Type Presentation
Keywords Asymptotic variance, Exponential distribution, Periodic inspection, Tampered failure rate model, Three step stress test.
Abstract In this paper, we discuss the optimal step stress accelerated life test plan under periodic inspection and Type I censoring. The exponential distribution with a failure rate function that a log-quadratic function of stress and the tampered failure rate model are considered. The asymptotic variance of the maximum likelihood estimators of parameters is derived as an optimality criterion and the optimal stress change times are determined. A numerical example will be given to illustrate the proposed inferential procedures.
