1. [15%] A company has five jobs awaiting processing at a bottleneck work- station in a production facility. The day the job was received, its processing time and due date are given in the following table. It is now the beginning of day 13. Day Job Job Processing Job Due Job was Received Time (days) Day 1 6 45 B 6 8 28 7 2 23 D 10 9 35 12 1 21 Calculate the average throughput time and, for each job, the number of days overdue using the following priority sequencing rules: (a) First-come-first-serve (b) Earliest due date (c) Shortest processing time (d) Which rule should be used, in your opinion? Why? (e) The head mechanic at the production facility wants to perform mainte- nance on the bottleneck workstation used to process the jobs above. The mechanic insists the maintenance needs to be performed before day 45, and has indicated that the maintenance will take 3 days to complete and will take the workstation offline. Considering it is still day 13, when is the best time to perform the maintenance? (Hint: Treat the maintenance as though it is a new job.)
