Beschreibung
Zusammenfassung:	It is disclosed a computer-implemented method for characterizing the evolution with duration of operation of the state of health of a population of devices, the method comprising training a model on a database comprising, for each device among the population of devices, a value of duration of operation of the device and a corresponding state of health of the device, said model being a random process comprising at least the sum of:- a term representing average evolution of the state of health of the population with duration of operation, and- a term representing an inter-device variability of the degradation of the state of health at equal duration of operation, the variance of said term evolving with the duration of operation.
