FACTOR ANALYSIS DEVICE, FACTOR ANALYSIS METHOD, AND FACTOR ANALYSIS PROGRAM

摘要

A factor analysis device according to one aspect of the present disclosure is provided with a model acquiring unit (108), a monitoring target data acquiring unit (101), a distance calculating unit (108), and a factor analyzing unit (110). The model acquiring unit acquires a normal model. The data acquiring unit acquires monitoring target data for each of a plurality of systems of an appliance. The distance calculating unit calculates the distance between the normal model and a value based on the monitoring target data, for each of the plurality of systems. The factor analyzing unit identifies a system that is an abnormality factor, from among the plurality of systems, on the basis of the calculated distances.
