Abstract:
In this paper، series and parallel systems، when the lifetimes of their components following the scale model are studied and different stochastic orderings between them are discussed. Moreover، we apply these results to the series and parallel systems consisting of exponentiated Weibull or generalized gamma components. The presented results in this paper complete and extend some known results in the literature.
