21. Dummy Activity Situations (Figure 4a) F H G E a. Activities F and G have the same predecessor (E) and the same successor (H)

22. Dummy Activity Situations (Figure 4b) E A B C D b. Activity A and B have a common predecessor (E), but they also have different predecessors (C and D)

23. Dummy Activity Situations (Figure 4c) C D I K J c. Activities C and D have a common successor (K), but also have different successors (I and J)

24. Calculating ES, EF, LS, LF, and Completion Time ES (a) = 0 for the starting activity EF (a) = ES (a) + t (a)* ES (a) = max [EF (all predecessors of a)] Project completion time = max [EF(all ending activities)] * t (a) denotes the duration of activity a LF (a) = min [LS (all successors of a)] LS (a) = LF - t (a)* Forward Pass: Backward pass:
