Minimax design of two‐state k‐out‐of‐n systems

Abstract The optimal size of k is specified for two‐state k‐out‐of‐n systems that may be functioning or fail in either state. It is assumed that the steady‐state, success and failure probabilities are not known exactly. The problem is reduced to finding the saddle‐point solution to a minimax optimization problem. An example shows that the minimax design is robust with regard to uncertainty.
