On a statistical control of a technological process described by a two-dimensional normal distribution

Abstract

In the papera methodology for controlling a technological process described by a two-dimensional normal distribution using new control charts is given, where the control value is Kolmogorov's statistics ρx and ρy and a correlation coefficient (rxy). Using these control charts shows the control of the machine producing the shotgun shells (weapons or other shotgun shells). Control charts are based on Kolmogorov’s consentcriterion and Fisher’s criterion of linear dependence of the components of a random normal vector.
