考虑碳减排的先进公铁转运系统选择研究

Research on Selection of Advanced Road-Rail Transshipment Systems Considering Carbon Emission Reduction

为了提高公铁转运效率和减少公路货运碳排放,在深入比较不同公铁转运系统运作模式的基础上,提出了偏好顺序结构评估法与傅勒三角形法相结合的公铁转运系统选择方法。首先根据不同选择需求,构建了包含碳减排量、碳减排收益、运营成本等10种指标的评价体系,采用傅勒三角形法确定各评价指标权重,然后以欧洲公铁转运系统项目数据为样本进行实证研究,利用Visual PROMETHEE软件,从碳排放减少量、运营成本、效率等10个维度对7种公铁转运系统进行评价。最后,以阿拉山口枢纽站为例,针对换轨耗时和存在碳排放问题,根据中欧公铁转运系统选择需求,设置不同权重,通过Visual PROMETHEE软件进行计算分析验证。研究表明,该选择方法简单易于操作,具有合理性和适用性,为企业选择公铁转运系统提供参考。

In order to improve the efficiency of road-rail transshipment and reduce the carbon emission of road freight,based on the in-depth comparison of the operation modes in different road-rail transshipment systems,a method selecting a road-rail transshipment system that combines the preference order structure evaluation method and the Fuller’s triangle method was proposed.Firstly,according to different selection requirements,an evaluation indicator system considering carbon emission reduction,carbon emission reduction benefits,operating costs,and other seven indicators was constructed,and the weight of each evaluation indicator was determined by Fuller's triangle method.With Visual PROMETHEE software,seven types of road-rail transshipment systems were evaluated from 10 dimensions such as carbon emission reduction,operating cost,and efficiency.Finally,Alashankou Junction Station was taken as an example.In view of the time-consuming and carbon emission problems of rail changing,different weights were set according to the selection requirements of road-rail transshipment systems,and the calculation analysis and verification were carried out with the Visual PROMETHEE software.The research shows that the selection method is simple easy to operate,and it is rational and applicable,which provides a reference for enterprises to choose road-rail transshipment systems.
