Une approche générique de modélisation spatiale et temporelle : application à la modélisation de la dynamique des paysages

Abstract : Sciences dealing with reality be it related to nature, society or life, use models. Some of these models describe the relations that exist between measurable properties of that reality, without detailing the interactions between its components. Other models describe those interactions from the point of view of the individuals that form the system, in which case the overall behaviour is not defined a priori but observed a posteriori. In both cases, it can be noted that the scientist is often limited in its capacity to describe the structures, especially those spatial, which support the interactions. We propose a modelling approach that can be considered intermediate, where the system is studied by examining the nature of the interactions involved and the graph structures needed to support them. By unifying the description of spatial, functional, social or hierarchical relationships, we attempt to lift constraints induced by the form of spatial representation that are often chosen a priori. The basic concepts of this approach have been formalized, and were used to define and build a domain specific language, called Ocelet. The tools related to the implementation of the language have also been developed and assembled into an integrated modelling and simulation environment. It was then possible to experiment our new modelling approach and the Ocelet language by developing models for a variety of dynamic landscapes situations
