碳排放的铁路集装箱多式联运路径优化研究

Research on Optimization of Railway Container Multimodal Transportation Path Based on Carbon Emission

在铁路中集装箱运输方式具有重要的发展意义,集装箱多式联运优势较多,能够提高货物的运输效率和效益,提高客户的满意度,而且还有助于降低环境污染,尤其是铁路运输方式的使用,相对于公路而言,能够大幅度降低能源消耗和碳排放量。在我国不断强调和提倡节能环保的理念下,降低铁路运输过程中的碳排放量有助于保护环境。于是文章主要研究考虑碳排放量下铁路集装箱多式联运的路径优化。在建模过程中主要以碳排放成本和运输成本作为目标,使得两者的综合成本最低为最优运输路径。建模完成之后进行算例分析,将考虑碳排放和不考虑碳排放的总成本进行对比,结果表明,文章所研究的模型其碳排放量能够降低40%左右。

Container transportation in railways has important development significance.Container multimodal transportation has many advantages,which can improve the efficiency and benefit of cargo transportation,increase customer satisfaction,and also help reduce environmental pollution,especially railway transportation.The use of transportation methods can greatly reduce energy consumption and carbon emissions compared to roads.With the continuous emphasis and promotion of energy conservation and environmental protection in our country,reducing carbon emissions during railway transportation will help protect the environment.Therefore,the paper mainly studies the route optimization of railway container multimodal transportation under the consideration of carbon emissions.In the modeling process,carbon emission cost and transportation cost are mainly used as targets,so that the lowest comprehensive cost of the two is the optimal transportation route.After the modeling is completed,a case study will be performed to compare the total cost with and without carbon emissions.The results show that the model studied in this paper can reduce carbon emissions by about 40%.
