Patent ID: 7505879

Claim:
A method for generating a multivariate analysis model expression for a processing apparatus, the method comprising: a first step in which a recurrent matrix of detection data provided by a plurality of sensors in a processing apparatus operating with first setting data is ascertained through multivariate analysis for each processing apparatus among a plurality of processing apparatuses that operate based upon the first setting data, the plurality of processing apparatuses including a processing apparatus designated as a reference processing apparatus and a first processing apparatus that is not the reference processing apparatus; a second step in which a recurrent matrix of detection data provided by the plurality of sensors in the reference processing apparatus is ascertained through multivariate analysis when the reference processing apparatus operates based upon new second setting data with the second setting data; a third step in which a recurrent matrix of detection data with the second setting data in the first processing apparatus is ascertained based upon the recurrent matrix determined through the first step for the first processing apparatus, the recurrent matrix determined through the first step for the reference processing apparatus and the recurrent matrix determined through the second step for the reference processing apparatus, wherein the third step does not use detection data obtained from the first processing apparatus operating with the second setting data; a fourth step in which a multivariate analysis model expression to be used to evaluate an apparatus state of the first processing apparatus or to predict processing results in the first processing apparatus is generated based upon the recurrent matrix ascertained through the third step; and a fifth step of storing the multivariate analysis model expression in a computer-readable storage medium.
