Research on Capacity Coordination of Loading and Unloading Wagon Flow on Heavy-Haul Railway

摘要

This paper has carried out some researches on organization method of wagon flow of coal transportation corridor to meet the demand of heavy-haul railway. To improve the capacity of a collecting and distributing system, the optimal problem is described as: coordination of loading capacity and unloading capacity to determine the wagon flow. Based on the analysis of the capacity of loading end and unloading end of Daqin Railway, the model with the minimization of the transportation price and the idle cost of the equipment and the maximization of the total loading and unloading wagons of the system is constructed. Then the paper transformed this multi-objective programming into a transportation problem by using main objective method, so that the model can be solved easily. Finally, by solving of the problem respectively on Daqin Railway, the model is proved to use on capacity coordination of loading and unloading stations on heavy-haul railway.
