Abstract :
Both reliabilities and costs are used to find the subsystems with the lowest overall expected cost. The authors begin by reviewing some of the concepts of expected value. They then address the problem of choosing among several competing subsystems. These concepts are then applied to k-out-of-n: G subsystems. A basic program (CARRAC) enables the engineer to explore and graph various options. The use of this program is illustrated with several different cost models
