Решающее правило при оценке соответствия с учетом неопределенности измерения

Abstract

A procedure for assessing the conformity with specified requirements described in terms of a tolerance interval for a quantity is considered in view of uncertainty of measurement of the quantity. It is shown that if the measurement result is considered as a Bayesian inference then the classical methods of the decision theory, including Bayesian ones should be properly modified. This is compared to the approach of ISO/IEC DGuide 98-4 (2012) which is being developed in order to promote the “Guide to the expression of uncertainty in measurement” (GUM) to the specific tasks of conformity assessment. It is demonstrated that that approach is actually in poor agreement with GUM.
