摘要:

开展技术站车流接续与区间列车运行调整的协同优化研究,利用区段在途列车的运行可调性实现运输区域的线流配合,优化运输生产指标。针对技术站车流接续与列车运行调整的关系,提出适流车组的概念,并从优化技术站车流接续的角度研究时段内相关到达、出发列车之间的关联关系。以技术站的期望到站时刻作为适流车组的运行调整目标,将该目标转换为到达列车的运行调整目标,并给出转换的方法和步骤。分析结果表明,传统线流配合研究主要针对站点的以流配线问题,而路网对站点以线配流的反向配合较少,将该线流配合从单向向双向拓展,可为技术站车流组织与列车运行调整协同优化研究的深化奠定基础。

Abstract:

This paper carries out the collaborative optimization of wagon-flow connection in technical stations and train operation adjustment in sections,realizes the transportation region’s line and flow cooperation by adjustment of trains on the way,and obtains better transportation production index.According to the relationship between wagon-flow connection in technical stations and the train operation adjustment,this paper proposes the concept of requiring wagons and builds the correlation between the arrival and departure trains during the research period from the angle of wagon-flow connection in technical stations.It takes the technical station’s expected arrival time as the operation adjustment target.There are few relative researches which take the wagon connecting optimization as the trains’ operation adjustment target.Analysis results show that the traditional research of line and flow cooperation mainly studies how to organize the flow in stations according to the lines,seldom researches how to adjust the lines on the network to match the flow in stations.This paper converts the one-way coordination into two-way coordination,and lays a foundation for further study on the collaborative optimization of wagon-flow organization and train operation adjustment in technical stations.

Key words: railway transportation, line and flow cooperation, wagon-flow allocation, operation adjustment, wagon-flow connection, mixed 0-1 programming
