Planning accelerated life tests with random effects of test chambers

recommendations! Published in 2018 at "Applied Stochastic Models in Business and Industry"

DOI: 10.1002/asmb.2296

Abstract: In accelerated life tests (ALTs), test units are often tested in multiple test chambers along with different stress conditions. The nonhomogeneity of test chambers precludes the complete randomized experiment and may affect the life‐stress relationship… read more here.

DOI: 10.1002/sim.10233

Abstract: We propose a parametric model for describing chronic disease mortality from cohort data and illustrate its use for Type 2 diabetes. The model uses ideas from accelerated life testing in reliability theory and conceptualizes the… read more here.

DOI: 10.1007/s12206-018-0507-z

Abstract: Prognostics methods model the degradation of system performance and predict remaining useful life using degradation data measured during service. However, obtaining degradation data from in-service systems in practice is either difficult or expensive. Therefore, accelerated… read more here.

DOI: 10.1016/j.triboint.2018.12.005

Abstract: Abstract This study proposes a new wear life model, focusing on the adhesive wear phenomena that occur in tripod type CVJs. For the development of the wear life model, kinematic analysis was performed to derive… read more here.

recommendations! Published in 2017 at "Journal of Quality Technology"

DOI: 10.1080/00224065.2017.11917990

Abstract: An accelerated life test (ALT) is often well planned to yield the most statistical information given limited test resources. Nevertheless, ALT planning requires rough estimates of the model parameters as an input, called planning values.… read more here.

DOI: 10.1080/00949655.2024.2405848

Abstract: Accelerated life test provides a feasible and effective way to rapidly derive lifetime information by exposing products to higher-than-normal operating conditions. However, most of the previous research on accelerated life test has focused on the… read more here.

DOI: 10.3390/axioms12050417

Abstract: The analysis of the constant-stress partially accelerated life test was considered under progressive Type-II censoring when the lifetime of the products follows a two-parameter bathtub-shaped distribution. The maximum likelihood estimates of the unknown parameters were… read more here.
