Stress Accelerated Life Testing Situations. Weibull Distribution Statistical Analysis

Basing on the conclusion of others on single stress accelerated life test for Weibull distribution, the paper analyses the data on double stress accelerated life test for Weibull distribution and gives the statistical methods of constant-stress accelerated life test ( including type I censored and type II censored ) and step-stress accelerated life test. Especially, the paper gives a new method of extend estimation of reliability parameters, the method improves the accuracy of extent estimation. Moreover, the paper discusses the statistical analysis for zero-failure data.
