铁路装车地直达列车组织研究

A Study on the Organization of Direct Train from Loading Station

铁路装车地直达列车作为一种高效的车流组织形式,可以提升铁路货物运输效率和服务质量,对于增强铁路运输市场竞争力具有积极作用。分析铁路车流的3种典型运输模式,以所有货车的总运输时间最短为优化目标,建立装车地直达列车编组计划优化的线性0-1规划模型,利用MATLAB软件求解。通过算例分析,验证了在装车量较小的装车站或装车量较大而无法满足整列出车条件的装车站组织开行装车地直达列车的合理性。

As an efficient traffic flow organization, the direct train from loading station improves the efficiency and service quality of railway freight transport and plays a positive role in enhancing the competitiveness of railway freight transport. This paper analyzes three typical transport modes of railway traffic flow, takes the shortest total transport time of all freight trains as the optimization objective, establishes linear 0-1 programming optimization model for the marshalling plan of direct train from loading station, and solves it with MATLAB software. The example verifies the rationality of organizing the direct train from loading station where the loading capacity is small or large, which cannot meet the conditions of the whole train.
