Abstract
Recently, several authors have treated multistate systems and given some results. This paper summarizes the several concepts of s-coherency and shows the relationships between them. An interesting theorem for the existence of series and parallel coherent systems is presented. We have proved IFRA and NBU closure theorems under more general situation than has El-Neweihi, et alii and Ross. We discuss our IFR closure theorem.Keywords
