Being evaluation method of the distribution which is decided whether or not evaluation method of distribution and production manner of the product, evaluation system

摘要

PPROBLEM TO BE SOLVED: To provide a method for evaluating the distribution for determining whether or not the distribution of a plurality of observation values collected in a time series manner shifts as time goes on, a method for producing an article using the evaluation method, a distribution evaluation program, and a distribution evaluation system. PSOLUTION: In the method for evaluating the distribution for determining whether or not the distribution of a plurality of observation values collected in a time series manner shifts as time goes on, a plurality of observation values are normalized (Step S1), a plurality of pairs consisting of two observation values temporally and mutually spaced from the plurality of the normalized observation values are selected, a product of the two observation values composing each pair by pair is obtained, and a representative value a of a product of a plurality of the pairs is calculated (Step S2). When the representative value a is larger than a threshold value , it is determined that the distribution of a plurality of the observation values shifts as time goes on (Step S3).
