Abstract

Shown necessity accounting function conversion of measuring instrument when assessing the reliability decision making on the conformity of the object to the requirements on the basis of the results of measurements of its parameters. Considered is the influence of the parameters of the measuring instrument conversion function on the character of decisions and its probability. It is shown that the actual shift characteristic and its sensitivity is within these limits may have different values, which may lead not only to change the probability (uncertainty) of the received solutions, but also to change its character. Applying an auxiliary quantity, homogeneous with the measured one, is proposed in the quality control of an object made with the use of measuring channel and decision-making module. The result of processing this quantity is applied for the additive and multiplicative correction of decision limits. This allows to reducing the impact of imperfect processing characteristics of measuring instrument on the decision making on the conformity of the object (shown on the numerical example).
