DAMAGE EVALUATION METHOD AND MAINTENANCE EVALUATION INDEX POLICY

Title:

DAMAGE EVALUATION METHOD AND MAINTENANCE EVALUATION INDEX POLICY

Document Type and Number:

WIPO Patent Application WO/2013/038995

Kind Code:

A1

Abstract:

The first measurements of parts of a subject of specific physical quantities are matched to a damage evaluation index, and the degree of damage corresponding to the first measurements is calculated. The specific physical quantities at the locations corresponding to the first measurement locations are measured at least once in another time period having a different time used than for the first measurements and are matched to the degree of damage calculated based on the second and later measurements and the temporal changes corresponding to the second and later measurement times. A new damage evaluation index is approximately calculated based on the relationship between the first and the second and later measurements and the degree of damage corresponding to the first and the second and later measurements.
