Abstract
A method for establishing controlled by external influence intervals of control and maintenance of technological line elements on the basis of monitoring their control parameters is proposed. The method uses a complex-valued transformation of a power series, which is reconstructed from a sequence of measured values to obtain the asymptotic value of the sum of the series for the corresponding parameter. A maintenance event is scheduled for the expected time when the predicted parameter value reaches one of the boundaries of its acceptable range. This event is interpreted as a failure of the corresponding element. Algorithms for predicting failure events in the near and far regions are considered, the difference between which is made in relation to the ratio of the characteristic time interval to the available interval of changes in the time series. The results obtained can be used to build an intelligent recovery system for technological lines for various purposes.
