In this paper, we investigate the performance of the AFT models when Progressive Type-II censoring schemes are performed. We demonstrate the usefulness of using these schemes. We discuss their testing procedure power, $Bias$, and $MSE$ of the hazard ratio estimates compared to the same sample size of the uncensored data. Theoretically, we derive the models, the $MLE$ scores, and the Fisher information matrix. A comparison between these estimators is provided by using extensive simulation. A real-life data example is provided to illustrate our proposed estimators. ER -
