Question: 24 points

The following jobs are waiting to be processed at Rick Carlson’s machine center. Carlson’s machine center has a relatively long backlog and sets fresh schedules every 2 weeks, which do not disturb earlier schedules. Below are the jobs received during the previous 2 weeks. They are ready to be scheduled today, which is day 241. At this time, no other jobs are in process or waiting to be worked.

Job Date Job Received Production Days Needed Date Job Due
A 5 28 35
B 9 12 70
C 10 36 51
D 12 45 62
E 17 18 89
  1. For the following 3 sequencing rules, compute the average flow time from today (consider that today, which is day 241, is day 1 for determining flow time), average days late (with no credit for being early) and average days early (with zero days early for a job that is late). The rules are the following:
  • FCFS (First Come First Served)
  • EDD (Earliest Due Date)
  • SPT ( Shortest Processing Time)
  • CR (Critical Ratio)

b) Which rule would you recommend using? Why?
