运用矩阵分析法分析货车周转时间的影响因素,运用灰色关联分析法对各因素间的主次关系作了定量研究,从中得出结论:与货车周转时间关联最紧密的因素是停时、中时;客观因素全周距增幅较大,这是导致近2年来货车周转时间较历史最好水平延长的主要原因;货物列车旅行速度呈缓步提高趋势,中时、停时呈缩短趋势,在一定程度上抑制了周时的上升速度,这是以后提高车辆周转速度的主要途径.
Using matrix analysis method to analyze the influencing factors of the turnaround time of freight wagon, the gray relational analysis method is used to quantitatively study the primary and secondary relationships among various factors, and the conclusion is drawn that the most closely related factors to wagon turnaround time are stopping time, ; The objective factors were greatly increased over the whole week, which was the main reason that the turnover time of freight cars was longer than the historical best in the past two years. The travel speed of freight trains showed a gradual increase trend. During the mid-term, the stopping time showed a shortening trend. To a certain extent, it restrained the rising speed of the week, which is the main way to increase the turnover speed of the vehicles in the future.
