基于鲁棒性的竞争环境下枢纽航线网络优化设计

针对当前航空运输网络的逐步复杂化，通过对枢纽机场选址模式的分析，研究 竞争环境下枢纽航线网络设计方案.首先，在一定的航线网络基础上，定义了旅客效用函 数及捕获能力函数.然后在原有枢纽的基础上，以从竞争者那里获得的最大捕获流为目 标，选址新的枢纽，建立竞争环境下枢纽逐步选择模型，并且设计了求解模型的高效算法. 最后，通过随机产生的案例应用模型，分析模型中各参数变动的情形下，所得枢纽解的情 况；同时，通过枢纽解对计划延误时间的敏感性分析，验证最优枢纽解的稳定性，进而验 证模型的有效性.该模型可为航空公司的航线规划人员提供依据.

Optimal Design of Hub Network in Competitive Environment Based on Robust

According to the complexity of air transport network, the paper analyzes a hub airport site model and researches hub route network design competitive environment. First, it defines a passenger capacity utility function and capture function on the basis of certain route network. Then, on the basis of the existing hub, under the goals of that obtain maximum passenger capture flow from rivals, screening the new hub location, establishing stepwise hub selection model in competitive environment, and an efficient algorithm is proposed to solve the model. Finally, a random case is selected to test the model, analysis of Hub solution on variation of the parameters in model; by analyzing sensitivity of the projected delay time, verifying the stability solution of optimal hub and the effectiveness of the model. The model can provide a basis for the route planning personnel.
