Problem 3B
Kimmy Gibbler, president Gibbler Industries, has developed thetasks, durations, and predecessor relationships in the followingtable for building new stores. Draw the AON network and answer thequestions that follow.
ACTIVITY | IMMEDIATE PREDECESSOR(S) | TIME ESTIMATES (IN WEEKS) |
OPTIMISTIC | MOST LIKELY | PESSIMISTIC |
A | --- | 5 | 9 | 12 |
B | A | 4 | 9 | 20 |
C | A | 9 | 15 | 14 |
D | A | 5 | 9 | 8 |
E | B | 5 | 6 | 8 |
F | E, C | 3 | 6 | 5 |
G | E, C | 6 | 7 | 20 |
H | F | 5 | 6 | 10 |
I | F | 3 | 4 | 5 |
J | D, G, H | 5 | 4 | 13 |
K | I, J | 5 | 3 | 10 |
What is the expected (estimated) time for activity H?
What is the variance for activity H?
Based on the calculation of estimated times, what is thecritical path?
What is the estimated time of the critical path?
What is the activity variance along the critical path?
What is the probability of completion of the project before week34?
