چكيده لاتين :
In this paper, we consider a coherent system of n components and n active spares.
Then, we investigate stochastic comparisons of the lifetimes of series-parallel systems
and discuss that component redundancy offer greater reliability than the system redundancy
with respect to the hazard rate order and the reversed hazard rate order
for two scenarios, matching spares and non-matching spares
