Abstract
In this note we deal with the allocation of independent and identical active redundancies to a k-out-of-n system with the usual stochastic order among its independent components. The optimal policy is proved both to assign more redundancies to the weaker component and to majorize all other policies. This improves the corresponding one in Hu andWang (2009) and serves as a nice supplement to that in Misra, Dhariyal and Gupta (2009) as well.
