摘要
编组站工作组织是铁路货物运输关键环节,为提升编组站运营效率,加快货物周转,本研究提出了基于多智能体技术的编组站工作组织仿真模型.结合多智能体仿真技术与编组站工作组织内容,分别设计本务机车、调机、车辆和列车智能体以及其智能呼叫机制、动态进路选择与调度机制以及智能体转换功能,从环境建模和行为建模2个维度构建了编组站智能体仿真模型,实现到达解体列车、自编始发列车和无改编中转列车的作业模拟,并能有效满足编发线列车出发功能以及移动单元的动态进路选择与调度机制,使得仿真模型更贴合编组站的实际工作.最后,通过对实际的单向混合式二级三场编组站进行实例分析,不仅验证了仿真模型及动态进路选择与调度机制的有效性,而且通过实验分析了解编顺序与小运转列车占比对编组站运行效率的影响.结果表明多智能体仿真技术能有效进行编组站工作组织仿真,该仿真模型对于指导编组站工作效率的提升具有重要意义.
Abstract
Marshalling yard operation organizations play a key role in railway freight transportation.To improve the operation efficiency of marshalling yards and speed up the turnover of freight,a simulation model of marshalling yard operation organizations based on multi-agent technology was developed.Combining multi-agent technology and the content of marshalling yard operation organizations,this paper designed the train locomotive,engineering,railcar,train agents and their intelligent calling mechanism,dynamic routing selections,scheduling mechanisms,and the agent transformation function.The agent simulation model of the marshalling yard was constructed from two dimensions of environment modeling and behavior modeling,to realize the operation simulation of inbound disassembled trains,self-marshalled originating trains,and transit trains without reformation,and the dynamic route selection and scheduling mechanism of the moving unit.This way,the simulation model would be more suitable for the pragmatic operation of marshalling yards.Finally,the efficacy of the simulation model,dynamic route selection,and scheduling mechanism was validated through a practical example analysis of a unidirectional hybrid 2-level 3-yard marshalling yard.Moreover,the effect of the disassembly and assembly sequence and the proportion of district transfer trains on the operation efficiency of the marshalling yard was analyzed through experiments.The results illustrate that multi-agent technology can effectively simulate marshalling yard operation organizations,and the simulation model is of great significance for guiding the improvement of the operation efficiency of the marshalling yard.
