铁路编组场线路固定使用方案优选方法研究

为了合理使用编组场分类线,保证按编组计划编车、按运行图行车,每个编组站对其编组场分类线的使用都进行了相对固定的分工。针对编组场线路固定使用方案的编制目前还缺乏足够的定量分析方法,提出编组场线路固定使用方案以及各使用方案所对应的编组作业所耗费的调车作业成本的计算方法,为编组场线路固定使用方案的最终确定提供定量化的决策依据。在此基础上,对定性与定量分析相结合的编组场线路固定使用方案优选方法进行了阐述。

Studying of optimization of fixed usage plan for railway marshalling yard tracks

In order to make full use of the marshalling yard tracks,the usage of the marshalling yard tracks in a marshalling station was fixed to ensure making up trains for the train plan and running trains for the train timetable.In view of the lack of quantitative analysis methods to make fixed usage plan for marshalling yard tracks,the calculation methods for finding the number of the fixed yard track usage plan and its corresponding marshalling operation costs were proposed in this paper.The results provide quantitative basis for the final determination on the fixed usage plan of the yard tracks.Based on this,an optimization method combined qualitative analysis with quantitative analysis is described for the fixed usage plan of the yard tracks.
