Modeling Accelerated Life Tests with Dependent Failure Modes

摘要：

In many life tests, it is not uncommon to observe multiple dependent failure modes. Since a full understanding of the underlying mechanism of such dependence can be extremely difficult, adequate physical models are rarely available. Hence, this research investigates the statistical modeling for constant-stress ALT with multiple dependent failure modes. A statistical ALT model is firstly constructed. The stochastic dependence between different failure modes of a testing unit is established by a Gamma frailty model. It is shown that the proposed model incorporates the ALT model with independent failure modes as its limiting case, and thereby, a hypothesis testing for dependence is naturally motivated.
