CONSTANT STRESS ACCELERATED LIFE TESTING DESIGNWITH TYPE-II CENSORING SCHEME FOR PARETO DISTRIBUTION USING GEOMETRIC PROCESS
In many of the studies concerning Accelerated life testing (ALT), the log linear function between life and stress which is just a simple re-parameterization of the original parameter of the life distribution is used to obtain the estimates of original parameters but from the statistical point of view, it is preferable to work with the original parameters instead of developing inferences for the...
متن کاملEstimating Costs of Maintenance Service Policy Using Step Stress Partially Accelerated Life Testing for the Extension of Exponential Distribution under Type II Censoring
The maintenance service policy plays a main role to assist any manufacturing organization for safe and available its equipment's and maintenance cost effective. Therefore, we need to estimate the costs of maintenance service policy. The partially step -stress accelerated life test is assumed when the lifetime of test units follows an extension of exponential distribution. Based on Type II censo...
متن کاملOptimal Planning of Failure-Step Stress Partially Accelerated Life Tests under Type II Censoring
Abstract This paper considers optimum plans for failure-step stress partially accelerated life tests with two stress levels under type-II censoring assuming Weibull distribution as a lifetime model. The optimum test plans determine the optimum proportion of test units failing at each stress according to a certain optimality criterion. The D-optimality criterion is considered. Some numerical ill...
متن کاملexponentiated-Weibull distribution under type II censoring
This paper considers the three-parameter exponentiated Weibull family under type II censoring. It first graphically illustrates the shape property of the hazard function. Then, it proposes a simple algorithm for computing the maximum likelihood estimator and derives the Fisher information matrix. The latter one is represented through a single integral in terms of hazard function, hence it solve...
متن کاملStatistical Inference for the Lomax Distribution under Progressively Type-II Censoring with Binomial Removal
This paper considers parameter estimations in Lomax distribution under progressive type-II censoring with random removals, assuming that the number of units removed at each failure time has a binomial distribution. The maximum likelihood estimators (MLEs) are derived using the expectation-maximization (EM) algorithm. The Bayes estimates of the parameters are obtained using both the squared erro...
