Problem #4
PERT Analysis: Consider the project with thefollowing estimates for activity times and precedence relationships(be sure to use the triple time estimate). All times are indays:
Activity | Optimistic Time | Most Likely Time | Pessimistic Time | Immediate Predecessor(s) |
A | 3 | 4 | 6 | --- |
B | 5 | 7 | 10 | --- |
C | 2 | 3 | 11 | A |
D | 2 | 5 | 8 | B |
E | 1 | 7 | 7 | B |
F | 3 | 5 | 7 | C, D |
G | 7 | 8 | 9 | D, E |
H | 2 | 6 | 10 | F |
What is the expected duration of the project?
If the deadline of the project is 26 days, what is theprobability of finishing the project on time?
