$[$Supplement $7]$ Bottleneck Analysis

A production system at a manufacturing company is given in the flowchart below. The boring operation occurs separately from, and simultaneously with, the cutting and milling operations. A product needs to go through only one of the four assembly operations. The four assembly operations are in parallel.

Answer the following questions based on the flowchart.

Write your final answer only $($without intermediate steps$)$ for the fill$-$in$-$the$-$blank questions.

Question $10(5$ points$)$

Which operation is the bottleneck?

Question $10$ options:

Assembly

Welding

Milling

Cutting

Boring

Question $11(5$ points$)$

Question $11$ options:

The bottleneck time $=$

minutes per unit. Round the final answer to two decimal places, e$.$g$.,0\mathrm{.}12,$ when necessary.

Question $12(5$ points$)$

Question $12$ options:

For the entire production system, the throughput time $=$

minutes. Round the final answer to two decimal places, e$.$g$.,0\mathrm{.}12,$ when necessary.

Question $13(5$ points$)$

Question $13$ options:

If the company operates $2$ shifts per day, $8$ hours per shift, and $20$ days per month, the capacity of this production system $=$

units per month. Round the final answer to two decimal places, e$.$g$.,0\mathrm{.}12,$ when necessary.
