Dynamic Pricing Model of Container Sea-Rail Intermodal Transport on Single OD Line

In the management of container sea-rail intermodal transportation, dynamic pricing problem with uncertain conditions has significant impacts on the benefit and competitiveness of a multimodal transport operator. Based on the revenue management theory and the features of container sea-rail intermodal transport, this paper develops a two stages optimal model which integrates dynamic pricing and slot allocation on single origin-destination line. The first stage is proposed by considering long-term slot allocation in contract market, and the second stage is set up in consideration of the dynamic pricing in free market. Because of the demand uncertainty and the statistic error characteristics, the method of chance constrained programming and a robust optimization model are used to solve the models, respectively. The simulation shows the feasibility and efficiency of the proposed models and algorithms.
