Process Interruptions / Batching - Setup Time: C&A Furniture uses a four-step process to make its famous wood table:

Process / Processing Time (minutes)

Millingtable top 10

Millingtable stand 5

Assembly 15

Finishing 20

There is one milling machine used to mill table top and table stand; one table top and one stand is needed to make each table.

The milling machine requires a setup time of 30 minutes to make table tops and a changeover time of 30 minutes to make table stands. You may assume that, after a setup, the milling machine works on one batch of table tops, and after the changeover time, it works on one batch of table stands; this production cycle then is repeated.

Which of the following conclusions can be drawn?

A.) The capacity of finishing determines the capacity of the process.

B.) The capacity of milling determines the capacity of the process.

C. ) If batch size is greater than 12, the bottleneck of the process will shift from milling to finishing.

D. ) If batch size is greater than 10, the bottleneck of the process will shift from milling to finishing.
