Title:
Calculation error estimation device and calculation error estimation method
Document Type and Number:
Japanese Patent JP6305298
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable estimation of a calculation error even in a case in which a measurement value of an experiment includes a significant uncertainty.SOLUTION: The calculation error estimation device is provided with: a relative difference computing unit 112; an experimental system sensitivity coefficient vector computing unit 113 that computes an experimental system sensitivity coefficient vector S; a target system sensitivity coefficient vector computing unit 114 that calculates a target system sensitivity coefficient vector S; an input parameter covariance error matrix storage unit that stores an input parameter covariance error matrix W; a post-correction matrix equation derivation unit 115 that calculates an element rof an experimental system uncertainty matrix from the experimental system sensitivity coefficient vectors Sand Sand the input parameter covariance error matrix W, and calculates a target system uncertainty element rfrom the target system sensitivity coefficient vector Sand the experimental system sensitivity coefficient vector S, and the input parameter covariance error matrix W, and then corrects the element ror the element rwith a measurement error ue; a vector adjustment computing unit 116; and a target system physical amount uncertainty computing unit 118.SELECTED DRAWING: Figure 2
