1. Consider the following tasks that must be assigned to four workers on a conveyor--paced assembly line (i.e., a machine--paced line flow). Each worker must perform at least one task.
2. Time to Complete Task (seconds):
3. Task 1:26
4. Task 2: 25
5. Task 3: 15
6. Task 4: 19
7. Task 5: 15
8. Task 6: 20
9. Task 7: 49
10. Task 8: 15
11. Task 9: 20
12. Task 10:25
13. Task 11: 15
14. Task 12: 20
15. The current conveyor--paced assembly-line configuration assigns the workers in the following way:
16. Worker 1: Tasks1, 2, 3
17. Worker 2: Tasks 4, 5, 6
18. Worker 3: Tasks 7, 8, 9
19. Worker 4: Tasks 10, 11, 12
20. Assume a demand rate of17 units per minute. What would be the target manpower?
