基于层次分析法的大准铁路点岱沟车站列车停时优化研究

Study about Optimization of Cargo Operation Stay Time of Diandaigou Station in Dazhun Railway that Based on Analytic Hierarchy Process

大准铁路是蒙西地区煤炭外运的重要通道,点岱沟车站是大准铁路的主要装车站之一。压缩列车站停时间能够极大地提升运输效率和降低运输成本。本文以点岱沟站实际作业数据为基础,建立列车到达装车作业排队系统模型对点岱沟车站的列车停时进行了定量评价。在此基础上,提出了压缩点岱沟车站停时的具体措施,并用层次分析法进行了定量评判。

Dazhun railway is an important channel for coal transportation in western Inner Mongolia.Diandaigou Station is one of the main loading stations of Dazhun railway.Compressing the stay time of cargo operation at the station can greatly improve the transportation efficiency and reduce the transportation cost.Based on the actu-al work data of Diandaigou Station,this paper establishes a train arrival queue model to make a quantitative evaluation about the parking time of Diandaigou Station.And then specific measures to condense the stope time of the station are put forward on the basis,and using AHP for quantitative evaluation.
