1. A method, comprising:

  • performing a first diagnostic analysis of an industrial asset during a first time period to obtain first data;

    generating, using a model, a health profile for the industrial asset based upon the first data, the health profile describing a predicted condition of the industrial asset during a second time period subsequent to the first time period;

    performing a subsequent diagnostic analysis of the industrial asset during the second time period to obtain second data;

    evaluating the health profile for the industrial asset based upon the second data obtained via the diagnostic analysis of the industrial asset to determine whether there is a discrepancy between an actual condition of the industrial asset during a second time period and the predicted condition;

    responsive to a determination that there is a discrepancy between the actual condition and the predicted condition, obtaining operational record data indicative of operations that have been performed with the industrial asset prior to the prediction period and determining from the operational record data, whether a preemptive operation occurred that prevented the predicted condition from occurring;

    determining, in response to a determination that the preemptive operation did occur, not to update the model to account for the discrepancy or updating, in response to a determination that the preemptive operation did not occur, the model to create an updated model; and

    responsive to predicting that embedding a sensor configured to measure at least one of structural fatigue, vibrations or wall thickness will increase an accuracy of the generating the health profile by more than a threshold corresponding to a level of interference with operational performance of the industrial asset associated with the embedding of the sensor, facilitating an embedding of the sensor within the industrial asset based upon the updated model and generating an updated health profile for the industrial asset using the sensor.
