Parameter Estimation of a Multistate Model for an Aging Piece of Equipment under Condition-Based Maintenance

We study a multistate model for an aging piece of equipment under condition-based maintenance and apply an expectation maximization algorithm to obtain maximum likelihood estimates of the model parameters. Because of the monitoring discontinuity, we cannot observe any state's duration. The obse...
