Abstract EN
A parameter estimation problem for a backup system in a condition-based maintenance is considered.
We model a backup system by a hidden, three-state continuous time Markov process.
Data are obtained through condition monitoring at discrete time points.
Maximum likelihood estimates of the model parameters are obtained using the EM algorithm.
We establish conditions under which there is no more than one limitation in the parameter space for any sequence derived by the EM algorithm.
