In this paper the use of the concept of gamma-cut (interval of confidence) and time dependent fuzzy set theory is proposed in a general procedure to construct the membership function of the fuzzy reliability, when the failure rate is fuzzy. The failure rate of the system is represented by a triangular fuzzy number. A simple numerical example is also presented.
