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.

Optimum step‐stress for temperature accelerated life testing
Quality and Reliability Engineering International, 2007AbstractStep‐stress accelerated life testing is a design strategy where the stress is modified several times during the test. In this work we address the problem of designing such a test. We focus on temperature accelerated life testing and we address the problems of setting the step duration and the stress levels.
