Abstract
This paper discusses the preservation of some stochastic orders between
two interdependent series and parallel systems when the survival and distribution
functions of all components switch to the exponentiated model. For the series systems,
the likelihood ratio, hazard rate, usual, aging faster, aging intensity, convex transform,
star, superadditive and dispersive orderings, and for the parallel systems the reversed
hazard, usual, convex transform, star, superadditive and dispersive orderings are
studied. Also, we present a necessary and sucient condition for being finiteness
of the moments of the switched series and switched parallel systems.
