摘要:

在阶段配流计划给定的条件下,合理安排不同去向的车流到分类线上,对阶段 计划和调车作业计划之间的协调、提升编组站作业效率具有重大意义.本文在分析分类线 不同运用方式的基础上,以最小化整理线数量和出发列车编组连挂次数为目标,考虑分 类线的能力、出发列车占用分类线数量等约束,构建了分类线运用的0-1 整数规划模型; 考虑到分类线运用计划编制对时效性的要求,设计禁忌算法求解模型,并与IBM ILOG CPLEX进行对比分析.最后,算例验证了模型与算法的有效性,并分析了分类线的数量、 长度及站存车等因素对分类线运用方案制定的影响.

Abstract:

Classification track assignment decides how to build each outbound train on different classification tracks in hump yard based on the railcar connection plan and plays an important role in rail yard. In this paper, an optimization model for classification track assignment is proposed, which aims to minimize the number of mixed tracks and pullback operations. The constraints of this model mainly include track capacity constraint, and track number constraint for each outbound train. Tabu Search algorithm is proposed to solve the model and the result is compared with IBM ILOG CEPLEX. As last, a numerical example is presented to valid the proposed model and algorithm. The result shows that the classification track assignment is influenced by the number and the length of classification tracks, the railcar connection plan and the layout of rail yard.

Key words: railway transportation, classification track assignment, mixed track, Tabu search, hump yard
