METHODOLOGY OF JUSTIFICATION THE TYPE AND EVALUATION OF QUALITY GROUP SEARCH OF DEFECTS IN THE REPAIR RADIO-ELECTRONIC MEANS

Abstract

Context. Radioelectronic devices are continuously complicated, which complicates the process of restoring their efficiency,\xa0when the diagnosis consumes the largest labor costs and time. Therefore, the promising direction of increasing the efficiency of the\xa0renewal of modern electronic means is to improve diagnostic support. Objective. The purpose of the article is to increase the efficiency of diagnostic provision of radio electronic means at the expense\xa0of a reasonable choice of the type of group search of defects. Method. In the work analytical studies of conditional algorithms of diagnosis with the use of graph theory theory, probability\xa0theory and the theory of discrete search – a scientific discipline that studies the diagnostic process when restoring the efficiency of\xa0complex technical objects with varying degrees of damage through research and optimization of procedures and algorithms for\xa0detection of a priori – in unknown number of elements with given properties on the finite structurally-bounded set according to some\xa0criterion. Results. The method of choosing the type of algorithm of group search of defects at given restrictions and assumptions on the\xa0criterion of minimum labor costs on the basis of generalization of the graph-analytical model of group search of defects with\xa0quantitative estimation of probabilistic, time and cost indicators of the quality of the process of diagnosing radioelectronic devices\xa0with different degree of damage, which allows to pre-substantiate the most appropriate algorithm for group defects search for use in\xa0the development of diagnostic support for modern radio ectronic means. Conclusions. For the first time, various types of group search of defects with a quantitative estimation of the efficiency of their\xa0use depending on the features of radio-electronic means and the conditions for their restoration of efficiency are considered in a\xa0complex way.
