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: 10.1007/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: 10.1080/00224065.2017.11917990
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.
