Fuzzy reliability analysis with only censored data
In some cases, failure times cannot be observed, having only censored data. Estimation methods are not applicable and a high degree of uncertainty is present. Fuzzy probability theory to involve the uncertainty and process knowledge is proposed. Fuzzy reliability and fuzzy time for inspection including uncertainty are obtained. RBI method is used to establish inspection frequency, based on a fuzzy target risk.
