Manufacturing specification determination method, manufacturing method, and manufacturing specification determination apparatus of a metal material

摘要

Provided are a manufacturing specification determining method, manufacturing method, and manufacturing specification determining apparatus capable of enhancing robustness against disturbance during manufacturing of a metal material. Inverse analysis is performed based on a step of acquiring at least one or more performance data determined after a predetermined process in the production of a metallic material, and a predictive model in which the one or more performance data and manufacturing specifications and material properties are linked, and material properties and searching for relevant manufacturing specifications after the predetermined process such that the estimated value of α asymptotes to the desired value.
