ScholarBank@NUS Repository. https://doi.org/10.1109/24.488919||Abstract:||A linear cumulative exposure model (LCEM) is used to analyze data from a step-stress accelerated-life-test, in particular, those with failure-free life (FFL). FFL is characterized by a location parameter in the distribution. For the 2-parameter Weibull distribution, the Nelson cumulative exposure model is a special case of LCEM. Under LCEM a general expression is derived for computing the MLE of stress-dependent distribution parameters under multiple censoring. The estimation procedure is simple and is illustrated by a set of experimental data using the 3-parameter Weibull distribution. © 1996 IEEE.||Source Title:||IEEE Transactions on Reliability||URI:||http://scholarbank.nus.edu.sg/handle/10635/63025||ISSN:||00189529||DOI:||10.1109/24.488919|
