چكيده فارسي :
Today, many products are designed to function for a long period of time before they fail.
For such highly-reliable products, collecting step-stress accelerated degradation test (SSADT)
data can provide useful reliability information. SSADT is more useful for developing products
when there is inadequate knowledge for test conditions. Some efficient SSADT plans have
been proposed when the underlying failure modes are independent. However, how to design
an efficient SSADT plan for the dependent failure modes with linear degradation data is still
a problem to be solved. The aim of this paper is to provide an SSADT plan for these cases.
Copulas are used to describe the dependence between failure modes. Finally, we use the
proposed method to deal with the SSADT design with dependent failure modes for a real data
set and a simulation study.
