Reliability Assessment for a System with Loaded Reservation and Recovery Based on the Results of Testing Its Elements

The problem of estimation of confidence based on the testing results of elements of one of the main reliability parameters, the availability coefficient for a system with a loaded reservation and recovery of elements in various subsystems, is considered. Approximate confidence boundaries of this parameter are constructed for the case of a high reliability (“fast recovery”) of elements under the assumption that the average recovery time inherent in the elements of the system is small compared to the average time of failure-free operation. Estimates of the accuracy for the confidence boundaries constructed are also obtained.
