基于GIS与Multi-Agent System的景区游客空间行为模拟系统

基于GIS与Multi—Agent system技术的景区游客空间行为模拟系统（Tourists’Spatial Behavior Simulator，TSBS），可以对游客在景区的空间移动行为进行微观仿真，实现对景区每个游客的空间位置、行为状态变化的跟踪分析．TSBS构造众多具有与游客同样环境感知能力、目标选择模式、行为决策模式的Agent，模拟游客空间行为，用“路段”、“道”、“节点”、“片区”对景区环境进行表达．TSBS由虚拟时钟控制，时钟每增加一个步长，系统计算所有Agent下一时刻的状态，计算结果存入Agent状态数据库．TSBS同时提供了指标分析、可视化分析等工具实现对模拟结果的分析．TSBS采用server／client的计算模式，可以将局域网甚至Internet作为其计算平台．研究表明，TSBS可以作为景区规划与管理的有效工具．

A Tourists' Spatial Behavior Simulator Based on GIS and Multi-Agent System

TSBS is a tourists' spatial behavior microscopic simulator based on Multi-Agent system and GIS.By TSBS,the location,state and travel cost of each visitor can be tracked,analyzed and predicted.In TSBS,visitors' spatial behaviors are simulated by(agents),which have the same cognitive ability to the environment,the destination selection mode and the decision mode of visitors.Touristre sort space is represented by four elements: segments,lanes,nodes,and areas.The simulation process of TSBS is controlled by the simulation clock.The agents' states are updated at every clock step.All these results will be recorded in the agent status database.In TSBS,visual analysis tools and indicative analyzsis tools are provided to analyze the simulation results.Based on a client/server computation model,the local area network,even the internet,can be used as a computing platform for TSBS.Our researches show that TSBS will be an effective tool for the planning and management of tourist resorts.
