Question 3. Critical Chain Scheduling
Consider the following network diagram information
Task | Predecessor | Duration (weeks) |
A |
| 3 |
B | A | 5 (4) |
C | A | 4 (3) |
D | B | 1 |
E | C, D | 2 |
(a) Draw any network diagram which shows the precedence relationship and Identify the critical path and the length of it.
(b) Suppose that the task B and task C are performed by the same resource (only one unit), and it has been decided that the task B is going to be conducted earlier than the task C – this creates a new precedence relationship between B and C due to the resource. The new duration by the single unit is 4 and 3 for B and C, respectively. Now identify the critical path again here – This new critical path may be called a critical chain if we assume that this reduced task duration is very aggressive compared to previous task durations.
(c) Consider the new critical path obtained in part (b) as a critical chain. Then, draw a network diagram to show the critical chain with project buffer(s) and feeding buffer(s) – you do not need to describe the duration of buffers.
