Finding Critical Path?

Can you please tell me what would be critical path of the following diagram. Is it: a->c->f or a->d->g or both

I drew the network diagram using the following table:

Network Diagram: enter image description here

Solution

  • Assuming the network diagram is correct, a->c->f has a cost of 6 + 6 + 9 = 21. a->d->g has a cost of 6 + 7 + 7 = 20. So a->c->f would be the longest (and hence critical) path.

    Please note that I did not take into account any of the crash durations, costs, etc. from the original table. People should work 40-hour work weeks, not "crash". :)
