Quality problems and energy fluctuations that may occur in the electrical network, manufacturing errors in the equipment used can also be evaluated within this scope. Failure of the top management to give importance to maintenance work, not providing the training needed by the personnel, the cost of the resourc- es spent for maintenance in some sectors is higher than the cost spent for the breakdown, and there- fore the stopping of the maintenance activities are among the reasons that cause malfunctions. 5.
