Abstract :
Presents a framework for a supervisor in balanced automation systems (BAS). The concept of BAS is based on an appropriate technological level considering human factors and highly automated machines. The supervisor not only considers a normal process but also detection and treatment of failures. The framework is based on distributed Petri nets (DPNs). DPNs permit the integration of several modules of Petri nets , where each module represents a particular process such as, normal processes, detection and treatment of failures. A case study of detection and treatment of failure in machining operations is considered, in which, the normal process, the detection and treatment of failures in a BAS are integrated through modules based on DPNs
