Abstract
A method for estimating a Remaining Useful Life of a subject equipment, with a preliminary phase including the following steps: acquire test observations (step) and produce test time series (S) of at least one signature; partition the test time series to obtain severity classes corresponding to the ageing phases of the test equipment devices (step); carry out an initial learning of a diagnosis model on the test equipment devices (step); perform a second learning of a signature prediction model (step). There is also an operational phase including the following steps: acquire observations when in operation on the subject equipment and produce an extrapolated time series using the prediction model; classify the extrapolated time series using the diagnosis model and derive the remaining useful life of the subject equipment.
