摘要
针对当前动车组周转计划在列车运行图“抽线”时所出现的客流适应性差问题,提出考虑客座率偏好的动车组周转计划编制方法。以列车运行线为节点、列车运行线衔接关系为弧构建时空网络,弧的费用用接续时间的函数表示,则一条动车组交路可以表示为时空网络中的一条路径。在考虑动车组接续效率的同时,提出将客座率相近的运行线编至同一条动车组交路的客座率匹配关系,并将其表示为运行线间是否可以接续的一个约束条件,从而将动车组周转计划编制问题转化为一类带特殊约束的最短路问题。设计了基于Cplex的分组求解方法。所生成方案除了满足动车组使用效率优化的传统目标外,客座率相近的运行线被编制在同一条交路中,以适应抽线方式对动车组周转交路的需求。
Aiming at the current problem of poor passenger flow adaptability during the“removing train operation lines”in the train working diagram,this paper proposed the method of compiling the circulation plan for electronic multiple units(EMUs)considering load factors.A space-time network was established with train operation lines as nodes and connection relations between train operation lines as arcs,and arc cost was represented by the function of the connection time,so that an EMU routing could be expressed by a path on the network.While considering the connection efficiency of EMUs,the load factor matching relationship was defined to make train operation lines of the same path with similar load factors and was expressed as a constraint condition of whether train operation lines could be connected.In this way,the circulation plan for EMUs could be transformed into a kind of shortest path problem with special constraints.Based on Cplex,a grouping solution was designed.In addition to meeting the traditional goal of optimizing the efficiency of EMU,the generated scheme also included train operation lines with similar load factors into the same routing to satisfy the need of the“removing train operation lines”for EMU circulation.
