| 摘 要： | For many products, distributions of their life mostly comply with increasing failure rates in average （IFRA）. Aiming to these distributions, using properties of IFRA classification, this paper gives a non-parametric method for processing zero-failure data. Estimations of reliabilities in any time are first obtained, and based on a regression model of failure rates, estimations of reliability indexes are given. Finally, a practical example is processed with this method.
