- Abstract:
-
The Chinese economy grew rapidly for more than 20 years, promoting rapid urbanization. New cities emerged and great changes took place in old cities. Population changes complicated city planning, infrastructure construction, housing, and environmental preservation. A model simulating this population transformation was built merging methods from Geographical Information Systems, Multiagent Systems and Stochastic Processes. First an efficiency function was proposed to represent the effectiveness of a resource within the GIS. Second, a multiagent system was designed and implemented, with agents representing ground segments and profits acquired after that. Third, static attributes and dynamic behaviors of agents were discussed. To model the uncertainty of urban development better, a behavioral mode was designed based on a stochastic process, consistent with macrolevel characteristics of the agent. The combined system and its implementation in a computer were then discussed. Finally experiments, using data from Pudong District of Shanghai, were run and analyzed. This urban evolution model can be adapted to more types of research and owes its good performance to modularity and scalability.
