Abstract

While significant results are available which allow estimation of reliability measure for systems with permanent faults, no generally applicable results are available for intermittent (transient) faults. Methods are presented here which allow reliability evaluation for systems with both intermittent and permanent faults. Two reliability measures, instantaneous and durational reliabilities, are defined and methods to compute them are given. Computed results for the durational reliability for various redundancy schemes are compared.
