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 / detection. Proposed typology provides a recurrent behavior to the horizontal firing of the networks, which allows the detection of the occurrence / persistence of the external events monitored. It proposes an application for monitoring of the PNetSinFREC in a …} }
