Experimental Designs for Accelerated Degradation Tests Based on Linear Mixed Effects Models

  title={Experimental Designs for Accelerated Degradation Tests Based on Linear Mixed Effects Models},
  author={Helmi Shat and Rainer Schwabe},
Accelerated degradation tests are used to provide accurate estimation of lifetime properties of highly reliable products within a relatively short testing time. There data from particular tests at high levels of stress (e. g. temperature, voltage, or vibration) are extrapolated, through a physically meaningful model, to obtain estimates of lifetime quantiles under normal use conditions. In this work, we consider repeated measures accelerated degradation tests with multiple stress variables… Expand

Optimal design of constant-stress accelerated degradation tests using the M-optimality criterion
Results show that, with a slightly relaxed requirement of evaluation precision and prediction accuracy, the proposed optimum plan reduces the dispersion of the estimated acceleration factor between the usage stress level and a higher accelerated stress level, which makes an important contribution to reliability demonstration and assessment tests.
