Document Type and Number:
WIPO Patent Application WO/2017/098601
Kind Code:
A1
Abstract:
The present invention is provided with: a temporal frequency analyzing unit (102) that obtains a temporal frequency distribution of strength by analyzing the frequency of collected data collected from a device to be checked; a deterioration degree distribution estimating unit (103) that estimates a temporal frequency distribution of a deterioration degree on the basis of the temporal frequency distribution of strength and of parameters accumulated in advance for the temporal frequency distribution of strength in a case where the device to be checked is operating normally; and a deteriorated-portion determining unit (105) that determines, on the basis of the temporal frequency distribution of a deterioration degree, at least a deteriorated portion of the device to be checked.
