Industrial Automatic Control Systems and Controllers Annotation << Back Fuzzy models for decision-making about turbo-unit uptime prolongation, shutting down for maintenance, or introducing operation constraints Krokhin G.D., Mukhin V.S. The paper proposes the new maintenance philosophy for power units of heat power plants based on intelligent diagnostics and fuzzy state models with the objective to increase plant uptime. The variants of solving the multiobjective problem and the ways to determine admissible deviations from unit’s ideal condition are discussed. A fuzzy mathematical programming task is formulated. The paper shows that any such task is a multicriterion optimization problem, where the alternatives, objectives, and constraints can be represented as an optimizing subset.
