Dynamic signature to Lifetime comparison of coherent systems

In reliability engineering, comparison of a number of systems of same or different orders and selection of the best design from them are very important issue. Therefore, in this study, the lifetimes of two coherent systems are compared by using their signature vectors and dynamic signature vectors. At the end; some examples are presented. In this paper, comparison of the lifetimes of two coherent systems are implemented in three status by using the dynamic signature vector. By solving of examples, showed that the lifetime of the first system is more than the second system.
