Consider the data of Table 2.2 for a fictitious project with 12 non dummy activities
(and a dummy start (1) and end (14) activity). The sets Pi and Si are used to refer
to the direct predecessors and successors of an activity i . Note that precedence
relations will be of the FSmin ij D 0 type, unless indicated otherwise. All models
and principles discussed throughout the chapters can be extended to generalized
precedence relations between project activities, resulting in an increase in complexity
but not in a fundamental difference in scheduling approach. Figure 2.12 displays
the AoN network of Table 2.2, where the number above the node denotes the activity
duration.
