Research on Optimization of Air-Rail Intermodal Transport Connection Scheme Integrating Differentiated Pricing Strategy

为提升空铁联运的服务水平与运营收益，本文借鉴“服务集成商”理念，将空铁联运运输企业定义为整合高铁与航空资源的协调主体。提出了一种融合差异化定价策略的接续方案优化方法，在优化列车与航班时刻表的同时，协同优化联运产品定价，以提高旅客吸引力并增加运营收益。以京广综合运输通道为背景进行实例分析，结果表明：优化后的空铁联运运营收益提升了48.4%，旅客量增加了45.7%，同时减少了无效接续导致的列车与航班时刻表调整成本，验证了所提优化方法的有效性。In order to improve the service level and operating income of air-rail intermodal transportation, this paper draws on the concept of “service integrator”, and defines the air-rail intermodal transportation enterprise as the coordination subject of integrating high-speed rail and aviation resources. An optimization method of connection scheme integrating differentiated pricing strategy is proposed. While optimizing the train and flight schedules, the pricing of intermodal products is collaboratively optimized to improve passenger attractiveness and increase operating income. Taking the Beijing-Guangzhou comprehensive transportation corridor as an example, the results show that the optimized air-rail intermodal operation income increases by 48.4%, the passenger volume increases by 45.7%, and the adjustment cost of train and flight schedule caused by invalid connection is reduced, which verifies the effectiveness of the proposed optimization method.
