关 键 词：Fuzzy logic Reliability Analysis RAID 5 Markov Model 

摘      要：Reliability models for various disk array architectures are *** model is very useful calculating with state space by using transition probability and initial *** practice,sometimes we can not have the exact values of λ,μ,ρbut with some uncertainty about these *** combination fuzzy logic and Markov model method is introduce and analyzed besides the traditionally used reliability measures such as disk array system *** reliability method is a technique for analyzing fault tolerant designs under considerable uncertainty,such as is seen in compilations of component failure rates,the presented model provides the estimation of the lower and upper boundary of RAID 5 with a single run of the model.
