Estimating Costs of Maintenance Service Policy Using Step Stress Partially Accelerated Life Testing for the Extension of Exponential Distribution under Type II Censoring
نویسنده
چکیده
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 censoring, the maximum likelihood estimates (MLEs) of the model parameters are obtained. Furthermore, the confidence intervals (CIs) of the estimators are constructed. Finally, simulation study are carried out to investigate the accuracy of the MLEs for the parameters involved and illustrate the theoretical results.

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...

This paper considers the simple step-stress model from the Marshall-Olkin generalized exponential distribution when there is time constraint on the duration of the experiment. The maximum likelihood equations for estimating the parameters assuming a cumulative exposure model with lifetimes as the distributed Marshall Olkin generalized exponential are derived. The likelihood equations do not lea...

Censored samples are discussed in experiments of life-testing; i.e. whenever the experimenter does not observe the failure times of all units placed on a life test. In recent years, inference based on censored sampling is considered, so that about the parameters of various distributions such as normal, exponential, gamma, Rayleigh, Weibull, log normal, inverse Gaussian, ...
متن کاملDesign and Analysis of Step Stress Accelerated Life Tests for Censored Data}
Life testing often is consuming a very long time for testing. Therefore, the engineers and statisticians are looking for some approaches to reduce the running time. There is a recommended method for reducing the time of failure, such that the stress level of the test units will increase, and then they will fail earlier than normal operating conditions. These approaches are called accelerated li...
