For the information provided below I am trying to find the best scheduling method out of FIFO, EDD, Minimum Slack Time, and Minimum Critical ratio in terms of total lateness for the system.

Sullivan is a plant that runs custom work, but the size of the jobs can vary quite a bit. The plant works an 8 hour day, but with clean-up, actual run time is 7.5 hours. Employees take turns for lunch and breaks so the plant runs the continuous 7.5 hours. Here is the data from the last week. They use a first-come-first-served model. They look at the schedule each day to decide what to schedule for that day. Assume that any order received is not considered for scheduling until the next working day. For example, if they receive an order on Friday, they won't consider it for the schedule until Monday. Orders can be split up-for example, if it is started on Tuesday, it can be finished on Wednesday April Calendar with Dates Customer Jackson Ceaser Martinez Renner Carter Cheadle Liu Khan Rudd Evans Larson Olsen Sunday Monday Tuesday Wednesday Thursday Friday 1 4 4 5 6 7 8 8 11 12 13 14 15 18 19 20 21 22 25 26 27 28 29 Day of the Week Order Date job Received received Friday 16-Apr 16-Apr 16-Apr 16-Apr 16-Apr Monday 19-Apr 19-Apr 19-Apr Tuesday 20-Apr 20-Apr 20-Apr 20-Apr 20-Apr Wednesday 21-Apr 21-Apr Thursday 22-Apr 22-Apr 22-Apr 22-Apr 22-Apr Friday 23-Apr 23-Apr 23-Apr 23-Apr 23-Apr Saturday 2 3 9 9 10 16 17 23 24 30 Estimated Processing Time (in Desired hours) ) Due Date 3.6 19-Apr 1.6 19-Apr 1.6 19-Apr 2 2 19-Apr 2 19-Apr 4 20-Apr 2.8 20-Apr 2 20-Apr 3.2 21-Apr 4.4 22-Apr 4 21-Apr 7.6 23-Apr 3.6 22-Apr 2.8 23-Apr 1.6 22-Apr 2.4 28-Apr 2 23-Apr 3.6 23-Apr 2 27-Apr 2 26-Apr 2.5 26-Apr 1.85 26-Apr 2 27-Apr 3.2 26-Apr 1.6 27-Apr Pace Saldana West Rooker Boseman Gillan Kapoor Yeun Appleton Coogler Brolin Yeoh Stewart 6 Sullivan is a plant that runs custom work, but the size of the jobs can vary quite a bit.
