Research On Optimization Of Train Sorting And Classifying Plan In Marshalling Station

Marshalling station is the key node of the railway freight transportation, which occupies an important position in the railway freight transportation. Marshalling station’s operation process and operation system is also one of the most complicated part of the railway system. In recent years, in order to improving comprehensive ability of the marshalling station, the railway marshalling yards has done a lot of improvement in station operation plan optimization and station operation information system construction. However, due to the technical inspection of the connecting time,train departure time, which are a series of strong randomness、the influence of uncontrollable factors, bring much interference on train sorting and classifying in marshalling stations. The main content of this article is to researching on coordination optimization of train sorting and classifying in marshalling stations, in order to realizing the optimization of station operation plan.Firstly, This article builds the main body of the article structure based on the domestic and foreign research results.Secondly, the article introduces some related theories on train sorting and classifying in marshalling stations, it introduces the solution of the marshalling station system, and analyzes the traffic organization and the influence of the marshalling yards solution encoding system, something about process, content and characteristics of the marshalling station stage plan is analyzed,and the relationship between described to understand the order and the marshalling yards with the relationship between sequence of train sorting and classifyingand the flow in marshalling stations. Thirdly, this article studies the solution of the sequence of train sorting and classifying in marshalling station .of train in the marshalling station train in detail order adjustment method of research, includes the optimized content, marshalling sequence of adjustment scheme, the order of the collapse of the scheme. The article put forward to some related concepts and conditions about coordination optimization of train sorting and classifying in marshalling station.And the organization of the marshalling station departure trains are divided into tracking marshaling and across sequence train, at the same time to subdivide the collapse of the train for tracking the collapse of the train and across sequence train. At last, this article chooses the Chongqing xinglongchang marshalling station as a case to research the coordination optimization of train sorting and classifying in this marshalling station based on a class in 2015,in order to achieving the optimal with the overall flow.
