货车周转时间是铁路运输货车运用效率的一项重要综合考核指标。首先通过对货车周转时间的分析,确定其影响因素;其次运用灰色关联法,提出货车周转时间影响因素的关联度分析模型;最后结合实例,对实例中货车周转时间各影响因素的主次关系作了定量分析,得出相应的结论:全周距呈缩短趋势,中距呈延长趋势,货物列车旅行速度呈提高趋势,中时、停时呈缩短趋势,在一定程度上抑制了货车周转时间的上升速度,这是以后提高车辆周转速度的主要途径。
Wagon turnaround time is an important comprehensive evaluation index for the efficiency of railway wagons. First of all, through the analysis of the turnaround time of freight wagons, the influential factors are determined. Secondly, the gray correlation method is used to present the relational analysis model of the influencing factors of wagon turnaround time. Finally, with the example, the relationship between primary and secondary factors Based on the quantitative analysis, the corresponding conclusions are drawn: the shortening trend of the whole week, the extension of the middle distance, the increasing speed of the freight trains, the shortening of the stopping time, and the suppression of the turnaround time of the trucks to a certain extent Rising speed, which is the main way to improve the speed of vehicle turnover in the future.
