4.1 Predictive methods for failure diagnosis and prognosis

Since the early 2000s, the competitiveness of high-tech sectors such as space, transport systems, renewable energies, aeronautics, defense, high-risk industries, etc., has required a great deal of innovation to reduce operating and maintenance costs in the event of equipment failure.

To achieve these objectives of improving operating safety, reliability and availability, a great deal of research and study has gone into the development of predictive analysis methods for early detection of the onset of a failure, and prediction of the time to failure (DEFAD), or the probability of operation for a certain period of time (DEFAD is commonly referred to as RUL – remaining useful life). Using powerful statistical...
