客运专线综合运营调度系统Agent结构和规则描述

为提高客运专线综合运营调度系统的智能性, 采用智能体(Agent) 技术, 将运输调度决策过程看作是Agent之间的协商过程, 建立了客运专线综合运营调度系统的多智能体(MAS) 体系结构。将列车运行调度子系统、动车组调度子系统、牵引供电调度子系统和车站分别抽象为Agent, 所有Agent构成了Agent社会, 给出了Agent社会规则。在体系结构的基础上, 给出了二路四层垂直型结构的公司行调Agent结构和反应式车站Agent结构, 并阐述了其工作原理。仿真结果表明: 在遵循社会规则下, Agent能在10s内调整列车运行计划, 5s内选取调度预案, 因此, MAS体系结构可行, 能够提高运营调度系统的智能性。

Description of architecture and rules of integrated operation dispatch system for passenger dedicated line

In order to improve the intelligence of the integrated operation dispatch system for passenger dedicated line,using agent technology,the architecture of multi-agent system(MAS) was presented by regarding the process of transportation dispatch as the negotiating process among agents. Train traffic control subsystem,motor train unit dispatch subsystem,the power supply subsystem of electric traction and railway station were abstracted into agents respectively,and all these agents constituted an agent society,in which social rules were given. Based on MAS architecture,the structure of company's train traffic control agent was given,which was 2-way-4-layer vertical architecture,railway station agent architecture was given,which was reactive one,and their running principles were desicribed. Applied result shows that,for agent,the time of adjusting operation plans on train is less than 10 s,the time of choosing dispatch preplans is less than 5 s,so MAS architecture is feasible and has high intelligence under the control of the rules. 4 figs,7 refs.
