A production process at Kenneth Day Manufacturing

is shown in Figure S7.9. The drilling operation occurs separately

from, and simultaneously with, the sawing and sanding operations.

A product needs to go through only one of the three assembly

operations (the operations are in parallel).

a) Which operation is the bottleneck?

b) What is the bottleneck time?

c) What is the throughput time of the overall system?

d) If the firm operates 8 hours per day, 20 days per month, what

is the monthly capacity of the manufacturing process?

Sawing 6 units/hr

sanding 6 unity/hr

drilling 2.4 units/hr

all going into welding 2 unitys/hr

than from that goes

assembly 0.7 unity/hr

assembly 0.7 units/hr

assembly 0.7 unity/hr

so there are three assembly areas
