Assume that the edge reliabilities for the network given in problem 6.3 are R(AB) = 0.95; R(AC)= 0.92; R(AD) = 0.90; R(BC)= 0.90; R(BD)= 0.80; and R(CD) = 0.80.

(a) Repeat problem 6.3(c) for the preceding edge reliabilities.

 (b) Repeat problem 6.3(d) for the preceding edge reliabilities.

(c) Repeat problem 6.3(e) for the preceding edge reliabilities.

(d) Repeat problem 6.3(f) for the preceding edge reliabilities.

(e) If the edge costs are C(AB) = C(AC) c =10; C(AD) = C(BC) = 8; and C(BD) =C(CD) =7, which of the networks is most cost-effective?
