Patent ID: 7457674

Claim:
An electronically-implemented model association method for updating estimation models used for system monitoring, the method comprising: for each of a plurality of monitored systems, determining an association between a particular monitored system and at least one of a plurality of estimation models, wherein each estimation model is based upon one of a plurality of distinct sets of estimation properties, each set of estimation properties including at least one among a sensor list, sensor thresholds, training period, and estimation model algorithm, and wherein each set uniquely corresponds to a particular estimation model; updating at least one of the estimation properties; propagating the at least one updated estimation property to each estimation model that corresponds to a distinct set containing the at least one estimation property that is updated; modifying each estimation model that corresponds to a distinct set containing the at least one estimation property that is updated; updating an association between one or more estimation models and at least one of the plurality of monitored systems in response to a structure of at least one monitored system changing; and retaining a system-specific version of each estimation model that is modified.
