DRAWING A NETWORK WHEN ACTIVITIES REPRESENTED BY NODES ARE GIVEN
Problem 6.1
Draw the network for the following activities and find critical path and total duration of project.
| Activity | Duration (Days) |
| 1-2 | 20 |
| 1-3 | 25 |
| 2-3 | 10 |
| 2-4 | 12 |
| 3-4 | 5 |
| 4-5 | 10 |
Solution
| Various Paths | Duration of Paths |
| 1 - 2 - 4 - 5 | 20 + 12 + 10 = 42 |
| 1 - 2 - 3 - 4 - 5 | 20 + 10 + 5 + 10 = 45 |
| 1 - 3 - 4 - 5 | 25 + 5 + 10 = 40 |
Hence the critical path is 1 - 2 - 3 - 4 - 5 with project duration of 45 days.
