Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Shared use of fuzzy logic and discrete models with the purpose to construct the model of control system Dintsis D.Yu. This article deals with the boundaries of applicability the extended antonyms’ logic for development of control information systems. The problems of transition in going from the fuzzy logic model to automatic model, which is represented in view of stochastic automaton or discrete-event model, is also considered.
