Increase Of Accuracy Of Parameter Controls Of Granular Materials

摘要

The reliability of parameter controls of granular materials is a prime factor for quality assurance while their production and exploitation. Control reliability of granular materials is hardly influenced by estimation accuracy of a measure of proximity between controlled and standard parameters. If we take into account that the measurement of both inspected, and standard parameters occurs with an error, then while estimation the measure of proximity between them the error will increase. Therefore, the minimization of estimation errors of the proximity measure between controlled and standard parameters of granular materials is a very actual topic. For minimization of this estimation error of the proximity measure between controlled and standard parameters of granular materials on the basis of Euclidean distance we offer a procedure of increasing of correlation between measuring errors of these parameters inclusive of singularities of composition of their image distribution laws. The implementation of this procedure is achieved by ranking of the measured values by ascending order, by experimental estimation of a value □~* with a further calculation of an actual value of a measure of proximity between controlled and standard parameters of granular materials.
