摘要
不同运输方式存在运输价格、安全性、时效性和便捷性等方面的差异,这几个因素决定了货物运输的广义费用.客户总是选择对自身来说广义费用最小的运输方式.快捷货物运输是铁路近几年开发的货运新品种,在定价方面主要依赖个人经验,缺乏理论依据.为此,本文研究了多种运输方式竞争下铁路快捷货物运输的动态定价方法,提出用户广义费用最小化模型和双层规划模型,并通过呼和浩特至北京的货运数据比较了这两种定价模型对定价及总利润的影响.结果表明,双层规划模型优于广义费用最小化模型.
The main differences among the modes of transport are prices, safety, timeliness and convenience, etc. Those factors determine the generalized cost. And the customers will always choose a transportation mode of which the generalized cost is minimum. In this paper, a kind of dynamic pricing method for the express rail freight transportation is provided. At the same time, a model based on the generalized cost and a bi-level model are proposed. Finally, a comparison analyze of the influence on pricing strategies for railway enterprise is studied based on the data of Huhehaote to Beijing freight. The results show that the bi-level model does better than the another model in increasing profit for railway enterprise.
