摘　　要：针对传统货运航线网络设计中仅考虑经济目标而忽视环境影响的问题,在绿色民航的背景下,提出一种综合考虑经济目标和环境影响的货运航线网络优化方法。基于多分配严格枢纽航线网络,以经济成本、CO_(2)、CO和NO_(x)排放量最小为目标,构建相应的数学模型。采用线性加权和法与分支定界法结合案例求解。结果显示,不同优化目标下的航线网络结构存在一定差异,难以同时达到最优。与仅考虑经济成本的求解方案相比,采用本文的综合求解方案,能够实现经济效益和环境效益间的较好均衡。In response to the problem of traditional freight route network designs focusing solely on economic objectives while neglecting environmental impacts,a comprehensive optimization method for freight route network considering both economic goals and environmental effects was proposed in the context of green aviation.Based on a multi-allocation strict hub-and-spoke route network,a mathematical model was constructed with the objectives of minimizing economic costs,CO_2,CO and No_(x)emissions.Linear weighting method and branch-and-bound algorithm were employed for solution in conjunction.The results indicate that there are certain differences in the route network structures under different optimization objectives,making it challenging to simultaneously achieve optimality.Compared to solutions that only consider economic costs,the comprehensive solution proposed in this paper achieves a better balance between economic benefits and environmental impacts.
