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.
