对于货运列车的编组调度问题,建立了以压缩中时和增加运量为双目标、多约束的0-1规划模型,采用逐步紧缩中时约束的方法得到了问题一的调度方案.在此基础上对装载特别物资的车辆施加更强的中时约束得到了问题二的调度方案.提出了列车匹配系数的概念并建立了列车最优配对原则,根据该原则对列车进行优化编组得到了问题三的调度方案.基于问题二的数据转换处理得到了问题四的调度方案.
For the marshalling scheduling problems of freight trains, a 0-1 programming model with double targets and multiple constraints during mid-compression and incremental operations is established, and the scheduling scheme of Problem 1 is obtained by gradually tightening the mid-time constraints. On the vehicle loaded with special supplies more medium-time constraints got the scheduling problem of scheduling 2. Proposed the concept of train matching coefficient and the establishment of the principle of train optimal matching, according to the principle of the train optimization grouping has been the problem three Based on the problem of the two data conversion process has been the fourth of the scheduling solution.
