将重载线路装车端作业区域按其货源供给水平及运输组织方式划分为战略装车点、装车区及装车域3个层次,并根据装车域列流组织的特点,以组合列车总组合时间及走行时间之和最小为目标,考虑线路年运量、通过能力、机车车辆数量等约束,并引入组合映射关系式表示组合站的列流接续关系,构建基于重载运输的装车域列流组织非线性整数规划模型,统筹优化组合站组合作业组织方案。最后以大秦线装车端的装车域为例,验证了模型的有效性和可行性。
According to the level of cargo supply and transportation organization, the loading area work area of heavy load line is divided into three levels: strategic loading point, loading area and loading area. According to the characteristics of loading area, Total combined time and travel time minimum as the goal, taking into account the annual traffic volume, capacity, number of locomotives and other constraints, and the introduction of the combination of mapping relationship between the flow of the combined station to show the relationship between the flow, build heavy loading transport loading The domain column flow organizes the non-linear integer programming model and co-ordinates the optimized combination station combination work organization plan. Finally, taking the loading area of Daqin line loading as an example, the validity and feasibility of the model are verified.
