Same story will be used for the next three questions including this one (Q15, Q16, Q17). Network diagram data for a project is given in the following table:
| Actvity | Initial Node | Final Node | Estimated Duration |
| A | 1 | 2 | 3 |
| B | 1 | 3 | 2 |
| C | 3 | 2 | 2 |
| D | 2 | 4 | 3 |
| E | 2 | 5 | 3 |
| F | 3 | 4 | 2 |
| G | 3 | 5 | 1 |
| H | 4 | 6 | 2 |
| I | 5 | 6 | 4 |
Write each path in alphabetical order without space or comma. For example, if a path consists of activities A, B, and C, write the path as ABC, not A,B,C, A B C or CAB.) (you probably need to draw an AOA network on your scratch paper. Keep your work of this question, you may need it for the next two questions following this one.)
Expert Answer
The path and durations are:
| AEI | 10 |
| ADH | 8 |
| BCEI | 11 |
| BCDH | 9 |
| BGI | 7 |
| BFH | 6 |
So, critical path is BCDH
