Abstract�� Under the condition that a key component will have a higher priority of repair, a repairable consecutive-k-out-of-n:G�� system with one repairman was studied. The probability of states was derived by using Markov process. The membership functions of the states to success and failure were defined and the reliability indices of repairable systems were analyzed utilizing reliability theory incorporating fuzzy states. The difference between fuzzy reliability and conventional reliability was compared. When the system was in the working state, the reliability of the system was intuitively characterized by the number of working components. The fuzzy reliability can fully describe the action of system. In the end, an example was given to illustrate the method.
