Answer #1

The Gantt chart for earliest schedule is as follows:

ID Res Dur ES LF SL 0 1 2 3 4 5 6 17 8 A 2 1 0 2 1 2 B 2 N 2 0 2 0 2 с 3 2 2 4 0 3 3 D 1 1 2 5 2 1 E 2 3 N 4 7 0 2 2 F 1 2 4

The Gantt chart according to resource-constraint is as follows:

1. Move A from ES = 0 to ES = 2

2. After completing A schedule activity C from ES = 3

3. Do not move activity D

4. After completing C schedule activity E and From from ES = 5

5. After completing E and F schedule Activity G from ES = 8

Dur ES LF SL 0 1 2 3 4 5 6 7 8 9 LO 11 1 2 3 0 2 2 2 0 2 0 2 2 3 5 0 3 3 1 2 3 0 1 3 5 8 0 2 2 2 2 5 8 1 1 1 1 8 9 0 1 3 4 5

The project completion time of the resource-constraint scheduling is 9 days.
