Question: In this chapter, we noted that the EDD rule minimizes the maximum job tardiness and maximum lateness, whereas the SPT rule minimizes the average flowtime.

In this chapter, we noted that the EDD rule minimizes the maximum job tardiness and maximum lateness, whereas the SPT rule minimizes the average flowtime. However, neither of these rules minimizes the average lateness or average tardiness. Use the data in problem 10 to do the following:

a. Try to find a sequence that minimizes the average lateness.

b. Try to find a sequence that minimizes the average tardiness.

c. Can you generalize your logic into a rule or procedure that will accomplish these objectives most of the time?

In this chapter, we noted that the EDD rule
