1. [35 Points] [Exercise 5.1] For the project date in Table 5.2, redefine the activity durations in terms of the PERT estimates presented as follows. Activity 1-2 1,2,3 2-3 7,8,9 2,3,4 3-5 9, 10, 11 1-4 7,8,9 2-4 1,2,3 4-5 0, 1,2 If the other activity data are the same as presented in Table 5.2, compute the scaled CAF for each activity in the project and use the CAF criterion to schedule the project. Compare the CAF schedule to the ACTIM schedule.
