Abstract: In this thesis, we propose a generic method to develop 2D and 3D multiagent geosimulation of complex behaviors (human behaviors) in geographic environments. Our work aims at solving some problems in the field of computer simulation in general and the field of multiagent simulation. These problems are are: - The absence of methods to develop 2D-3D multiagent simulation of phenomena in geographic environments. - The absence of gathering and analysis techniques that can be used to collect and analyze spatial and non-spatial data to feed the geosimulation models (input data) and to analyze data generated by geosimulations (output data). - The absence of a ‘realistic’ and ‘useful’ geosimulation prototype of customer’s shopping behavior in a mall. The main idea of our work is to create a generic method to develop 2D and 3D multiagent geosimulations of phenomena in geographic environments. This method contains ten steps, which are summarized as follows: The first three steps of the method aim to (1) define the geosimulation users’ needs, (2) identify the characteristics of the phenomenon to be simulated, as well as its environment, and (3) create the geosimulation models using the multiagent paradigm. The fourth step aims to select the simulation tool/environment/language that is used to develop the geosimulation. In step five, we collect the data which feeds the geosimulation models. In this step, we analyze the collected information in order to define some patterns of the behaviors of the phenomenon to be simulated. In the sixth step, we develop the geosimulation prototype, on the selected simulation platform, using the collected data. In step seven, we collect information about the course of the simulation, once again using the multiagent paradigm. In this step, we deal with the non-spatial and spatial data, generated by the simulation using several analysis techniques: Classical or traditional analysis techniques, our own analysis technique/tool, and the OLAP (On Line Analytical Processing) and SOLAP (Spatial On Line Analytical Processing) technique. In order to ensure the correctness of the simulation models, as well as to enhance the confidence of the simulation users, we need to verify and validate the simulation models. The verification and validation are the purpose of the eighth step of our method. In the ninth step, we test and document the simulation, while in the last step users can use the multiagent geosimulator in order to make efficient spatial decisions about the phenomenon to be simulated or about the configuration of the simulated environment. The main contributions of this thesis are: - A new method to develop 2D-3D multiagent geosimulations of complex behaviors (human behaviors) in geographic environments. - Some models dealing with the shopping behavior in a mall: an initial version of the shopping behavior model based upon a large literature review, an initial version of the multiagent model which is independent of the tool used to execute the simulation, and an agent-based model created according to the selected platform used to develop the geosimulation. All these models are related to the individual shoppers and to the simulated environment representing the mall. - An illustration of the method using the shopping behavior in a mall as a case study and the Square One mall in Toronto as a case test. This gave birth to a ‘realistic’ and ‘useful’ geosimulation prototype called Mall_MAGS. - A new survey-based technique to gather spatial and non-spatial data to feed the geosimulation models. - A tool to digitalize the spatial and non-spatial gathered data. - A new agent-based technique to collect output data from the geosimulation prototype. - A new analysis technique and tool to analyze spatial and non-spatial data generated by the geosimulation. - A coupling of the OLAP (On Line Analytical Processing) and SOLAP (Spatial On Line Analytical Processing) analysis techniques with the shopping behavior geosimulation prototype in order to explore and analyze the geosimulation outputs.
