The selection procedure of significant factors in modeling process

Abstract

In this article, a set of indicators, which  includes significant input parameters, is determined using a modified method of random balance. The parameters for the model evaluation were defined to complete this task. The resulting mathematical model is tested for adequacy by Pearson’s criterion. This model allows us to convert an array of raw data to a form suitable for the construction of a mathematical model by other more accurate methods to predict the introduction of new types of steel and provides a basis for the development of automated quality control.
