Abstract: To perform a prognostic health analysis for an asset, a plurality of independent stochastic simulations are performed using transition probabilities of a discrete Markov Chain model. A prognostic asset health state evolution is computed over a time horizon from the plurality of independent stochastic simulations. An output is generated based on the computed prognostic asset health state evolution.

Abstract: To perform a prognostic health analysis for an asset (11-13), a stochastic simulation is performed to obtain a prognosis for the evolution of the asset health state. The prognosis is updated based on sensor measurements using a particle filter.
