Teoria dos jogos aplicada à tomada de decisões em processos flexíveis de manufatura

Abstract

Supervisory Control Theory (SCT) is an approach that allows to automatically synthesize controllers for industrial processes, which behave robustly, without blockings and according to a set of pre-specified requirements. Despite its theoretical formulation, the SCT directly does not assign flexibility to the resulting control systems. The SCT enables, at each state, a set of possible events, but does not allows to decide about choices and priorities inside this set. As such characteristic predominates and guides modern flexible manufacturing systems, it is necessary to enrich the SCT with new structures that allow addressing it, thus making it applicable to the current concept of industrial control. This paper approaches a flexible manufacturing process as a turn-based game. In this way, techniques and structures from the Game Theory are used as a method for decision-making on flexible processes, allowing to change the production sequence dynamically.
