20 points Consider a project with the activity precedence relationships and time estimates given in the following table (20 points) Activity Predecessor 5 Duration 8 B 8 AB 8 D 10 E CD 20 Two workers are available. Due to his skill set, Jack is responsible for activities and Similarly, only Amy can do activities A D and E. 01) Assuming that the time estimates are perfectly accurate, what is the expected project duration during the critical path method taking into the local and resource constraints? Explain. (3 points) 02) Use the ideas from the Critical Chain to reformulate the project schedule using project and feeding buffers. Use the format shown in the lecture slides to represent the critical chain. (3 points) Q3) Assume Jack and Amy can be cross trained to do any activity, but will not share activities. Can the activities be reassigned to Jack and Amy such that the project is complete in less time? If so, indicate the new assignment and project duration (7 points) 04) Consider the following assignment Jack does activities A and D. Amy does activities B, C and EUse the ideas from the Critical Chain to reformulate the project schedule using project and feeding buffers.
