客运专线综合运营调度系统agent知识描述

Knowledge Description of agent for the Integrated Operation and Dispatching System of Passenger Dedicated Line

根据客运专线综合运营调度系统结构,为建立系统知识库,将客运专线的运输环境分为静态环境和动态环境。静态环境包括车站顺序关系、站场配置和列车运行计划。动态环境包括列车、车站、线路和自然环境。按照知识工程思想和anget理论,采用一阶谓词逻辑和映射分别对静态环境和动态环境进行形式化描述,给出推理规则的形式化描述。在仿真系统中推理规则采用IF-THEN形式存储,agent采用数据驱动的方式进行推理。仿真结果表明,采用一阶谓词和映射对agent的知识进行描述是可行的。

Based on the architecture of the integrated operation and the dispatching system for Passenger Dedicated Line（PDL）,the transportation environment of PDL is divided into the static environment and the dynamic environment in order to construct system knowledge base.The static environment includes the relations among stations,the station yard configuration and the train operation plan,and the dynamic environment includes the train,station,natural environment and railway line information.According to the knowledge engineering idea and agent theory,the static and dynamic environment is respectively described formally using the first-order predicate logic and the mapping,and the reasoning rules are given as well.In the simulation system,the knowledge on the reasoning rule is stored using IF-THEN,and the agents adopt the data-driven method to reason. The simulation result shows that it is feasible to describe the agent＇s knowledge using the first-order predicate logic and mapping.
