Résumé

This paper illustrates the main features of the MUlti-STAte DEgradation Process analysis Tool (MUSTADEPT), a new software tool which allows quantitatively describing the evolution of the degradation process of an industrial equipment, modeled as a discrete-state transport process. Two different, complementary approaches are offered. One is based on statistics, specifically the Maximum Likelihood Estimation (MLE) technique to estimate the parameters of the degradation process model and the Fisher Information Matrix for evaluating the uncertainty associated to the estimates. The other approach relies on information elicited from experts and describes and propagates the associated uncertainty within the DSTE framework. In both cases, the probabilities that the component occupies the different degradation states over time are estimated with the associated uncertaintie
