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。
In order to improve the intelligence of the comprehensive operation scheduling system of passenger dedicated line, this paper adopts Agent technology to consider the decision process of transportation scheduling as the negotiation process among Agents, and establishes MAS (Multi-Agent) Architecture. The train operation dispatching subsystem, the EMU dispatching subsystem, the traction power supply dispatching subsystem and the station are respectively abstracted as an Agent, and all Agents constitute an agent society, and an Agent social rule is given. Based on the architecture, this paper gives the company agent-transfer agent structure and reaction station agent structure of two-way four-storey vertical structure, and expounds its working principle. Simulation results show that under the social rules, Agent can adjust the train operation plan within 10s and select the scheduling plan within 5s. Therefore, the MAS architecture is feasible and can improve the intelligence of the operation dispatch system.
