Estimating parameters and reliability function of general exponential failure model

This paper deals with comparing different estimators of the two parameters of general failure exponential model as well as estimating reliability function, also with application to real data represent time to failure with certain electric products. The estimators obtained by applying different methods like maximum likelihood, moments, and ordinary least square, then the estimator's are obtained through simulation procedures using different sample size n=25, 50,75,100. Also the estimator's of reliability function is done and the programs are written by (Minitab) to find the best estimators and then to solve the equations for applications.
