Annotation: The paper proposes an approach for evaluating performance reliability of technical equipment by available sample of failure times given when information on actual operating conditions is incomplete. It is suggested to define fuzzy reliability model parameters with piecewise continuous second-order polynomial membership functions. The article provides an example of fuzzy survival function and gamma-percentile life evaluating.

Keywords: reliability, survival function, gamma-percentile life, fuzzy set, fuzzy number, fuzzy probability, polynomial membership functions
