LIMIT RELIABILITY OF STRUCTURAL REDUNDANCY

Abstract

In many cases, reliability can be improved by using the redundancy of system components. This is an approach that is applied especially in information systems. In this paper we study redundant systems with imperfect switches. We show that there exists a limit as the number of redundant components tends to infinity. This limit is defined for typical exponential time distribution to a failure of digital equipment in information systems. Bound estimates are given for the system elements with distributions belonging to the NBUE (new better than used in expectation) or NWUE (new worse than used in expectation).
