ABSTRACT: Due to the models are basic tool of analysis for urban planners and the complexity of the urban growth process, in this paper, a model was developed based on CA, AHP and GIS for simulation of this phenomenon. At first, the factors affecting urban growth were determined and their weights were calculated by AHP. Then, a standalone CA was developed and simulation was performed for 2012 based on the data of 2005. By calculating the Kappa coefficient the accuracy of the model was demonstrated. The results suggested that the combination of indicated models can provide an appropriate tool for urban planners to profoundly analyze and predict urban growth process.

Keywords: urban simulation, CA, AHP, GIS, 8th and 12th municipal districts of Isfahan
