Reliability based corrective maintenance activity timing

Corrective maintenance in the form of scheduled repairs has been increasingly used because of system reliability increase and a good maintenance technique. Mathematical presentation of a reliability indicator is related to the theory of probability and mathematical statistics. When reliability indicators are determined in practice, it is important that the causes of failure of any element in the series of components, based on which the conclusion on element reliability are made, are always the same. Such a series of components is statistically homogenous. Statistically homogeneous series may be realized in practice.
