城市轨道交通CPSS平台构建研究

城市轨道交通系统同时涉及工程复杂性和社会复杂性,呈现动态性、开放性、交互性、自主性等特征,是社会物理信息系统(Cyber-physical-social system, CPSS)的典型代表,传统的仿真技术难以对其进行全面的研究和分析.本文研究并构建了城市轨道交通CPSS平台(包括物理系统模型、社会系统模型、Cyber系统模型),建立相应的计算实验平台和综合评估系统,描述其详细功能.通过CPSS平台可进行各种极限和常规实验,对城市轨道交通在正常情况下的评估优化和在突发事故下的应急管理进行研究,提高对城市轨道交通的建模、评估、分析和优化能力,还可为运行方案评估与规划、城市轨道交通设计、应急预案评价与优化、人员培训等方面提供技术支持.

Construction of CPSS Platform of Urban Rail Transit System

The urban rail transit (URT) involves engineering complexity and social complexity simultaneously, and presents such characteristics as dynamicity, openness, interaction, and autonomy. It is a typical representative of cyber-physical-social system (CPSS) and is difficult to be researched and analyzed by traditional simulation technologies. This paper intends to study and construct a CPSS platform of URTs (CPSS-URT), which includes physical system model, social system model, and cyber system model, as well as its corresponding computational experiment platform, and a comprehensive evaluation system. Then, its functions are described in detail. The CPSS-URT can carry out various limit and routine experiments, for evaluation and optimization of URTs under normal conditions and the emergency management under sudden accidents, so as to improve the ability to model, evaluate, analyze, and optimize URTs. It can also provide technical supports for evaluation and planning of operational programs, URTs' design, evaluation and optimization of emergency plans, and personnel training.
