We study reliability equivalence factors of a system of independent and identical components with exponentiated Weibull lifetimes. The system has $n$ subsystems connected in parallel and subsystem $i$ has $m_{i}$ components connected in series, $i=1,\ldots,n$. We consider improving the reliability of the system by (a) a reduction method and (b) several duplication methods: (i) hot duplication; (ii...
