考虑碳排放的航空货运网络优化

为实现枢纽航线网络在经济效益与环境效益上的平衡，针对非严格的无容量限制单分配的P-hub货运航线网络优化问题，建立以经济成本最小为第一目标、以CO2排放量最小为第二目标的双目标优化模型。然后，基于国内顺丰航空公司的实际航线运营数据，利用MATLAB软件编程求解，分别对设置不同枢纽数量下的航线网络进行讨论分析。结果表明：网络运营成本随着枢纽点数量的增加呈现先减少后增加的趋势，飞机在运行过程中产生的CO2排放量也会呈现相同趋势；当枢纽数量为5个时，枢纽航线网络在降低运输成本方面具有较好优势, 枢纽数量为4个时，网络在降低碳排放成本方面具有较好优势。

Air Cargo Network Optimization Considering Carbon Emission

In order to achieve the balance between economic benefits and environmental benefits of the hub route network, aiming at the optimization problem of the non-strict P-hub cargo route network without capacity restriction, a dual-objective optimization model is established with the minimum economic cost as the first objective and the minimum CO2 emission as the second objective. Using MATLAB software programming solution, the route network with different number of hubs is discussed. The results show that the network operating cost decreases first and then increases with the increase of the number of pivot points, and the CO2 emissions produced by aircraft during operation also show the same trend. When the number of hubs is 5, the hub route network has a good advantage in reducing transportation cost, and when the number of hubs is 4, the network has a good advantage in reducing carbon emission cost.
