Mechanism equivalence-driven method for degradation stages identification and change points detection
The present disclosure discloses a mechanism equivalence-driven method for degradation stage identification and change point detection, which belongs to the field of product performance degradation modeling and life prediction technology, comprising S1, preprocessing degradation data of a product and dividing degradation phases; S2, calculating a mechanical equivalence factor (MEF) of each degradation phase; S3, constructing hypothesis testing samples and performing normality test on the samples; S4, performing test for equivalence of variances and means; S5, determining failure mechanism change points and identifying degradation stages; the present disclosure provides a mechanism equivalence-driven method for degradation stage identification and change point detection, based on the theory of mechanism equivalence degradation modeling, the Tweedie exponential dispersion process (TEDP) is used to model the product degradation process, aiming to improve the accuracy and reliability of degradation stages identification and change points detection.

Change point detection device and program
The present disclosure is a change point detection device including a clustering unit that clusters prescribed dimensional data at each time point in a preset past period and current period and thereby classifies the data into clusters. This clustering unit calculates centroid coordinates of each cluster at an immediately preceding time point when time-series data was input, on the basis of coordinates of each set of prescribed dimensional data belonging to each cluster, and prestores, in a storage unit, first handover data that associates the centroid coordinates of each cluster with the classification results of the prescribed dimensional data at each time point. At the latest time point when the latest data is observed, the clustering unit clusters and classifies prescribed dimensional data at each time point constituting the time-series data for the past period and current period at the latest time point, on the basis of the difference between the first handover data at the immediately preceding time point read from the storage unit and the time-series data for the past period and current period at the latest time point.

Change point detection device and program
The present disclosure is a change point detection device comprising a clustering unit that classifies data having a predetermined dimension, at each time point in a preset past period and a current period into clusters by clustering the data. The clustering unit calculates centroid coordinates of each cluster on the basis of coordinates of data having each predetermined dimension and belonging to each cluster at an immediately preceding time point, that is an immediately preceding time point at which the time-series data was input, and stores, in a storage unit, first handover data that associates the centroid coordinates of each cluster and the classification result of the data having the predetermined dimension at each time point. The clustering unit clusters, on the basis of the difference between the first handover data at the immediately preceding time point, retrieved from the storage unit at a latest time point at which latest data was observed, and time-series data of the past period and the current period at the latest time point, the data having the predetermined dimension, at each time point constituting the time-series data of the past period and the current period at the latest time point.
