Open publisher page 1 citations

Abstract

The tampered failure rate model is applied to the discrete life distribution occasion under the step-stress accelerated life testing for the first time.In this article,the maximum likelihood estimations of the parameters for geometric distribution with full sample size based on tampered failure rate model under step-stress accelerated life testing are derived.The feasibility of this method is illustrated by using one example.
