6.3 Consider a 2-out-of-3 system of identical components with constant failure rate A. The system is exposed to common cause failures that may be modeled by a B-factor model. In Fig. 6.8 it is shown that the MTTF of the system has a minimum for B 0. Determine the value of for which MTTF attains its maximum. Explain why MTTF as a function of has this particular shape. 6.3 Consider a 2-out-of-3 system of identical components with constant failure rate A.
