ASYMPTOTIC METHOD OF EVALUATING RELIABILITY AND MAINTAINABILITY OF HIGHLY RELIABLE NETWORKS AND ITS APPLICATION

An asymptotic exponential failure law for an arbitrary redundant repairable system was generally established in a previous paper by the author, involving the decrease of unit unavailabilities to 0, without assuming exponential life/repair distributions of the units. In the present paper, a new approach is pursued under the same stochastic model, and an exponential approximation formula for the system reliability is obtained as a first approximate solution to a certain functional equation. Its error bound is evaluated from a second approximate solution to the functional equation. Asymptotic formulae for maintainability and availability of the system are also developed. The usefulness of the method is exemplified by a few examples.
