遵守车站股道运用条件,在引入时间窗、权重和有限度3个参数的基础上,利用排序理论构建车站股道运用排序模型。结合列车在车站的实际作业过程和进路编排,利用启发式算法对模型求解,得到股道运用初始方案。基于排序原则选择、进路编排方式和多方案选优3种解改进策略对股道运用初始方案进行改进,得到股道运用改进方案。利用现代柔性理论,设置1个人—机交互接口,以股道运用可行性为第1优化目标、均衡性为第2优化目标,建立股道运用的柔性模型,按照人—机交互会话的方式进行求解。采用该模型与算法编制的铁路车站股道运用自动编排系统,目前已在广州东站和韶关站初步运用。
Adhere to the conditions of the station shares of the use of the channel, the introduction of time windows, weights and limits of three parameters, based on the use of ranking theory to build the station runway ranking model. Combining with the actual work process and route arrangement of trains at the station, the heuristic algorithm is used to solve the model and the initial plan of stock channel utilization is obtained. Based on the principle of selection, route arrangement and multi-option optimization, the initial solution of stock utilization is improved, and the improvement plan of stock utilization is obtained. Using the modern flexible theory, a personal-computer interaction interface is set up, the feasibility of the stock channel is taken as the first optimization objective and the balance is the second optimization target. The flexible model of the stock channel utilization is established, and according to the man-machine interactive conversation Solve. The automatic arrangement system of the railway station’s stock channel using the model and algorithm has been initially applied in Guangzhou East Railway Station and Shaoguan Station.
