Question:
16. On a busy day in June, the Framkrantz Factory had five jobs lined up for processing at machine center 1. Each job went to machine center 2 after finishing at machine center 1. After that they had different routings through the factory. It is now shop day 83 and shop day due dates have been established for each job. Machine time includes setup time, but it takes one day to move between centers and two days of queue time at each center after machine center 1 (including Finish).
a. Use a spreadsheet program to calculate the priorities for each job using the critical ratio rule.
b. All jobs were at machine 2 by the morning of shop day 96. (Job A took two days instead of one and job D took one day instead of six on machine 1.) Unfortunately, there was a long job on machine 2 and none of the five jobs had started yet. What would their priorities be for machine 2?
c. What would priorities be if job A’s due date were 96 (current date = 96)?
