for the following project, assume the quantity for the project Equal 37, use LSM to determine the finish date for the project. Productio Activity IPA n Rate Relation [Day/m] A 1 В A 3 FF 2 SS Answer:
Image of Diagram included Using the diagram, find: The critical path. How long it will take to complete the project? How does simulation determine the probabilities of various project completion times? What is "slack" and why is it important? Why is activity-on-arrow (AOA) or activity-on-node (AON) of significant value to the project manager? How is the uncertainty in project scheduling dealt with? Should the critical path activities be managed differently from noncritical path activities? Explain.
