A response to this situation may be based on the dynamics of systems. The latter, initially conceived to provide a method of analysis of management processes, has flourished especially in fields other than industrial management: analysis of urban systems, world models, American economy models… This paper shows that, on the sidelines of this academic boom, the reactivation of the initial spirit inspired by cybernetics has helped to stimulate the modeling of a chain of industrial activity, based on the description and exploration of the dynamic properties of its models. Thanks to the realistic representation of the latter in terms of temporal dynamic flows irrigating an industrial environment considered as a dynamic non-linear system reacting to randomized parameterized perturbations, the simulation described is a powerful means of decisional support, both operational (in the short-term view) and strategic (in the long-term view).}}
