Indicators of reproducibility and suitability for assessing the quality of production services

Abstract

<p>A technique is proposed for estimating the probability of the possible appearance of defective products or the inconsistency of the production service on the basis of indexes of suitability and reproducibility of the production process.</p><p>The index of reproduction is recommended to be calculated on the basis of the standard deviation, which can be established by the average span of the control map and the limits of the tolerance field. At the same time, the production process must necessarily be in a state of statistical controllability. The suitability index cannot be calculated on the basis of the control card characteristics, but it is evaluated solely on the basis of the total of the standard deviation, which is calculated by the Bessel formula and the tolerance limits. The production process does not need to be statistically controllable. Conclusions on the suitability or insufficiency of the products (production services) are based on the value of the indexes of reproduction and suitability, which can take values less than or greater than one. On the basis of these indexes of obtained values, the probability of production appearance or characteristics of the production process, that does not match the established requirements, is established.</p>

Pyramidal method of generalized spatially connected processing and an example of its implementation in image processing

“…The essence of spatially-connected preparation lies in the detection of intensity differences between samples of the sampled image by eight ranks of connectivity, formation of two-level detection signals, transforming of a set of detection signals into a set of spatially connected contour preparations, functions' formation of the latter and formation by *e-mail: timchen@gmail.com summation of separately masked functions of spatially connected contour preparations of positive, negative, and zero generalized spatially connected preparations. The system of functions of generalized spatially connected preparations has the form 18,19,20 :…”

Development of a combined method for calculating coordinates of laser beam spots using a direct parallel-hierarchical transformation

“…; fluctuations in the parameters of laser beams due to atmospheric turbulence. Each of these groups of phenomena of the interaction of laser radiation with the atmosphere can be detected in the fields of both linear and nonlinear optics [10][11][12][13] . When analyzing the sequence of images of long laser paths, which change rapidly, there is a problem in determining the center of the beam.…”
