This article proposes a Fuzzy Recurrent Synchronized Petri Networks (PNetSinFREC), dedicated to implementing the recurrent appearance of the functions of monitoring-decision. The proposed instrument improves a previous proposal because it proposes modeling the decision function in both autonomous and non-autonomous hierarchical systems. PNetSinFREC integrates fuzzy logic in modeling temporal aspects of the occurrence of monitored events. We propose two types of structural systems decision: hierarchical autonomous system and hierarchical distributed non-autonomous system. On each level there are events with equal probabilities of occurrence I detection. Proposed typology provides a recurrent behavior to the horizontal firing of the networks, which allows the detection of the occurrence I persistence of the external events monitored. It proposes an application for monitoring of the PNetSinFREC in a distributed system for production I consumption from renewable energy with photovoltaic solar panels. ©2009 ACA.
