Analyse et représentation par Bond Graphs des fonctions d'écoulement de flux de produits manufacturés

A manufacturing system is, in certain respects, a net of workstations interconnected by the ways on which the loads flow. In this paper we are analysing this network and we are setting up an « energetic » modelling formalism, based on the canonical pair of variables : number and frequency of loads. This enables us to define the « power » by the flow rate and the « energy » by the number of conveyed products, and to interpret the manufacturing system as a system which is carrying, converting and storing this energy.
