We obtain the maximum likelihood estimator and the simulated moment estimator of parameters of two-parameter exponential distribution with full sample size based on tampered failure rate model under step-stress accelerated life testing.

We obtain the maximum likelihood estimator and the simulated moment estimator of parameters of two-parameter expo- nential distribution with censored sample based on tampered failure rate model under step-stress accelerated llfe testing.

Also in the paper,we get the point estimator of unknown parameters by using the maximum likelihood estimator method and simulated moment estimator method based on the censored sample.

The simulated GMM adopted in this paper is forthright and efficient.
