SUMMARY
The method of treatment of results of tests of radio electronic facilities of antiaircraft weaponthat are exploiting by the technical state on index of faultlessness “failsafe switching probability” is worked out in the article. The worked out method plugs in itself: mathematical model of process of tests as a process of wandering of point on a integral grate “amount of the cyclic including – amount of refuses”; mathematical correlations for determination of risks of consumer, mean time of tests of and other with taking into account a priori information (operating supervisions) and results of operating tests on faultlessness on an index “probability of faultless switching on”. The got correlations summarize the known models of proof-testing on faultlessness on the index of type “probability” and, unlike the known models of the truncated successive tests, based on the use of the Bayes methods of account of priory information.
