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). 7 units/hr 5 units/hr Assembly 0.8 units/hr Sawing Sanding Welding Assembly 2.1 units/hr 0.8 units/hr Drilling 2.5 units/hr Assembly 0.8 units/hr a) V is the bottleneck. b) The bottleneck time is minutes per unit (round your response to two decimal places).

Question
Transcribed Image Text:### Production Process Flowchart at Kenneth Day Manufacturing
The flowchart illustrates a production process with multiple stages at Kenneth Day Manufacturing. The process consists of several operations with different production rates, where:
- **Sawing**: 7 units per hour.
- **Sanding**: 5 units per hour.
- **Drilling**: 2.5 units per hour.
- **Welding**: 2.1 units per hour.
- **Assembly (three parallel lines)**: Each line operates at 0.8 units per hour.
The drilling operation occurs separately but simultaneously with the sawing and sanding, which are consecutive operations. A product is required to pass through only one of the three parallel assembly operations.
#### Questions:
a) Identify the bottleneck operation.
b) Calculate the bottleneck time in minutes per unit (rounded to two decimal places).
c) Determine the throughput time of the overall system in minutes (rounded to two decimal places).
