Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The multicriteria substance quality control validity YU.M. VESHKURTSEV, N.D. VESHKURTSEV, D.A. TITOV There is applied a statistical decision-making theory with determining the performance probability of a finite number of hypotheses. We study the validity of multi-criteria substance quality control with a statistical method which includes measuring of probabilistic estimates and their values are determined with values k of the substance composition fitting criteria to the standard. There are considered dependent and independent fitting criteria and the decision payoff about the substance composition fitting according to the standard. There are obtained expressions for calculating the multi-criteria substance quality control validity using dependent and independent criteria of the substance composition fitting to the standard, these expressions are based on the studies. There are presented recommendations on the choice of fitting criteria for a given value of the control validity. The paper also presents a comparison of the calculated values of the multi-criteria substance quality control validity with independent fitting criteria and validity of the control with dependent fitting criteria. Keywords: non-destructive multi-criteria control, substance, fitting criteria, validity of the k-th order, the hypothesis, the decision payoff. Contacts: E-mail: vym1940@mail.ru Pp. 42-48.
