1 Network exercise (P2) 1 2 5 3 467 Consider the PERT/CPM network shown below. a. Add the dummy activities that will eliminate the problem of activities having the same starting and ending nodes. A B D E C F G H I J
2 Network exercise (P2) Immediate ActivityPredecessor H B, C I B, C G D, E b. Add dummy activities that will satisfy the following immediate predecessor requirements:
3 Network exercise with time (P4) Activity Immediate Time Predecessor (months) A - 4 B - 6 C A 2 D A 6 E C, B 3 F C, B 3 G D, E 5 Construct a PERT/CPM network for a project with the following activities and times: a) 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) 1 2 3 4 5 6 A5A5 C7C7 B3B3 E7E7 D6D6 F3F3 G 10 H8H8 a. 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) Activity Immediate Time Predecessor (weeks) A -3 B -6 C A2 D B,C5 E D4 F E3 G B,C9 H F,G3 A project involving the installation of a computer system consists of eight activities. The immediate predecessor and activity time in weeks are shown below: a. Draw the PERT/CPM network for this project. b. What are the critical path activities? c. What is the expected project completion time?
