Abstract
A facility state diagnosis model generator generates a shape data group in which any of a plurality of winding cores is correlated with any of a plurality of pieces of group data, and generates a replacement data group in which correspondence relationships between the winding cores and the group data are replaced with each other in all combinations of the plurality of winding cores and the plurality of pieces of group data, and generates or updates a plurality of learned models indicating that a cause of a defect is any of the plurality of winding cores by using the replacement data group.
