1 Network exercise (P2) Consider the PERT/CPM network shown below. D A 2 3EFBGJ1467HCI5a. Add the dummy activities that will eliminate the problem ofactivities having the same starting and ending nodes.
2 Network exercise (P2)b. Add dummy activities that will satisfy the following immediate predecessor requirements:ImmediateActivity PredecessorH B, CI B, CG D, E
3 Network exercise with time (P4) Construct a PERT/CPM network for a project with the following activities and times:Activity Immediate TimePredecessor (months)ABC AD AE C, BF C, BG D, Ea) Find the critical path for this project network.b) This project must be complete in 1 1/2 years; do you anticipate difficulty in meeting the deadline? Explain.
4 Consider the following network (P6) (times are in weeks) 725A5F3D6H81G1046B3E73a. Identify the critical path.b. How long will it take to complete this project?c. Can activity D be delayed without delaying the entire project? How about activity C? If so, how many weeks?d. What is the schedule for activity E?
5 Network exercise with time (P7) A project involving the installation of a computer system consists of eight activities. The immediate predecessor and activity time in weeks are shown below:Activity Immediate TimePredecessor (weeks)ABC A 2D B,C 5E D 4F E 3G B,C 9H F,G 3a. Draw the PERT/CPM network for this project.b. What are the critical path activities?c. What is the expected project completion time?
