The Reliability of Redundant Multiple-Line Networks

Abstract

This paper develops a procedure for determining a lower bound to the reliability of multiple-line redundant networks. The procedure is general in that there are no restrictions on the interconnection pattern between the functions of the network, and it allows, within limitations, different parts of the network to take on different orders of redundancy. The approximation to reliability is very good if the reliabilities of the circuits in the network are close to unity.
