Prediction of the class of reliability of electronic equipment by the method of converting informative parameters into a discrete code

Abstract: A modification of the method of individual prediction of the reliability class of electronic products for a given operating time (K1 is the class of reliable, K2 is the class of potentially unreliable items) based on the control of informative parameters of products is proposed. The peculiarity of the modification is the transformation of informative parameters into a ternary code. This makes it possible to obtain a model for predicting the reliability class of single-type instances in the form of a logical table, as in the case of the basic method of the threshold logic based on converting informative parameters into a binary code. Unlike the basic threshold logic method, the new model provides higher reliability of forecasting results.
