摘要: 可持续航空燃料(Sustainable Aviation Fuel, SAF)具有显著减排潜力,但面临成本高昂和产量有限的现实难题。为提高航司使用SAF的效益,本文提出SAF、航线与机型的三维耦合优化方法,综合考虑机型燃油效率,航线成本以及碳排放层面的差异,以航空公司直接运营成本与碳排放量最小为目标建立SAF差异化配比优化模型。针对目标和约束的双线性特征,采用三阶段线性化策略实现模型重构,并设计结合ε约束的丹齐格-沃尔夫(Dantzig-Wolfe,DW)分解算法求解模型。最后,选取中国前5大航空公司、40个干线机场网络及10种主力机型为案例,结合24万条航迹数据,展开实例验证。结果表明,结合ε-约束的DW分解算法在求解效率和精度上均优于Gurobi直接求解。在较低减排水平下,SAF被集中配置于新一代窄体机的中程航线中,占使用总量的76.1%,此时,整体减排效益最佳。随减排量增加,宽体机在长航程上的配比逐步提升,SAF使用占比从7.3%提升至27.1%。这种差异化SAF配比方法较统一配比模式降低了碳排放约3.0%~4.8%。航线特征、航班规模与机型结构共同影响机场和航司最佳SAF配比和减排贡献。灵敏度分析表明,SAF供应量的增加以及SAF价格的降低将进一步提升SAF差异化配比方法的减排效益。本文为航空公司如何科学调控SAF掺混比例和提升减排效益提供了定量参考。

Abstract: Sustainable aviation fuel (SAF) has substantial decarbonization potential, yet faces practical constraints including high costs and limited supply. To improve the cost-effectiveness of SAF adoption by airlines, this study develops a three-dimensional coupled optimization framework linking SAF allocation, route characteristics, and aircraft types. By considering fuel efficiency differences at the aircraft level and cost and carbon emission variations at the route level, the study proposes an SAF differentiated blending optimization model to minimize airline operating costs and carbon emissions. A three-stage linearization strategy is used to linearize the bilinear objective and constraints, and a Dantzig-Wolfe (DW) decomposition algorithm with ε-constraints is applied to solve the model. A case study using data from the top five Chinese airlines, 40 major airports, and 10 aircraft models, along with 240 000 flight trajectory data points, is conducted. The results show that the DW decomposition algorithm with ε-constraints outperforms direct solving with Gurobi in both efficiency and accuracy. At lower abatement levels, SAF is concentrated on medium-haul operations of new-generation narrow-body aircraft, accounting for 76.1% of total SAF use, where overall mitigation effectiveness is maximized. As the abatement target increases, SAF allocation to wide-body aircraft on long-haul routes rises, with their share of SAF use increasing to 27.1%. Compared with a uniform blending scheme, this differentiated SAF allocation reduces emissions by approximately 3.0%~4.8%. Route characteristics, flight scale, and fleet composition jointly shape the optimal CO2 SAF blending strategy and mitigation contributions for airports and airlines. Sensitivity analysis indicates that increasing SAF supply and reducing SAF prices will further enhance emission reduction benefits. This study provides a quantitative reference for airlines to optimize SAF blending ratios to improve emission reduction outcomes.
