摘要: 中欧班列大多开行“点对点”直达列车,这需要较长集结时间来满足编组数量,导致运输时效性大幅下降。对此,本文将直达模式与集结模式引入中欧班列,并开展开行方案与运行图联合优化研究。针对运输成本低与运输时间短的双目标优化,借助于ε约束法来寻求双重目标的帕累托前沿,并设计嵌入CPLEX的启发式算法框架。以中欧班列西通道上7个车站和20票货物为背景,对本文模型的可行性与有效性进行验证。结果表明:降低中欧班列的运输成本需要以牺牲运输时间为代价,开行直达与集结班列分别有助于降低成本和缩短时间。“集结+直达”模式相比全直达模式,虽然增加了9.6%运输成本,但却缩短了20.3%的运输时间。相比于运行图联合优化,开行方案单独优化的结果无法满足列车接续以及运输时限约束。

Abstract: The point-to-point direct transport is the major operation mode of the China-Europe Railway Express. However, the direct transportation mode needs long assembly time for vehicles grouping, which leads to decreased operational efficiency. This paper proposed the combined transportation modes of direct and assembly for the China-Europe Railway Express, and conducted the joint optimization for operation plan and train diagram. The ε-constraint method was used to obtain the Pareto front with the dual-objective of low transportation cost and short transportation time. The heuristic algorithm framework was embedded with CPLEX. The feasibility and effectiveness of the proposed model was verified through the case studies with 7 domestic stations and 20 cargoes in the China-Europe Railway West Line. It was found that reducing the transportation cost of China-Europe Railway Express would be at the expense of its transportation time. The direct and assembly transport modes would help to reduce the cost and shorten the time. The transportation cost of assembly and direct mode increased by 9.6% compared to only using the direct mode, while the transportation time decreased by 20.3%. Compared to the results of joint optimization, the train diagram obtained through operation plan optimization alone cannot meet the connection constraint and time limit for the train operations.
