箱种及车种代用下铁路集装箱空箱调配研究

Study of the Railway Empty Container Distribution with Substitution of Car and Container Types

在铁路集装箱空箱调运过程中考虑车种和箱种的代用,能有效降低空箱调运成本、提高空箱调运效率。在分析箱种及车种代用对空箱调配影响的基础上,以空箱调运费用为最小目标,建立空箱调运的整数规划模型。最后通过算例实现并进行模型特征的分析,证明箱种代用能够实现优化空箱调运方案、降低空箱调运费用目的。

Considering the substitution of car and container types can lower the cost and increase the efficiency of empty container allocation .A model of empty container distribution with a minimum cost being the object is established ,based on the analysis of the influence of substitution of car and container types .Finally ,the realization of the calculation example and the analysis of the model characters proved that substitution of container types can reduce transportation cost ,and is advantageous to the optimization of railway empty container distribution .
