ZY's director of material management has been named the project manager in charge of automated warehouse system.

The optimistic, most likely, and pessimistic times in weeks) have also been provided for each activity, as shown below.

Can this completion be achieved? Include probability information in your answer. What recommendation do you have if the 40-week completion time is required? (4) Answer: (iii) Suppose that management requests that activity times be shortened to provide a 73 percent chance of meeting the 40-week completion time. If the variance in the project completion time is the same as you found in part (), how much should the expected project completion time be shortened to achieve the goal of a 73 percent chance of completion within 40- weeks? [4] Answer: (iv) Write a short managerial report by taking into consideration the above issues in the models you developed in parts (i), (ii) and (iii).
