Homework Answers
We know that
E.F = Te + tij
Te = Earliest occurence time = 0 (for A)
tij = duration = 5 (for A)
E.F of A = 5
E.F of B = 5 + 6 = 11
E.F of D = 5 + 8 = 13
E.F of C = 13 + 1 = 14 (max)
Also
L.F = Tl - tij
Tl for C = 14
L.F of C = 14
L.F of D = 14 -1 = 13
L.F of B = 14 - 1 = 13
L.F of A = 13 - 8 = 5 (min)
Also we have
E.S = E.F - tij
L.S = L.F - tij
Total float = L.S - E.S
= L.F - E.F
