铁路运营指标都是由一定因素构成的。因此,指标的完成情况与各因素的变化密切相关。在铁路运营工作分析中,为查明一定指标完成情况的原因,以便进一步拟定改善铁路运营工作的措施,一般均应就指标因素的影响情况作出分析。本文提出了指标因素影响分析的基本原理,并根据这一基本原理,对货车周转时间的因素影响及其他主要货车运用指标的局(分局)别影响分析的计算方法作了具体说明。
Railway operation indicators are constituted by certain factors. Therefore, the completion of the indicator is closely related to the changes of various factors. In the analysis of railway operation, in order to find out the reasons for the accomplishment of certain indicators so as to further formulate the measures to improve the railway operation, we should generally analyze the impact of the indicator factors. In this paper, the basic principles of the impact analysis of index factors are put forward. Based on this basic principle, the influence factors of the turnaround time of trucks and the calculation methods of the impact analysis of other bureaus of railway trucks are explained in detail.
