Failure Inference and Optimization for Step Stress Model Based on Bivariate Wiener Model
S. Shemehsavar, Morteza Amini
In this paper, we consider the situation under a life test, in which the failure time of the test units are not related deterministically to an observable stochastic time varying c…

Optimal design for step-stress accelerated test with random discrete stress elevating times based on gamma degradation process
Morteza Amini, Soudabeh Shemehsavar, Zhengqiang Pan
Recently, a step-stress accelerated degradation test (SSADT) plan, in which the stress level is elevated when the degradation value of a product crosses a pre-specified value, was…
