Reliability estimation of semi-Markov systems: a case study

In this article, we are concerned with the estimation of the reliability and the availability of a turbo-generator rotor using a set of data observed in a real engineering situation provided by Electricité De France (EDF). The rotor is modeled by a semi-Markov process, which is used to estimate the rotorʹs reliability and availability. To do this, we present a method for estimating the semi-Markov kernel from a censored data.
