摘　　要：在中老铁路既有技术运输条件下,以保证客运服务能力为前提,为提高中老铁路货物运输收益,研究提出考虑中老双方作业时间不匹配的货物列车开行方案,以确定货物列车开行的始发终到站、开行数量、编组内容、编组辆数和开行时段等内容。基于中老铁路通道运输作业特点和市场需求特征,以通道货物运输收益最大化为目标,考虑车流选择径路唯一、区段通过能力、列车编组辆数及运到时间等约束,构建中老铁路通道货物列车开行方案优化模型,并采用遗传模拟退火算法求解。以中老铁路跨境通道下行方向相关数据进行算例求解分析,结果显示研究中的优化模型能够在满足运输需求的同时提高货物运输收益,并合理分配列车开行时段,验证了模型及算法的有效性。Under the existing transportation conditions of China-Laos Railway,with the premise of ensuring passenger service capacity,this study proposed a freight train operation scheme to enhance freight transport revenue of China-Laos Railway,which considered the mismatch in operation time between China and Laos.The scheme targeted determining departure and destination stations,operation frequency,train composition,number of wagons per train,operation time slots,and other parameters.Based on the transportation characteristics and market demand of the China-Laos Railway corridor,an optimization model for the freight train operation scheme of the China-Laos Railway corridor was developed to maximize freight transport revenue,with constraints considered,such as unique route selection,passing capacity in section,number of wagons per train,and arrival time.The genetic simulated annealing algorithm was used to solve the model.A case study,utilizing data from the downward direction of the China-Laos Railway corridor,was conducted.The results show that the proposed optimization model can meet transportation demands while increasing freight transport revenue and can allocate operation time slots reasonably,validating the effectiveness of both the model and the algorithm.
