A Problem in Accelerated Life Testing
Journal of the American Statistical Association, 1971Abstract Parameters of the Power Rule Model are estimated using data from censored sample life tests conducted at accelerated environments. By amending the functional form of the model, it is possible to obtain estimators that are asymptotically independent.

A Bayesian Method for Planning Accelerated Life Testing
IEEE Transactions on Reliability, 2015In this paper, a Bayesian criterion is proposed based on the expected Kullback-Leibler divergence between the posterior and the prior distributions of the parameters of interest. We call the Bayesian criterion the reference optimality criterion, which is to find an optimal plan to maximize the amount of information from the data.

A model for step‐stress accelerated life testing
Naval Research Logistics (NRL), 2003AbstractModern technology is producing high reliability products. Life testing for such products under normal use condition takes a lot of time to obtain a reasonable number of failures. In this situation a step‐stress procedure is preferred for accelerated life testing.

Accelerated Life Testing of Capacitors
IRE Transactions on Reliability and Quality Control, 1957One of the problems facing the designer of modern electronic communication systems is the ultimate reliability to be achieved under service conditions. The required level of reliability together with the unavoidable complexity of present-day equipment calls for components having extremely low failure rates.

Model-Robust Test Plans With Applications in Accelerated Life Testing
Technometrics, 2003We study a criterion based on a weighted asymptotic sample ratio (ASR) that yields model-robust test plans with relatively low ASRs under different models. We apply the criterion to accelerated life test planning in which interest lies in estimating life quantiles and there is uncertainty as to whether the Weibull or the lognormal model best describes ...

On Imprecise Statistical Inference for Accelerated Life Testing
2016Accelerated life testing provides an interesting challenge for quantification of the uncertainties involved, in particular due to the required linking of items’ failure times, or failure time distributions, at different stress levels. This paper provides an initial exploration of the use of statistical methods based on imprecise probabilities for ...

Estimation for a weibull accelerated life testing model
Naval Research Logistics Quarterly, 1984AbstractIt is sometimes reasonable to assume that the lifetime distribution of an item belongs to a certain parametric family, and that actual parameter values depend upon the testing environment of the item. In the two‐parameter Weibull family setting, suppose both the shape and scale parameters are expressible as functions of the testing environment.

Accelerated Life Tests at Higher Usage Rates
IEEE Transactions on Reliability, 2005Accelerated life tests are extensively used to provide quickly the information about the life distributions of products. Test units are subjected to elevated stresses which yield shorter lives. For some products whose life is defined by usage, e.g., mileage and cycles, test units are also run at higher usage rates (UR) to compress the test time.
