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?

Notes: Process capacity is the minimum of milling, assembly, and finishing capacity; milling, assembly, and finishing each have one machine / resource.

Milling capacity should be stated in tables per minute, where a table requires one table top and one table stand. Note that the same milling machine makes both table tops and table stands but incurs setups before production of each batch. The batch of tables is the same as the batch of tops and the batch of stands. You should not calculate milling capacity for tops and for stands separately. Instead the milling capacity = batch size / production cycle length, where the production cycle consists of setup for tops, production of batch of tops, setup for stands, production of batch stands. At the end of the production cycle you have enough tops and stands to make a batch of tables.

Group of answer choices

The capacity of finishing determines the capacity of the process.

The capacity of milling determines the capacity of the process.

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

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