Modeling of manufacturing execution in disperse productive systems using service oriented technique

Markets are becoming independent of geographic barriers and industries are seeking new productive systems (PS) configurations, from centralized to distributed structures, moving their productive plants to countries with energy reserves and low operating costs. To allow the tasks coordination and management in this new distributed structure, it takes advantage of the advances in mechatronics and information technologies, which should assure cooperation between the system parties and between the involved users (clients, operators, managers, etc.). Each part of the disperse PS, which is also a PS, has a high level of operational autonomy. Thus, this kind of system presents new integration and coordination problems which must be overcome to achieve effective implementation. The users of the system require communication frameworks for negotiating the processes involved in production. In this context, this work initially shows a control architecture for users negotiation in a disperse PS. To implement the control architecture, computational models exploring the potential of the Petri net was developed using the production flow schema to systematize the construction of models.
