铁路客运站到发线运用优化研究

A Study on the Optimization of the Operation of Arrival and Departure Tracks in Railway Passenger Station

合理安排列车占用到发线是编制阶段计划的关键,高效的到发线运用可以提高铁路客运站的工作效率和服务水平。在阐述铁路客运站到发线运用要求的基础上,构建既满足到发线固定使用、又能满足到发线均衡使用及保证行车作业安全的整数规划模型,采用模拟退火遗传算法对模型进行求解。为验证所提算法和建立模型的准确性,依据某客运站8:00—12:00的实际数据,采用建立的模型进行实例分析计算。结果表明,到发线运用方案的优化效果明显,可以为铁路智能化建设提供参考。

Reasonably arranging the occupation of arrival-departure lines is the key of drawing the operation plan and its efficient operation can improve the efficiency and service level of the station.This paper establishes an integer programming model that not only satisfies the fixed use scheme of arrival and departure lines,but also satisfies the balance of arrival and departure lines and ensures the safety of operation by analyzing the arrival and departure of technical trains for passenger trains at passenger stations.The simulated annealing genetic algorithm is used to solve the problem.To verify the accuracy of the algorithm and the model,based on the actual data of a passenger station from 8:00-12:00,the model established by the application is used for instance analysis and calculation.The results show that the optimization effect of the calculated scheme is obvious and it provides reference for railway intelligent construction.
