【摘要】：全自动运行系统(Fully Automatic Operation,简称FAO),是以现代信息技术提升运行服务水平为目的的新一代城市轨道交通系统,已成为国际公认的主流发展方向之一。高等级自动化系统的应用会使人机功能得到重新分配,特别是当运营中出现紧急状况,运营单位采取的应急处置相比与传统大有不同,因此需要重新研究适合FAO的应急处置策略。应急处置作为轨道交通运营过程中的重要环节,处置策略通常需要各专业根据经验联合攻关制定,但由于城市轨道交通的复杂性,进行真实应急场景演练的难度较大,因此需要构建特定的仿真环境进行策略验证。针对于此需求,本文将根据全自动运行系统应急处置特点,选用合适的方法建立应急处置抽象模型,完成应急处置仿真平台的开发,并设计科学的评价体系,实现对应急策略的验证分析。本文具体研究工作如下:(1)根据全自动运行系统的结构特点,分析系统设备和组织人员架构的变化,理解全自动运行系统下轨道交通的运营过程,深入提炼具有仿真意义的应急场景,明确仿真的内容和需求。(2)研究多智能体(Multi-Agent System,简称MAS)建模方法,将应急处置中的参与对象抽象成中心调度、乘客、列车、现场处置员和线路五类Agent,并构建中心、车站和列车三层仿真架构。基于相应的基础原理,对每一类Agent的感知、决策和行动等属性进行定义,确定Agent之间的交互方式和内容,最终完成全自动运行系统应急处置仿真模型的构建。(3)基于MAS模型和北京燕房线数据,利用Anylogic仿真工具开发全自动运行系统应急处置仿真平台。平台具有良好的人机交互界面,可实现控制应急进程,动态跟踪交互信息,三维显示处置过程和关键数据管理的功能。(4)结合仿真平台的输出结果,对指标进行具体定义与量化,利用层次分析法构建全自动运行系统应急处置策略评价体系。最后以列车区间迫停场景为例,分析应急策略,并结合评价结果为运营提供决策支持和建议。
[Abstract]:Automatic operating system (Fully Automatic Operation,) is a new generation of urban rail transit system, which aims at improving the level of operation service by modern information technology. It has become one of the internationally recognized mainstream development directions. The application of high-grade automation systems will result in the redistribution of man-machine functions, especially when there is an emergency in operation, and the emergency disposal taken by the operating unit is quite different from the traditional one. Therefore, it is necessary to re-study the emergency response strategy suitable for FAO. Emergency disposal is an important link in the operation of rail transit. The disposal strategy usually needs to be worked out according to the experience. However, due to the complexity of urban rail transit, it is difficult to carry out real emergency scene drills. Therefore, it is necessary to build a specific simulation environment for policy verification. In order to meet this demand, according to the characteristics of automatic operation system emergency disposal, this paper will select appropriate methods to establish the abstract model of emergency disposal, complete the development of emergency disposal simulation platform, and design a scientific evaluation system. Implementation of the emergency strategy validation analysis. The specific research work of this paper is as follows: (1) according to the structural characteristics of the automatic operation system, the changes of system equipment and organization personnel structure are analyzed, and the operation process of rail transit under the automatic operation system is understood. The contents and requirements of simulation are clarified. (2) the modeling method of Multi-Agent System, (MAS) is studied to abstract the participants in emergency management into central dispatching, passengers, trains, etc. Field handlers and line five types of Agent, and build the center, station and train three-tier simulation framework. Based on the corresponding basic principles, the perception, decision and action attributes of each Agent are defined, and the interaction mode and content between Agent are determined. (3) based on the MAS model and the Beijing Yanfang line data, the Anylogic simulation tool is used to develop the simulation platform of the automatic operation system emergency disposal. The platform has a good man-machine interface, can control the emergency process, dynamically track interactive information, three-dimensional display and disposal process and key data management functions. (4) combined with the output results of the simulation platform, the specific definition and quantification of the indicators are carried out. The evaluation system of emergency management strategy of automatic operation system is constructed by AHP. Finally, the emergency strategy is analyzed with the example of train interval forced stopping scene, and the decision support and suggestions are provided for the operation combined with the evaluation results.
