Q$3)$uestion: Production Line Efficiency Analysis

A manufacturing company operates a production line for assembling electronic gadgets. The line consists of four key stages: Component Assembly, Quality Testing, Packaging, and Final Inspection. The diagram below illustrates the time taken for each stage per unit and the number of units that can be processed simultaneously at each stage.

Component Assembly: $10$ minutes per unit, $5$ units simultaneously

Quality Testing: $15$ minutes per unit, $3$ units simultaneously

Packaging: $5$ minutes per unit, $10$ units simultaneously

Final Inspection: $8$ minutes per unit, $4$ units simultaneously

Diagram Requirements:

A linear representation of the production line showing each stage.

Time per unit and simultaneous capacity for each stage.

A flow from left to right indicating the progression of units through each stage.

Calculation Task:

Calculate the throughput time for a single unit and the bottleneck of the production line.
