Formation Mechanism Analysis Of Shanghai Destination Circle On Agent-based Simulation

At present,tourism has become an important part of the national economy.Studying the destination circle is one of the important means to promote regional tourism cooperation and the development of tourism.The paper takes human-environment interactions as background, destination circle as example.Combined with agent-based simulation technology and GIS technology,this paper analyses the formation mechanism of destination circle from a perspective of tourists,and try to analyses the impact of tourists on the formation mechanism of destination circle from the aspect of the factors that effects the behavior of tourists.There are six chapters in this paper.The 1st chapter is the Introduction,mainly summarizes current situation and shortages of the study on destination circle and introduces the concept of agent and the modeling methods based on ABS.Then analyzes the advantages of ABS based modeling methods on geographical issues resolving.In this chapter we propose a research idea that discusses the formation mechanism of destination circle combining the method of ABS.In 2nd chapter,we first overview the impact of the tourists' behavior and the main factors affecting the traveling behavior of tourists to elaborate the model of the behavior of tourists, which is the focus of this paper;Then we introduce the Spatial Interaction Model to provide a theoretical basis for travel behavior;Finally,we present the classification methods of tourism resources to provide tourists a criterion for tour destination choice.In 3rd chapter,we build a system of destination circle model.First of all,we create a tourism region to provide a space for tourists;Then we design the tourist as Agent and add tourist attributions to the agent.After that,we constrain the behavior of tourist agent through time model and cost model.Finally,we design the behavior patterns of the agent so as to set the rules for corresponding behaviors.The 4th chapter is mainly about the model system of destination circle.First,System Requirements Analysis is applied on several aspects,such as the comprehensive requirements of the system,data requirements for analysis,exporting system and correcting system.Secondly,we design corresponding function module of the system based on the requirements above.Finally,we realize each module of the system using MO components in VB platform so as to realize the whole destination circle model system.In the 5th chapter,based on all factors of the impact on tourists,the destination circle model system is applied to simulate different scenarios and get different simulation results with which we discuss the main factors and characteristics affecting the destination circle.The conclusion is that time and money have a direct impact on travel behaviors and a certain effect on the size of destination circle.Without limitation of time and money,tourist will have different selections because of their own personal preferences and tour-utility.Analyzing from the key city,we can find that the number of tourists traveling around the cities beside key city in certain destination circle will increase by raising the market share.In the final chapter,the conclusion of the paper is summarized.The author also points out the disadvantages and future works for the dissertation.
