Required:
Question 1) Draw the network (AOA or AON) and find the critical path, time, and cost for an all-normal level of project activity.
Question 2) Calculate the crash cost-per-day (all activities may be partially crashed).
Question 3) Find the optimal way of getting an 18-day delivery time. What is the project cost?
Question 4) Find the optimal way of getting a 16-day delivery time. What is the project cost?
Question 5) Calculate the shortest delivery time for the project. What is the cost?
Solve the given numerical problem and illustrate step by step calculation.
