ON RELIABILITY ESTIMATION OF FAULT-TOLERANT SYSTEMS WITH RESERVE RECOVERY

Analytical methods are proposed for reliability estimation of the control systems of critical process plants using indices characterizing the ability of the recovered system to maintain its fault-tolerance and indices that reflect the efficiency of structural and organizational measures for supporting fault-tolerance and are invariant to component reliability variations. The indices tinder consideration are coherent do those of fault-tolerance, but enable one to study system reliability on smaller models.
