The production manager must determine the processing sequence for five jobs through two machines (M1 and M2). The same sequence will be allowed in both departments. The manager's goal is to move the jobs through the two departments as quickly as possible.

Processing Time (hours)

JOB	M1	M2
A B C D E F	10 8 4 9 7 6	8 5 6 3 8 4

1. Determine the optimal sequence using Johnson's Rule. (1 point)
2. Draw a Gantt chart with this optimal sequence and find total completion time and total idle time. (3 points)
3. Find the flow times of all the jobs on M1 and M2 using the optimal sequence. (1 point)
