As project manager, Amanda Luo, who is leading one of the Atkinson Engineering Company (AEC) projects, wants you to prepare a project network (AON) and answer questions. His assistant determined the activities required to complete the project, the precedence relationship, and activity times are as follows: Predecessor/s ID Time (days) A None 4 B None 3 C B 2 D A, B 3 E C F B G A 3 7 4 H D, G 4 J E, F 5 K None 3 L J 8 M H, J 3 N K 9 OPORS G, K 6 H, N 5 Q O, P 6 P 3 E, F, R 2 Answer following questions: a. Draw a network diagram for the above project. It must include start and finish nodes and mark the critical path on the network. Compute the early, late, and slack activity times, and you must use the given legend of the node. b. How many noncritical activity/ies is/are merge activity/ies? c. Which activity/ies is/are having both properties of burst and merge? d. Which activities are noncritical, state all? e. How many paths are available in the network? f. What is the project completion time in days? g. State critical path/s for the above project. h. Draw the GANTT chart of the project. i. What is the most slack time an activity has available in the network? j. If activity 'G' is completed by a day earlier than the scheduled time, what will be the impact on project completion time and critical path/s? Briefly explain. k. If there is a delay in the completion of activity 'M' by two days, what will be the impact on project completion time and critical path/s? Briefly explain. 1. If there is a delay in the completion of activity 'J' by one day, what will be the impact on project completion time and critical path/s? Briefly explain.
