Problem 5-17 (Static) The following CPM network has estimates of the normal time in weeks listed isted for the activities 16) IK10 A(5) (044) (08) a-1. Determine the critical path OACEG OACFG A-B-D-G A-B-E-G 3-2. Determine the early completion time in weeks for the project a-2. Determine the early completion time in weeks for the project Early completion time weeks For the data shown, reduce the project completion time by three weeks. Assume a linear cost per week shortened. NORMAL NORMAL ACTIVITY TIME COST A 5 $ 7,000 B 12,000 8 5,000 CRASH CRASH TIME COST 3 $13,000 7 18,000 7 7,000 10 MacBook Air For the data shown, reduce the project completion time by three weeks.
