Construct a network diagram, identify the critical path
The following data were obtained from a project to build a pressure vessel:
Activity Duration Predecessors
A 4 weeks ---
B 4 weeks ---
C 3 weeks B
D 2 weeks A, C
E 3 weeks B
F 5 weeks D, E, G
G 2 weeks B
H 6 weeks F
I 3 weeks G
J 1 week I
Construct a network for the project. Then review and answer (A) and (B).
(A.) Evaluate the scheduled completion time and identify the critical path.
(B.) What is the slack time (float) for activities A, D, E, and G?
