METROLOGICAL SUPPORT OF SELECTIVE MULTI-PARAMETRIC CONTROL
(pp. 32-36)

Abstract. The development of methods for selective measurement control of commercially available products, the quality of which is characterized by a number of parameters, is considered. At the same time, it is necessary to establish reasonable requirements for the accuracy of measurement of parameters, as well as the sample size of controlled products. If the controlled parameters are correlated, the problem of optimizing their number arises.Using the Monte Carlo method (simulation modeling), we investigated the effect of measurement uncertainty and the sample size of controlled products on control reliability indicators. The average risks of the customer and the manufacturer are calculated while monitoring samples of products of various volumes. The calculations were made under the assumption that the quality of each product is characterized by 30 uncorrelated parameters. It is shown that in the considered case there is an almost linear dependence of the mentioned risks on the volume of the controlled sample of products.

Keywords: product quality, sampling accuracy, customer and manufacturer risks, measurement uncertainty, sample size.
