摘　　要：重载铁路始端技术站在重载铁路线网中拥有重要的地位和作用,优化始端技术站重载列车组合策略,可有效提高线路运输效率。针对技术站节能列车组合策略优化问题,首先考虑到达列车组合唯一性、接入货运量、运行图能力等约束的基础上,以一天内从技术站发出的各类型列车的运行成本最小为目标,结合组合站内整体作业流程,构建始端技术站列车组合优化的整数规划模型。然后分析确定列车开行成本评估指标,并基于层次分析法量化成本指标权重。最后,以神池南站为例进行分析,研究其列车组合方案问题,对计算结果的分析表明,所给出的重载列车始端技术站组合优化模型简单而实用。The start-end technical station of heavy haul railway plays an important role in the heavy haul railway network.Optimizing the combination strategy of heavy haul trains in the start-end technical station can effectively improve the efficiency of line transportation.Aiming at the optimization problem of energy-saving train combination strategy in technical station,firstly,based on the constraints of the uniqueness of arrival train combination,the access freight volume and the capacity of train diagram,the integer programming model of train combination optimization in the beginning technical station is constructed by combining the overall operation process of the combination station with the goal of minimizing the operation cost of various types of trains issued from the technical station in one day.Then,the evaluation index of train operation cost is analyzed and determined,and the weight of cost index is quantified based on analytic hierarchy process.Finally,taking Shenchinan Station as an example,the problem of train combination scheme is studied.The analysis of the calculation results shows that the combination optimization model of the technical station at the beginning of the heavy haul train is simple and practical.
