المستخلص:
The research aims to find a probability distribution for the times of failure through function Entropy transformation using function reliability and cumulative distribution function, and after test data and found it follows the distribution of Burr TypeXII and experiencing volatility, were derived formula probability distribution of the new transfer application Entropy the probability distribution continuous Burr Type - XII and tested a new function and have found it to function probability Were derived SMA have found function probabilistic aggregate in order to adopt to generate data for the purpose of implementation of simulation experiments and research aims to compare estimate parameters probability distribution that has been extracted from the distribution formula using the methods of estimating possible Azam and the way White and estimation method proposed (appreciation mixed) and compare their adoption Metrology statistical mean square error and mean absolute error , has been using simulation for comparison between preference estimators and sizes different samples was conducted practical application to data from the General Company for electrical Industries was selected sample size (67) include electric motors until get failure in this setups.
