Optimisation of K-Out-Of-N systems subject to common-cause failures with repair provision
Abstract This paper considers K-Out-Of-N systems that is subject to two modes of failures, Common cause failures (CCFs) and Random failures, We assure that the system is repaired after each system failure. We develop an optimality criterion leading to the optimal number of units N ∗ for a K-Out-Of-N system, based on cost considerations. Numerical examples are included to illustrate the procedure.
