ESTIMATION OF RELIABILITY OF COMPLEX SYSTEMS WITH RENEWAL BASED ON ELEMENT TEST RESULTS
Abstract
The problem of confidence estimation of reliability of complex systems with network structure with
repairable elements is considered. Estimation of reliability of a system is based on test results of its individual
elements (subsystems). Existing methods for solving this problem are designed for relatively simple series-parallel
structures consisting of elements with exponential distribution of time to failure. Solution of this problem is
suggested for the more general model of “monotone structures” with independent renewable elements, as well as
significantlymore general case of “aging” system elements (with monotonically increasing function of failure rate).
It is assumed that elements of the system are restored regardless of the state of other elements. In addition, the
solution of this problemis obtained in the natural, fromthe practical point of view, asymptotic behavior for the case
of high reliability (fast recovery) system elements.
