基于多主体的城市微模拟平台Grid ABGIS研究

Research on Multi-Agent Based Urban Simulation Platform

为了有效集成基于主体的模型(Agent Based Model,ABM)和地理信息系统(Geographical Information System,GIS),将经典地理信息系统的功能从着重宏观地理格局的描述扩展到注重微观行为机制的刻画,作者提出并设计了一个具备网格计算能力的集成化城市微模拟平台---Grid ABGIS。首先回顾了目前城市微模拟研究进展,通过对城市微模拟系统信息过程进行归纳和总结,从软件工程的角度提出了"七步法"城市模拟信息工程的基本框架;其次分析了通用多主体城市模拟软件平台Grid ABGIS的信息处理流程和相应的系统需求;最后对Grid ABGIS的系统结构、对象体系结构、数据模型和城市主体对象模板进行了详细设计,进而实现了一个ABGIS原型系统。

In order to integrate efficiently multi-agent based models （ABM） and geographic information system （GIS） and to promote the performance of computing, this paper tries to put forward a framework of an integrated urban micro-simulation software plafform-GRID-ABGIS, an agent-based GIS with GRID computing. Firstly, this article reviews the chamcteristics of system structures in several classical researches on urban micro-simulation. Then, the authors summary an urban simulation information system by using the skills of software engineering from those researches. Secondly, the paper discusses the information processes of urban micro-simulation applications and analyzes the system requirements of a micro-simulation software platform. Thirdly, it presents a detail design for Grid ABGIS, including the system architecture of Grid ABGIS, the data model of ABGIS and the ABGIS .object architecture. Finally, a series of technological problems in realizing ABGIS prototype are explored.
