Failure data management method based on cluster estimation

摘要

The present invention relates to a technique for recording and managing failure data generated in a facility, wherein the failure recording system manages the failure data for the target facility, where each function has a function to observe whether the facility has a fault. Collects the failure indicator data in the situation that occurred, matches and stores it together with the failure history, cause, and type, extracts a plurality of preset feature values from the failure indicator data, calculates clustering for the failure indicator data, Determine the level of clarity of the evaluation criteria for each fault according to the calculated clustering level, determine whether the determined level of clarity falls within a predefined threshold range, and reclassify the corresponding fault phenomenon according to the determination result. Induces.
