1.
Check the reliability of problem 6.11 by using any analytical technique.

2.
This homework problem refers to the network described in the text. All links are potentially possible, and the matrices define the link costs and reliabilities. Assume the network in question is composed of links 1–2; 2–3; 3–6; 6–5; 5–1; 1–4; and 4–6. Compute the two-terminal reliabilities
R26 and
R23 by using the following methods:

(a)
state-space,

(b)
tie-set,

(c)
cut-set,

(d)
keystone-component,

(e)
edge-transformation.
