Three-valued system diagnosis and parallel recovery

A generalized three-valued diagnostic model is proposed. A description is given of t1/t1/2-diagnosability with a parallel recovery strategy. The results show clearly that t-1/t-1/2-diagnosis with parallel recovery can effectively shorten the period of recovery time from faults and improves availability of a class of fault-tolerant computer systems, as compared with t-fault diagnosis under the same structural constraint.<
