The two-stage procedure for predicting the remaining useful life of the machines is demonstrated on a case of industrial shot blasting machine. In the first step the generalised Jensen-Reny divergence is calculated from filtered vibration signals. This index serves as a measure for the “distance” between the reference and current samples. In the same time the index is related to the size of progressing fault. In the second step the model of the index trend is calculated and the distribution of the first passage time (the time the index hit the critical value) is evaluated.

On a case of an industrial machine the anticipation of the remaining useful life is performed by employing a Kalman filter for the state estimation of the degradation model.
