Drawing a complete network
Whichever type of network is drawn, there are three steps:
 |
carry out a forward pass to calculate earliest times; |
|
carry out a backward pass to calculate latest times; |
|
identify critical paths - there may be more than one. |
For an AON network the total float is easily calculated as the difference between the earliest and latest start (or finish) times. As critical activities have a total float of zero, critical paths can then be identified.
