Q3) a) Using the data in Table 4, draw the graph of maximum and minimum bounds of possible weekly cash flow by using float management. Hint: Each project needs to be evaluated individually first, then the findings need to be gathered to show the cash flow covering all three projects. b) Draw the graph of maximum and minimum possible weekly labor day requirement. Try to level the labor day requirements to have a least possible variation in the resources. c) Reduce the expected total duration of total completion duration of all three projects by 10-weeks with crashing technique. Draw a graph which shows the reverse correlation between cost and duration for this 10-weeks crashing. Assume that each crashing may reduce the duration by 1 week. Hint: You may crash any activity in any project without any separation between the projects.
