Title:
ESTIMATION METHOD FOR ESTIMATING ESTIMATION TARGET INCLUDED IN ANALYSIS CONDITION, ANALYSIS METHOD, PROGRAM, AND ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/034616
Kind Code:
A1
Abstract:
The present invention provides an estimation method that can quickly and accurately estimate an estimation target included in an analysis condition. An estimation method according to the present invention is characterized by including: a measurement step for measuring measurement data at one or more measurement point; a first analysis step for using an analysis condition including an estimation target to perform an analysis and obtain an analysis result; a second analysis step for setting a value obtained by applying perturbation to the value of the estimation target used in the first analysis step as the value of the estimation target so as to perform an analysis and obtain an analysis result; and a calculation step for calculating a sensitivity matrix on the basis of the analysis result of the first analysis step and the analysis result of the second analysis step, calculating an error between the analysis result of the first analysis step and the measurement data at the measurement point or data calculated from the measurement data, and calculating the amount by which the value of the estimation target is to be changed from the sensitivity matrix and the error.
