Identification of Capability Bottleneck of Railway Corridor and Corresponding Solution

铁路通道能力瓶颈进行识别与消解是铁路通道能力利用和加强的重要途径。为了提升铁路通道能力利用,采用大数据技术,依托铁路运营数据处理分析,对TDCS和车站资料获取的数据进行预处理,实现参数确定和能力瓶颈识别,并根据瓶颈点参数建立数学模型并求解,构建通道能力利用备选方案集,基于仿真模型实现对方案的迭代优化,达到瓶颈消解和能力协调优化的目标。以包神铁路煤运通道为例,应用提出的优化方法对通道能力瓶颈进行识别和消解,优化结果表明运输方案各类指标得到明显的改善,各区间能力利用率更加均衡。

Identification of capacity bottleneck of the railway corridor and the corresponding resolutions are essential to enhance the capacity of railway corridor.In order to improve the utilization of railway corridor capacity,this paper uses big data technology,relying on the analysis of railway operation data processing,to preprocess the data obtained from TDCS and station material,so as to determine parameters and identify capacity bottleneck.Then,the mathematical model is established and solved according to the bottleneck parameters,and the set of alternatives for corridor capacity utilization is constructed.Furthermore,based on the simulation model,the iterative optimization of the scheme is realized to achieve the goal of bottleneck resolution and capacity coordination optimization.Taking the coal transportation corridor of Baoshen railway as a study case,the proposed optimization method is applied to identify the bottleneck of corridor capacity.The optimization results show that the various indicators of the transportation strategy have been significantly improved,and the capacity utilization rate of each section has become more balanced.
