Some Stochastic Orderings Among (n-1)-out-of-n Systems from Scale Components

Abstract:   (506 Views)

This paper discusses the hazard rate order of the fail-safe systems arising from two sets of independent multiple-outlier scale distributed components. Under certain conditions on scale parameters in the scale model and the submajorization order between the sample size vectors, the hazard rate ordering between the corresponding fail-safe systems from multiple-outlier scale random variables is established. Under certain conditions on the Archimedean copula and scale parameters, we also discuss the usual stochastic order of these systems with dependent components.

Keywords: Hazard Rate Ordering, Usual Stochastic Ordering, Multiple-Outlier Scale Model, Submajorization Order, (n-1)-out-of-n Systems.
