ABC Co. makes tables which are sold in kits to be assembled by the customer. The Master Production Schedule calls for the manufacture of 80 and 200 tables in Weeks 5 and 6 respectively:
Week | 1 | 2 | 3 | 4 | 5 | 6 |
MPS Quantity | -- | -- | -- | -- | 80 | 200 |
The components of the table (tops and legs) have the following data:
Operation | Top (1 needed) | ||
Machine | Setup Time (min) | Run Time (min) | |
1 | Saw | 10 | 5 |
2 | Planer | 40 | 20 |
Operation | Leg (4 needed) | ||
Machine | Setup Time (min) | Run Time (min) | |
1 | Saw | 10 | 1 |
2 | Sander | 52.5 | 17 |
The lot size for both tops and legs is 100 units. Lead time for every operation is 1 week. Historically the load proportions on the machines have been as follows:
Machine | Historical Load Distribution |
Saw | 15% |
Planer | 25% |
Sander | 60% |
Standard time to make a table is 100 minutes.
- Using Overall Factors (CPOF) method determine capacity requirements in Week 4 and 5 for individual resources. (3 points)
