 In this paper, we discuss stochastic comparisons of active redundancy at component level versus system level. We also consider series systems in order to compare their lifetimes using the usual stochastic, the hazard rate and the reversed hazard rate orders, for two cases: (i) the spare and parent components are independent and have the same distribution, and then (ii) the spare and parent components are dependent and have not the same distribution. ./files/site1/files/72/6Abstract.pdf

Keywords: Stochastic orders, Component redundancy, System redundancy, Coherent system.
