QUESTION 13 Data for Problems 13-17. The network for a project (a CPM model) is given below. The numbers on the arcs represent the activity times (in days). Copy the network diagram on a piece of paper and perform the FORWARD PASS and the BACKWARD PASS procedures to compute the early times and the late times. Next, nil in the square blanks on the arcs with the slack times of the activities. Then answer questions 13-17. What is the project completion time? O 13 days O 14 days O 15 days O 16 days QUESTION 14 For activity 4-5, the early start and the early finish times are O ES = 5, EF = 10 O ES = 7, EF = 12 O ES = 9, EF = 14 O ES = 10, EF = 15 QUESTION 15 For activity 2-4, the late start and the late finish times are OLS = 3, LF = 5 OLS = 5, LF = 7 OLS = 6, LF = 8 LS = 7, LF = 9 QUESTION 17 What is the slack time for activity 4-67 1 days 2 days o 3 days 4 days QUESTION 16 The critical path is O 1-2-4-5-6 O 1-3-4-5-6 O 1-3-4-6 O 1-2-4-6
