USE OF PARTIAL COMPONENT FAILURE DATA FOR INTEGRATED FAILURE MODE SEPARATION AND FAILURE PREDICTION

摘要

Use of a failure model is disclosed which can be used to probabilistically evaluate possible failure modes in the event of failure of a complex component when no forensic analysis of the failed component is performed. When component failures do occur, contemporaneous sensor and operation data may be used to update and refine the failure model, whether a forensic analysis of the failed component is performed or not. Further, when no component failure is reported, the contemporaneous sensor and operation data may be used to predict component failures.

1. A computer-implemented method for processing failure events, comprising the acts of:
acquiring, at a data collection system, sensed parameter measurements over time from a plurality of devices remote from the data collection system; determining, via execution of a processor-executed routine, whether a failure event for a component of interest within the plurality of devices has been received into an accessible data store, wherein the failure event may or may not include a mode of failure for the respective component; if the failure event has been reported and a mode of failure is indicated, updating a failure model based on the indicated mode of failure and a set of contemporaneous sensed parameters for the respective device; if the failure event has been reported and the mode of failure is not indicated, updating the failure model based on a probabilistic assignment of possible modes of failure and the set of contemporaneous sensed parameters for the respective device; and storing the updated failure model for subsequent use or updates.
