Abstract | Design of optimal Accelerated Degradation Testing (ADT) plan has been extensively researched over several decades. However, experimenters can often face the situation that the optimal plan is not feasible due to limited resources, even after taking into account the design factors in the planning phase. Therefore, designing a test plan that is equivalent to the target plan using an different stress-loading or a testing condition is needed. However, there exists currently little work in the development of equivalent ADT plan. In this paper, we propose an equivalent cost-effective accelerated degradation test (ADT) plan in the context of a nonlinear random-coefficients model. The proposed method is applied to a well-known constant-stress ADT problem in the literature. The definition and formula used in this paper can applied through a wide range of types of equivalent ADT plans.
