Expert subjectivism accounting method at quality estimation

Abstract

This paper describes a method allowing to take into account the subjectivism of experts while estimating the quality of technical products. Subjectivism in the quality estimation is perceived as the influence of external environment described by the errors of 1-st and 2-nd kind. We show that subjectivity can not be accurately assessed based on the classical (two-dimensional) measurement logic. More accurate are the calculations based on four-digit logic of measurements, in which besides judgments like «true statement» and «true negation», there are two additional ones: «false allegation» and «false negation».
