A production process at Kenneth Day Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel).
A) is the bottleneck.
b) The bottleneck time isminutes per unit (round your response to two decimal places).
c) The throughput time of the overall system is

minutes (round your response to two decimal places).
D) If the firm operates 8 hours per day, 20 days per month, the monthly capacity of the manufacturing process isunits (enter your response as a whole number).
