THE PROBLEM OF THE INFLUENCE OF AUTOMATIC MONITORING ON THE RELIABILITY OF SYSTEMS WITH REDUNDANCY,
Abstract
Systems with active parallel redundancy in which reserve elements (RE) are controlled by check-and switchover (ChS) units is considered. A set of differential equations describes the reliability conditions in terms of failure rates and r sub m (probability that a branch failure is accompanied by elimination or self-elimination of RE). As a result, the probability of successful operation of the entire system is determined. These particular cases are considered: (1) failure rates are constant in time (exponential law of distribution of reliable-operation time); (2) a definite ratio of failure rates of RE and ChS; (3) reliability characteristics of RE and ChS do not change when the number of branches changes; starting from a certain value of the redundancy rate, the probability of successful operation decreases. When the probability of RE self-elimination is sufficiently high, ChS devices are superfluous.
