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.
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.
