A small sample:
Let ti, to, tm, tn, tt, to be start
times of the associated tasks.
Now use the graph to write the
dependency constraints:

• Tasks o, m, and n can't start until task / is finished, and task /
takes 3 days to finish. So the constraints are:
ti +3≤ to, t₁ + 3 ≤ tm, ti +3 ≤ tn
. Task t can't start until tasks m and n are finished. Therefore:
tm +1≤tt, tn + 2 ≤ tt,
• Task s can't start until tasks o and t are finished. Therefore:
to +3≤ts, tt + 3 ≤ ts
