摘　　要：铁路项目火车运料运输计划的编制对材料运杂费有直接的影响,进而会影响工程造价。在设计院概(预)算编制部门,能够快速、准确的编制最优的火车运料运输计划对于提高设计单位的工作效率和竞争优势具有重要的意义。本文通过构建铁路网邻接矩阵和运价矩阵,利用改进的Dijkstra定向搜索算法构建铁路项目火车运料运输计划智能搜索方法。经过某新建铁路项目验证,本智能搜索方法能够满足快速、准确的编制火车运料运输计划。The preparation of the railway material transportation plan for railway projects has a direct impact on the material transportation and miscellaneous costs,which in turn will affect the project cost.In the general(budget)budget preparation department of the design institute,it is of great significance to quickly and accurately prepare the optimal train transportation plan for improving the work efficiency and competitive advantage of the design unit.By constructing the adjacency matrix and the freight rate matrix of the railway network,this paper uses the improved Dijkstra directional search algorithm to construct an intelligent search method for the train transportation plan of railway projects.After the verification of a new railway project,the intelligent search method can meet the requirements of fast and accurate preparation of the train transportation plan.
