为了有效支持轨道交通突发事件的应急管理,构建面向轨道交通应急管理的信息集成及应用平台,集成各种分布的异构数据,并根据不同决策需求进行分析以快速响应决策者的需要.首先讨论城轨交通应急管理流程及信息流；再对平台的三个主要模块的结构和功能进行分析:一是基于XML的分布式异构数据集成模块；二是基于应急事件分级以选择不同挖掘算法的数据挖掘模块；三是基于城轨交通应急决策模型组合链构建的决策支持模块；融合这三个模块得到的信息处理平台,可以在实现各种分布异构应急数据集成的基础上,满足轨道交通应急决策实时性要求及解决应急管理各阶段决策模型契合度差等问题.最后利用一个实例详细说明平台信息集成及应用过程.%To effectively support urban rail transit emergency management, this paper develops an information integration and application platform that integrates all the heterogeneous distributed incident data and can rapidly respond decision request according to different decision makers. First, the paper introduces the management and data process of urban rail transit emergency management. Then, it analyzes the structure and function of the information integration and application platform that consists of three major components. The first component is a high-level data integration module based on the XML. The second component is a data mining module that selects different data mining methods according to differentiated service mechanism. The third component is decision-making module that based on the emergency decision model chain building method. The platform framework integrated from the three components can meet realtime decision-making and solve the problem of poor decision-making model fit based on integrating all theheterogeneous distributed incident data. Finally, a case is used to illustrate the proposed platform in detail.
