METHOD AND DEVICE FOR SIMILAR EQUIPMENT CLUSTERING USING FEATURE EXTRACTION METHOD BASED ON SURVIVAL FUNCTION

摘要

Disclosed is a method of clustering similar facilities using a survival rate-based feature extraction method. The similar facility clustering method is performed in a similar facility clustering apparatus including a data processing module, a feature extraction module, and a clustering module, and the data processing module collects maintenance performance data including facility maintenance history information in the process facility Wherein the feature extracting module estimates a fault occurrence interval distribution in a process facility, an optimum distribution determining step of determining an optimal distribution by the feature extracting module, A survival function estimation step of estimating a survival function from an optimal distribution of a failure occurrence interval of each facility determined in the optimal distribution determination step, a feature extraction step of extracting features from the survival function estimated in the survival function estimation step, And wherein the clustering module And a similar facility clustering step of clustering similar facilities based on the extracted features.
