Zayarnyuk P. The effectiveness improving of electronics reliability evaluation considering features of parameters drift and failures statistics.

The thesis is devoted to the development of parametrical reliability (PR) prediction methods of radio electronic apparatus (REA) considering the drift of the defining parameters (DP) and the influence of defects on it. Predicting methods of PR for different characters of DP drift have been developed. There are the quantile zones method for quasi-deterministic DP drift processes; the method based on the theory of emission for quasi-stationary and stationary drift process. The influence of defects on the reliability, namely, on the failure rate has been researched. The analytical model and nomogram for calculating failure rate have been built. The experimental research of capacity of REA reliability prediction methods have been done and it's performance has been confirmed. Algorithm of using and respective program realization for using of the developed methods and techniques in the overall process of REA reliability ensuring have been proposed.
