Abstract :
In this paper, we obtain some results on preservation properties of the moment-generating-function and Laplace transform orders under the taking of random minima and maxima. Also, the reversed preservation of these stochastic orders is studied. In following, we investigate the closure of some new certain aging classes under the random minima and maxima.
