基于MAS的列车运行调整方法

针对列车运行调整问题,运用多智能体系统(MAS)技术,将列车运行调整方案的制定过程抽象为多用户(列车)对车站股道和区间线路等共享资源的占用预约过程,在此基础上建立智能体模型。车站和区间被抽象为资源Agent,列车被抽象为用户Agent,由资源Agent和用户Agent组成多Agent系统,Agent之间采用合同网协议进行协作。列车运行调整方案由Agent之间的分布式自主决策和相互协作产生。协作过程中的数据通信采用KQML标准设计,并增加消息等级,以提高通信和系统的效率。仿真实验表明,采用基于MAS的列车运行调整方法是可行的。

MAS-Based Method for Train Operation Adjustment

In allusion to the issue of train operation adjustment and by adopting multi-agent system(MAS),the process for establishing the scheme of train operation adjustment is abstracted into the process for multi-user(trains) occupancy reservation of such shared resources as station track and section track,etc.On this basis,intelligent agent model is built.Station and section are abstracted as resource agents.Train is abstracted as user agent.Thus train agent,station agent and section agent constitute multi-agent system.The cooperation between agents is carried through contract net protocol.The scheme for train operation adjustment is generated from the distributed self-decision of/between agents and their joint cooperation.Data communication during the cooperation process is designed according to KQML standard.Message degree is increased to improve the efficiency of communication and system.Simulation results indicate that MAS-based method for train operation adjustment is feasible.
