Abstract :
This investigation presents a method for determining the optimum mean time between failures (MTBF), mean time to repair (MTTR), and the number of redundant units to use in a multistage system to achieve a given availability at minimum cost. The method (basically a dynamic programming algorithm) is illustrated by a three-stage example.
