基于多层QSI的航空联盟网络优化研究

Research on Optimization of Airline Network in Alliance Based on Multilevel QSI

结合多层服务质量指数模型对网络路径属性的预测,提出了一种联盟航线网络的优化方法.考虑了网络中不同OD市场竞争强度差异,多层QSI模型有效预测了航线产品的市场份额,进而得出航线路径市场份额.联盟航线网络优化模型以联盟内市场需求最大为目标,在干线运力约束下,以航线路径市场份额作为路径优选依据,对合作航线进行优化筛选.南方航空的航线网络优化实例分析验证了模型对于网络路径、枢纽机场的选择能够给出更好的优化结果,对航空公司的联盟战略决策提供有力的理论方法支持.

This article proposes an alliance network optimization model,combined with the prediction of network path attribute using multilevel QSI model.Taking ODs' different degree of competition into consideration,the multilevel QSI model effectively predicts the market share of airline products,corresponding to the market share of paths.Targeted at creating the largest demand within the limit of the capacity,the alliance network optimization model filters unfavorable paths in terms of market share of them.The case in China Southern Airline's network optimization proves that the optimization model is effective in path and hub choosing.It was also proved to be valuable in supporting alliance strategy formulation in the future.
