摘要:为降低铁路冷链运输模式评价过程中决策分析的主观性,解决运输服务体系不易评价的问题,分析我国铁路冷链运输的影响因素,构建铁路冷链运输模式评价指标体系;采用熵值法计算铁路冷链运输模式评价指标的权重,进行重要性排序,根据评价指标的突变类型,建立熵值-突变级数铁路冷链运输模式评价模型。以我国铁路冷链运输的3种模式为例进行评价分析,结果表明:铁路冷藏集装箱特需专列得分最高,铁路冷藏快运专列得分最低,评价结果符合实际。熵值-突变级数铁路冷链运输模式评价模型可以克服主观赋权的局限,计算简单,具有较高的应用价值。

Abstract: In order to reduce the subjectivity of decision-making analysis in the evaluation process of railway cold chain transport mode and evaluate the transport service system easily, the key elements affecting railway cold chain transport are analyzed and the evaluation index system of railway cold chain transport mode is constructed. The weight of evaluation index of railway cold chain transportation mode is calculated by entropy method and the importance is ranked. According to the mutation type of the rating index, the evaluation model of railway cold chain transportation mode by entropy-mutation progression method is established. Taking three railway cold chain approaches in China as examples,the results show that the railway refrigerated container special train has the highest score, and the railway refrigerated express special train has the lowest score. The evaluation results are in line with the reality. The entropy-catastrophe progression method surpasses the limitation of subjective weight assignment, the calculation is simple and has high practical value.
