Abstract
The reliability equivalence factors of parallel and series systems with n independent non-identical components are obtained. Three different methods are used to improve such systems: (i) improving the quality of several components by decreasing their failure rates, (ii) adding a hot component to the system, and (iii) adding a cold redundant component to the system. The survival function is used as a performance measure of the system reliability to compare different system designs. The rth moment time to failures will be derived in parallel and series systems in Weibull Distribution. [Yousry H. Abdelkader; A. I. Shawky and M. I. Al-Ohally.
