Rob Smith is managing a small project at Boston University. He is under pressure to shorten the overall duration of the project by 4 weeks and he wants to do so at the lowest cost possible. In order to meet this objective a number of activities must be crashed.
| Activity | Normal Time (weeks) | Crashed Time (weeks) | Normal Cost | Crashed Cost | Predecessor(s) |
|---|---|---|---|---|---|
| A | 5 | 3 | $800 | $1,600 | - |
| B | 6 | 5 | $350 | $500 | - |

| E | 5 | 3 | $1,350 | $2,250 | C |
| F | 6 | 3 | $600 | $1,500 | B |
What is the duration of the project (in weeks)?
What is the target duration of the project (after crashing the project)?
By how many weeks should activity A be crashed?
By how many weeks should activity B be crashed?
By how many weeks should activity C be crashed?
By how many weeks should activity D be crashed?
By how many weeks should activity E be crashed?
