Problem 2 The project manager of a task force planning the repair of the domed stadium hopes to be able to complete the construction prior to the start of the next college football season. After reviewing construction time estimates, it now appears that a certain amount of crashing will be needed to ensure the project completion before the season opener. The following time and cost estimates are given. Time (in day) Cost Immediate Activity Precessors Normal Crash Normal Crash A None 5 4 $8.000 $9.000 A 10 $5.000 $9.000 A 15 13 $9.000 $10.200 D B 6 5 $3.000 $4,500 7 5 $2.000 $4,400 F C.D 4 3 $4.000 $5,400 E.F 4 3 $5.000 $8.000 1. The critical path and the project completion time (in normal time) are respectively 2. If the project needs to be shortened by four days, show activities to be crashed in the order of reduction. 3. If the project needs to be shortened by four days, what is the total cost (normal cost plus crash cost)? B 8 E B G
