Question

Managerial Report Develop a report that presents the activity schedule and expected project completion time for the warehouse expansion project. Include a project network in the report. In addition, take into consideration the following issues. l. R. C. Coleman's top management established a required 40-week completion time for the project. Can this completion time be achieved? Include probability information in your discussion. What recommendations do you have if the 40-week completion time is required? 2. Suppose that management requests that activity times be shortened to provide an 80 percent chance of meeting the 4O-week completion time. If the variance in the project completion time is the same as you found in part (1), how much should the expected project completion time be shortened to achieve the goal of an 80 percent chance of completion within 40 weeks? 3. Using the expected activity times as the normal times and the following crashing information, determine the activity crashing decisions and revised activity schedule for the warehouse expansion project. Crashed Activity Time (weeks) Cost ($) Activity 4 7 2 8 ,7 4 5 4 4 3 3 A B C D E F G H I J K Normal 1,000 1,000 1,500 2,000 5,000 3,000 8,000 s,000 10,000 4,000 5,000 Crashed 1,900 1,800 2,700 3,200 8,000 4,100 t0,250 6,400 12,400 4,400 5,500

Explanation / Answer
