铁运提速后的货物物流运达期限改进算法及实证分析

Empirical Analysis of Improved Algorithm for Deadline for Cargo Logistics Delivery after Acceleration of Railway Transportation

通过对目前有关铁路运输运达期限文献的研究,发现货物运达期限的理论研究居多,而对于当前铁路交通提速条件下的货物运达期限方法研究的文献很少,因此,分析了传统的货物运达期限算法的局限性,运用统计分析方法,研究了铁路运输货物的日均运价里程,并对其进行了χ2检验,同时提出了适用于铁路交通提速条件的货物运达期限的算法。通过在哈尔滨铁路局的三棵树站、上海铁路局的合肥站、南昌铁路局的向塘站的实际应用,将计算结果与传统算法的结果进行了对比,表明该算法算出的运达期限和货运时间存在很大的契合性,并且比传统算法更加精确。

In this paper, through studying the available literatures concerning the delivery deadline in railway freight transportation, we identified the existing problems in this academic field, then accordingly, analyzed the limitations of the traditional algorithm in determining the freight delivery deadline, then proposed a process to improve it, and at the end, through applying the improved algorithm to the Sankeshu Station of the Harbin Railway Bureau, the Hefei Station of the Shanghai Railway Bureau and the Xiangtang Station of the Nanchang Railway Bureau, demonstrated its superiority over the original algorithm.
