城市轨道交通列车编组方案研究综述

Research Review on Marshalling Scheme of Urban Rail Transit Trains

城市轨道交通是现代城市重要的公共交通方式,而列车编组优化则是提高城市轨道交通效率、降低运营成本的重要手段。文章对现代城市轨道交通列车编组的优化研究进行了综述分析,首先,介绍了列车编组的概念及其对运营管理优化的重要性,主要是关于目前存在的固定编组、大小编组、灵活编组、虚拟编组等几种编组模式的及其特性差异。其次,介绍了列车编组的优化模型,主要对现有列车编组相关研究文献中模型的目标函数、约束条件和模型求解方法等几个方面进行分析和研究。基于现有研究,发现现有学者并未过多涉及合理的列车编组与节能环保之间的关系,因此,文章提出将节能、环保等角度作为目标函数之一,并充分利用人工智能算法或启发式算法调用求解器的精确算法求解模型。

Urban rail transit is an important public transportation mode in modern cities,and optimizing train marshalling is a crucial means to improve its efficiency and reduce operational costs.This paper presents a comprehensive analysis of the optimization research on train marshalling in modern urban rail transit.Firstly,the concept of train marshalling and its significance for operational management optimization are introduced,focusing on several existing marshalling modes,including fixed marshalling,variable marshalling,flexible marshalling,and virtual marshalling,along with their characteristic differences.Secondly,the optimization models for train marshalling are discussed,analyzing the objective functions,constraints,and solution methods found in existing literature.Based on the existing research,it is noted that scholars have not extensively explored the direct relationship between reasonable train marshalling and energy conservation and environmental protection.Therefore,this paper proposes to include energy conservation and environmental considerations as one of the objective functions,and to fully utilize precise algorithms by employing artificial intelligence or heuristic algorithms that call upon solvers to solve the model.
