Study on Optimizing Model of Empty Wagon Distribution in Railway Station

空车调配是铁路车站运输组织工作的重要内容。参考传统运输问题模型,结合车种代用、分阶段实施、重点任务优先完成、摘挂作业机车消耗等实际问题,首先提出车站空车调配的确定性数学模型,然后考虑车流推算数据与实际生产之间的误差,综合目标函数与作业点空车供应量的不确定性,建立车站空车调配的模糊规划模型,提出模型求解的思路与方法。

Empty wagon distribution is an important job of the traffic organization in railway station. This paper refers traditional model about transportation problem, and take several practical factor such as substitution of wagon types, implementation in phases, priority of key task, consumption produced by work of detaching and attaching into consideration, firstly,a certain model of empty wagon distribution in railway station is devised. Then, taking the data deviance between prediction and reality into consideration and incorporating the fuzzy goals and fuzzy constraint of empty wagon supply, fuzzy programming model of empty wagon distribution in railway station is formulated. Then, on basis of analyzing model＇s complexity proposes thought and method of solving the model.
