METHOD FOR BUILDING ABNORMALITY DIAGNOSIS MODEL, ABNORMALITY DIAGNOSIS METHOD, DEVICE FOR BUILDING ABNORMALITY DIAGNOSIS MODEL, AND ABNORMALITY DIAGNOSIS DEVICE

A construction method of an abnormality diagnosis model is a construction method of an abnormality diagnosis model of a process for sequentially treating a metal material in a plurality of facilities, and includes: a first model creation step of creating a first abnormality diagnosis model that learns a relationship between measured values at a same time and an abnormality by using the measured values measured at the same time in a predetermined measurement cycle determined in advance for the plurality of facilities; and a second model creation step of creating a second abnormality diagnosis model that learns a relationship between measured values at a same position and an abnormality by using the measured values at the same position of the metal material obtained by compiling the measured values measured in the plurality of facilities for each position of the metal material.
