铁路日常计划和统计中如何简便而准确地计算货车周转时间的问题,在理论和实践中一直是一个讨论的课题。本文提出了按车流构成对周时的影响和相应的计算方法修正由于车流构成,尤其是空车流构成的变化造成日间计划中货车周转时间指标值的误差。本文还提出了对局(分局)的分界口出入车按车列(或车组)计算其换算车小时的方法,求其一昼夜消耗的车辆日,以准确地得出运用车数,并按车辆相关法算出货车周转时间。此法简明准确,可在现有统计资料的基础上完成。本文并做出应用电子计算机实现的框图。
The problem of how to calculate the turnaround time of freight wagons easily and accurately in railway daily plans and statistics has always been a topic of discussion in both theory and practice. In this paper, the influence of traffic composition on the weekly time and the corresponding calculation method are proposed to correct the error of the indicator value of the truck turnover time in the daytime plan due to the change of traffic composition, especially the composition of empty traffic flow. This paper also proposed the method of entering and exiting the boundary of the bureau (branch) to calculate the car hour by vehicle train (or train set), and calculates the day of the vehicle consumed day and night so as to obtain the exact number of vehicles and press the vehicle Relevant law calculate the truck turnaround time. This method is concise and accurate and can be done on the basis of the existing statistics. This article also makes a block diagram of the application of electronic computer.
