基于批量订购的铁路集装箱货运多等级运价研究

铁路集装箱货运发展迅速，在铁路货运中占比逐渐增大.当前铁路总公司没有针对 大批量订购采取优惠折扣，导致部分客户转向其他运输方式.针对这个问题，设计了多等级运 输价格策略来吸引大客户，建立了铁路集装箱货运收益最大的动态价格模型，求解出各订购 量对应的最优价格等级.本文以大朗到大红门的集装箱货运班列为例，求解出不同时刻各订购 量的最优等级运价.通过对比优化前后的结果，证明了该模型可以显著提高铁路集装箱运输的 收益.

Multi-class Freight Rate of Railway Container Freight Based on Lot Sizing Order

The proportion of railway container freight transportation is now increasing gradually with its rapid development. Recently, railway corporation doesn’t discount according lot sizing order which results in some customers choosing another mode of transportation. Aimed at this question, the strategy of multi-class freight rate is designed to appeal to key accounts. The dynamic pricing model is set to maximize the expected revenue of railway container freight, to solve the optimal price class of each order quantity. This paper takes the line of container freight from Dalang to Dahongmen as an example, and solves the optimal freight rate of each order in different time. The proposed method is proved that it could improve the revenue of railway container freight observably by comparing results before and after optimization.
