JLB... a model by Jean-Luc Bonnefoy
Abstract of the paper
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:
The short film (see animated gif on top) presents one simulation of 250 steps (21 years, with 1 step = 1 month), starting with a community of 40 shepherds. The periodicity to update the thresholds and to mark up the forests is 10 years.
The following graphes present the evolution of the landscape and the wood lands:
Evolution of the number of cells in forest
Evolution of the number of wood lands (agregates of forest)
Evolution of the mean size of the wood lands
Map of the landscape at step 2000 (months)
(in dark green, the marked forests)
