Situation and development of railway transportation system simulators

Abstract

回顾了铁路运输系统模拟的发展现状和发展趋势 ,简要分析并评述了几个国外常用的铁路仿真系统的特点、主要功能和应用领域 ,探讨了铁路模拟研究中常用的模糊集理论与多智能体技术 .并从我国铁路运输的实践出发 ,分析了铁路模拟器的基本结构和一些关键技术及其在铁路运输研究中的应用 ,包括加强基础数据收集、注重专业知识与计算机技巧的集成、加强可持续模拟框架的论证、注意软件测试以及模拟系统在应用过程中的技术积累等问题 . Reviewing the state_of_the_art and the trend of railway transport system simulation, this paper simply introduces the characteristics and analyzes their functions of several international railway simulators as well as their application areas. It also discusses the structure of a general railway simulator and reviews the methodology, such as fuzzy set theory, multi_agent system and agent_oriented technology in developing such simulators. Based on the practices of Chinese railway simulation researches, the paper advances the key points with their applications to develop a railway simulator from the viewpoint of technical aspect, including traffic data collection, better integration of professional knowledge and computer skills, sustainable framework of simulator, improving documentation and software validation, and more accumulation of technical content.
