Identifying Float Times and The Critical Path (General Math - Year 12)

 1. Float Times

 2. Critical Path

EX1:

Solution

Find EST: 

0-Vertex: 0

1-Vertex: 4

2-Vertex: 3

Update 0-Vertex: 12 so finallisation is 12

3-Vertex: 23

4- Vertex: 15

5-Vertex: 32

6-Vertex: 42 and 24, so finallisation is 42.

                            

Find LST

6-Vertex: 42

5-Vertex: 32

4-Vertex: (33,27) chose minimum

3-Vertex: 23

1-Vertex: 12

2-Vertex: (15,13,3)
