One embodiment provides a system that facilitates development of a degradation model. During operation, the system initializes, for a physical asset in a cluster, a set of maintenance times randomly and based on constraints associated with the physical asset. The system estimates model parameters for the physical asset based on a degradation model, which indicates the set of maintenance times, a value of a measured characteristic for the physical asset at a given inspection time, a number of inspections, and a time for a respective inspection. The system calculates updated values for the set of maintenance times based on the degradation model and the estimated model parameters. In response to determining that an average change in maintenance times over all the physical assets in the cluster is greater than a predetermined threshold, the system re-estimates the model parameters and re-calculates the updated values for the set of maintenance times.
