Question

In this paper, various strategies for minimizing the amount of switching done at a classification yard are examined. We investigate how the allocation of blocks (the sorting classes recognized at the yard) to classification tracks affects switching work. Given are the sorting classes, as well as the schedule and block make up of the departing trains. Only static strategies are considered-strategies where every block has been assigned permanently to a classification track. Simple formulas are given for the minimum number of tracks needed to implement a strategy, and for the amount of switching work given a number of tracks. The total track length is also examined. The results are significantly influenced by the number of blocks recognized by the yard; given this number, the results are nearly independent of the train departure schedule, the number of departing trains, and the number of blocks of individual trains. This feature simplifies the study of larger problems (e.g., dynamic blocking strategies ) and, most importantly, makes train formation and scheduling an easier job at every yard.

Answer 1

在本文，各种各样的战略为使相当数量开关减到最小完成在一个编组场被审查。 我们调查怎么块(排序的类的分派被认可在围场)对分类交换工作的轨道影响。 给出排序的类，以及日程表和块组成离去的火车。 仅静态战略是考虑战略，每个块永久地被分配了到分类轨道。 简单的惯例被给为必要的轨道的最小数字实施战略和为开关工作指定的相当数量一定数量的轨道。 总轨道长度也被审查。 结果被围场认可的块的数量显著影响; 给出这个数字，结果几乎是火车离开日程表的独立，离去的火车的数量和各自的火车块的数量。 这个特点简化更大的问题(即，动态阻拦的战略)的研究，并且，最重要，牌子训练形成和预定一个更加容易的工作在每个围场。
