a. Develop separate schedules by using the FCFS and EDD rules. Compare the schedules on the basis of average flow time and average days past due.

Using the FCFS (first come, first served) decision rule for sequencing the customers, the order is:

Sequence	1	2	3	4	5
Customer

Using the EDD (earliest due date) decision rule for sequencing the customers, the order is (to resolve a tie, use the order in which the jobs were received):

Sequence	1	2	3	4	5
Customer

The average flow time and average days past due for each option are: (Enter your responses rounded to one decimal place.)

Rule	Average Flow Time	Average Days Past Due
EDD	______	_______
FCFS	______	_________

b. On the basis of average flow time, which rule gives the best schedule?

On the basis of average days past due, which rule gives the best schedule?

Currently a company that designs Web sites has five customers in its backlog. The time since the order arrived, processing time, and promised due dates are given in the following table. The customers are ready to be scheduled today, which is the start of day 190. Time Since Order Arrived (days ago) Customer Processing Time (days) Due Date (days from now) 100 26 50 26 28 66 a.
