Statistical design of experiments has been used abundantly in reliability theory in order to improve the quality of a system. Experimentation is a powerful tool locating the optimum levels of the parameters in the production process.
In this paper we have used response surface designs (optimum rotatable designs) incorporating independent experimental errors for improving the performance of a system by increasing the reliability for a given mission time or increasing the mean life. Rotatable designs with independent and homoscedastic errors are used in estimating regression parameters by Least Squares method assuming life distribution to follow Weibull distribution and experimental errors follow independent Normal distribution.
