| Abstract: |
A method and system of forecasting reliability of an asset is provided. The method includes identifying peer units of the asset by using selected criteria, performing a search for the peer units based upon the selected criteria, and constructing local predictive models using the peer units. The method also includes estimating the future behavior of the asset based upon the local predictive models and dynamically updating the local predictive models to reflect at least one change in the criteria.

1. A method of forecasting remaining useful life of an asset, comprising: identifying peer units of the asset from a set of potential peer units by using selected criteria and performing a search for the peer units based upon the selected criteria; using a first evolutionary algorithm for processing a defined degree of closeness between said peer units and said asset; constructing local predictive models using the peer units; estimating the remaining useful life of the asset based upon the local predictive models; and updating the local predictive models to reflect at least one change in the criteria using a second evolutionary algorithm.
