STRUCTURED, MODULAR DESIGN FOR CONTROL-SYSTEMS OF FLEXIBLE MANUFACTURING PRODUCTION

In this paper a structuration tool is presented which allows rigorously and systematically the procedural part of the control system of flexible manufacturing systems to be built. This tool allows the producing of a control graph (Coloured Structured Petri Nets) where the parallelism and the concurrency of the system are shown. Thus we had care for the bigger flexibility of the creation of a such graph. In this way, we propose a set of structuration primitives based on a functional analysis of the initial model (called << Pregraph >>) of the production system. Moreover, the automatization of the structuration approach allows time during the design step to be spared and brings a best reliability owing to the logical consistency of the pregraph.
