摘要
作为铁路车流组织的主要形式之一,分组列车具有减少货车集结时间、减轻途中调车作业负荷和加速车辆周转的显著作用,但由于其复杂性和特殊性,国内学者对其组织优化进行研究的不多。本文首先阐明了分组列车的开行意义和组织特点,然后基于已有的较成熟的单组列车编组计划优化理论,分别对产生分组列车的两种情况(即合并单组列车为分组列车和衔接单组列车为分组列车)从车小时节省角度做了详细的技术效益分析。在引入阶跃函数的前提下,提出了技术站分组列车编组计划的0-1规划模型。模型以是否开行分组列车所产生的技术效益最大化为目标,并兼顾分组列车的技术作业条件。最后,通过数值算例的演算,验证了模型的有效性,并归纳了模型的特点及适用范围。
As an important mode of railcar operation, multi-block trains play the role of reducing accumulation time, cutting down shunting on the way and speeding car movement. However, the complexity and particularity attract few domestic specialists and scholars. So, this paper firstly expounds the meaning and characteristics of multi-block trains. Then based on optimal theories of the train formation plan of one block trains, car-hour savings of two cases in which multi block trains are formed respectively are analyzed in detail. With utilization of the step function, the 0 1 programming model is constructed to optimize the train formation plan of multiblock trains at technical service stations. The objective is to maximize the technical benefit, which is regarded with the working conditions of multi block trains. Finally, the paper gives a numerical example, which proves the effectiveness of the model, and interprets its speciality and applicability.
