Un outil de modélisation pour les systèmes physiques complexes

An examination of a particular Petri Net structure has been carried out. The characteristics of this Petri Network are in good agreement with classical tools used in simulation. A few notions like attractors, attractor bassin or disturbance of a system are introduced here for Petri Nets. It appears that the Petri Net can be a good tool for physicists and automaticians
