large airports, and when decision makers prefer network utilization, the freighters will be more evenly distributed on the segments; as the freighters shift from centralization to dispersion on the freighters, The network accessibility is reduced and the utilization rate is improved, while the network accessibility is reduced by reducing the number of cargo aircraft, and the network utilization is reduced by increasing the number of cargo aircraft.
