Approche multi-agents de couplage de modèles pour la modélisation des systèmes complexes spatiaux : application à l'aménagement urbain de la ville de Métouia

Abstract : In This work we present an agent-based approach for coupling models in the context of complex spatial systems. The main idea of our approach called Coupling4Modeling is the use of the space as a medium of interactions between the coupling agents to allow them to co-exist and interact according to a set of rules that govern these interactions. By playing the role of coupling factor, space allows coupling agents to exchange data and to observe the results of pragmatic coupling of different models constituting the studied spatial complex sys-tem. This approach consisting in a methodology and an agent-oriented metamodel of coupling. Our metamodel is based on an organizational (AGRE) with holonic architecture that takes into consideration the specificity, autonomy and the calculation scale of each model. This notion of holon allows us to manage the heterogeneity of formalisms and spatio-temporal scales of models. In fact, spatial heterogeneity is managed by the decomposition of the collector and the interpreter agents until reaching the desired level of abstraction. These agents can move from one level to another by adapting the spatial scale of the space to the spatial scale of the model through conversion functions. The temporal heterogeneity is managed by a time agent that will calculate the future date in the execution of the model and a scheduler agent that will schedule these dates following the time scale of the simulation. We take the urban system of Metouia (Tunisia) as an example of spatial complex system, to study with details and to test our coupling4modeling approach. The main goal is to meet the needs of urbanists in terms of decision support in urban planning and to test our coupling approach coupling4modeling.
