Question 3: (a) Explain the following terms in PERT: i. Optimistic time ii. Normal time iii. Pessimistic time iv. Expected time v. Variance in relation to activities. (b) A project schedule has the following characteristics: Activity Time (weeks) Activity Time (weeks) 1-2 4 5-6 4 1-3 1 5-7 8 2-4 1 6-8 1 3-4 1 7-8 2 3-5 6 8-10 5 4-9 5 9-10 7 i. Construct the network ii. Compute the earliest time (E) and latest time (L) iii. Find the critical path

Step 1
Step 1: Identify the activities and their respective time estimates: 1-2: Optimistic time = 5 weeks, Normal time = 6 weeks, Pessimistic time = 7 weeks 1-3: Optimistic time = 5 weeks, Normal time = 6 weeks, Pessimistic time = 7 weeks 2-4: Optimistic time = 6 weeks, Show more…

Problem 4: A project consists of seven activities with the time estimates as follows: a) Construct the PERT/CPM network for this problem. You should draw the network on paper, take a picture, and paste it into sheet 4. All calculation must be done on Excel for verification. (1 point) b) What is the expected project completion time? What is the critical path? (0.5 point) c) What is the probability that the project can be completed within 30 days? (0.5 point)

26. Using the information below, draw an AOA network. Find the path with the longest expected duration, and use it to compute the number of days you would be 95 percent sure the project would be completed. Calculate the slack, earliest start, and latest start times for each activity and show in table form. Does any path come close to causing a problem in determining the probability of project completion based on just using the path with the longest expected duration?
