摘要: 快速货运是一种现代化的运愉生产方式,是未来货物运输的发展趋势之一在快速货运系统设计及运行过程中,知何科学、合理地选择快速货运的运送路径则成为必须解决的关健问题.快速货运系统路径选择涉及到运输方式选择、运输路线确定等问题,受到多种相互关联又相互制约因素的影响,是一个复杂的系统问题.本文首先分析了影响快速货运系统路径选择的因素,并提出了相应的评价指标体系,在此基础上,应用灰色关联分析方法建立了快速货运路径优选模型,在确定各指标权重时,采用了嫡的概念,避免了人为主观因素的影响.最后的实例计算显示该方法是可行、实用的.

Abstract: Express freight transportation is a kind of modern transportation production styles, which is one of development trends of future freight transportation. Route selection for express freight transportation system is a key problem which should be resolved in the procedure of express freight transportation system planning and operating. Route selection is a complicated problem, which is associated with many factors. In this paper, factors influencing route selection of express freight transportation system are analyzed, and corresponding evaluation indices are introduced. Furthermore,an optimal route selection model is set up by applying grey relational grade (GRG) analysis. The index-weight is determined based on the theory of entropy, thus the effect of subjective factorsi sa voided.Finally,a calculating example is given,which proves the model feasible and practicable.

Key words: express freight transportation, grey theory, route selection, entropy
