The machine shop of Reliable Manufacturing has to schedule eight jobs that are to be sent to final assembly for an important customer order. Currently, all eight jobs are in department X and must be routed to department Y after processing. The processing times (in days) for each job in each department follow: Dept/Job Dept. X Dept. Y A B D E F G H 2 2 5 4 7 5 4 10 3 6 3 8 6 6 Develop two schedules for operations in both departments. For your first schedule, use the SPT priority rule (based on X). Your second schedule should be based on Johnson's Rule. Compare the two schedules using average flow time, makespan, and average WIP inventory. Use a Gantt chart to display your schedules (i.e. a timeline).
