The Research Of The Occupation Plan Of Line And Route Of Heavy Haul Railway Station

The capacity of the heavy-haul railway station is that under the fixed conditions of the station,the number of train stations is passing through trains day and night,as the heavy Load line node,which often affects the passing ability of the whole railway network.With the requirement of internal and external policies such as "Thirteen-Five" Planning and "all the way",it is necessary to optimize the management technology of heavy-haul railway to match the strengthening of the heavy haul railway freight transport distance.This paper considers the equipment management of heavy haul railway station to realize the utilization of equipment and increase the balance of equipment utilization,so as to improve the operation efficiency of the whole station and line.And this paper designs the Occupancy organization optimization scheme of the station's line and route to improve the capacity of the station,including:(1)Introduction of related concepts of heavy haul railways and research on optimization of line and route occupancy at home and abroadFirstly,it introduces the concept,definition,development and mode of heavy haul railway transportation,and analyzes its characteristics.Then the mathematical modeling optimization and the solution and the simulation optimization modeling and solving of the line and the route occupation are summarized,and the optimization of the overseas station passing capacity is summarized from the optimization of the line and route and the related algorithms used in the model solving process.(2)Analysis of factors affecting the line and route occupancyFrom the station line,the station Ping,the station type construction,the transformation,the traction power supply Equipment upgrade transformation,the train diagram optimization,the station train operation type and the flow and so on aspect to carry on the analysis to the line and the route occupation influence factor.The types and flow of train operation in heavy haul railway station are analyzed from two aspects of general operation and comprehensive operation.(3)The construction and solution of the optimization mathematical model of the railway station's line and route selectionOn the basis of general passenger station or cargo terminal model,in order to increase the locomotive correlation constraint and variable of the train corner operation and the million ton combination operation,the objective function is to choose the inclination of the stock channel and the equilibrium of the stock channel occupation,and to take the related principles of the stock channel and the route related occupation,the locomotive shunting the car occupancy and the train combination.Two times 0-1 programming model and one 0-1 programming model were constructed.(4)Case studyTaking the Kiln Bay station of Bao-Shen Railway as a case,this paper introduces the Kiln Bay station from three aspects of station layout,turnout grouping and route information and flow path.By analyzing,solving or importing relevant parameters,and then using lingo to do integer linear programming,the optimal solution or the better solution opt and the corresponding value of all variable x are obtained.Finally,the result of the solution is sorted and analyzed.
