摘要

Faced up with the severe competition in the market, the express rail freight transportation management needs appropriate pricing mechanism to improve the efficiency and benefit. The bi-level pricing model is established, including the lower layer model of cargo flow modal split based on the consignors' choices, and the upper layer one aiming at maximizing the benefit of railway enterprises. The improved heuristic algorithm is used in the solution of the bi-level model. The example shows that the express rail freight transportation product has a strong competitive advantage among all the products of other transportation modes with optimum price.
