Tutorial 04 Questions 1. Construct a network activity diagram based on the following information: Activity Preceding Activities A E B A C A D A E B F C.D G E.F H F I G.H J I 2. You have a partial network for your project, and you are about to conduct a forward pass through it. Explain why the early start (ES) for activity G is 23 days, not 19 days. Remember, activity G is a merge activity. 16 E 23 7 G 4 14 F 19 5Referring to the figure above in question 2, suppose that Activity G was the last activity in the network and you were about the start a backward pass. a. What is the project's duration? (Hint: complete the forward pass) b. What are the late finish (LF) and late start (LS) values for Activities E, F, and G? c. Which activity has slack time? How many days? Referring to the figure shown below, suppose that Activity O was the last activity in the network and you were about to start a backward pass. a. What is the project's duration? (Hint: complete the forward pass) b. What are the late finish (LF) and late start (LS) values for activities L, M, N, and O? c. Which activities have slack time? How many days? and you were about to start a backward pass. a. What is the project's duration? (Hint: complete the forward pass) b. What are the late finish (LF) and late start (LS) values for activities L, M, N, and O? c. Which activities have slack time? How many days?

Conduct both a forward and backward pass using AON notation. What is the estimated total duration for the project? b. Identify all paths through the network. Which is the critical path? c. Which activities have slack time? d. Identify all burst activities and merge activities. 6. Explain the concept of a \"dummy variable.\" Why is this concept employed in AOA notation? Why is there no need to use dummy variables in an AON network? 7. Using the following information about Project A, its activities and predecessor activities below: Activity Predecessors a. Create the Activity Network Diagram using the (AoN) technique. (Question repeated from Tutorial 3, remove any redundant member) 8. Develop the AOA diagram based on the following information.
