JLB... a model by Jean-Luc Bonnefoy

Abstract of the paper

This paper demonstrates that multi-agent systems have the capacity to model a region in all its complexity. An example is developed to show that these tools are not only capable of spatializing and distributing the behaviour of individuals, but above all, that they allow individuals to integrate different perceptions of space as well as the constraints imposed on them by a community. A dialectic is established between individuals, spaces and society, which is used to simulate a region using clearly defined social representations and spatial practices, which are suitable for testing our geographical theories and hypotheses.

Presentation of the model

The UML diagrams below have been created with two software ingineer tools : Vision (for the class diagram) and Rose (for the others).

The UML class diagram, describing the static structure of the model in the implementation view.

The following UML sequence diagram, describing the dynamic of the model main step :

The following UML sequence diagram, describing the dynamic of the agent step :

The following UML state diagram, describing the states of the cells :

The following UML activity diagram, describing the sphepherds activities:
