This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

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.) Calculate the scheduled completion time and identify the critical path.

(B.) What is the slack time (float) for activities A, D, E, and G?

Construct the network diagram b. Identify each activity's EST, EFT, LST adn LFT c. Identify all paths. Which path is the critical path? d. Calculate the slack each activity? e. How long will it take to complete the project?

Given the information in the following table

Activity Duration Predecessor
a 4 None
b 6 a
c 4 a
d 2 c
e 4 b
f 5 b, d
g 3 c
h 4 f,g
i 2 e, h

a. Construct the network diagram
b. Identify each activity's EST, EFT, LST adn LFT
c. Identify all paths. Which path is the critical path?
d. Calculate the slack each activity?
e. How long will it take to complete the project?
