Actual Output (units):

Potential Output (units):

Efficiency (%):

Assembly line efficiency is a critical measure of how well a manufacturing process converts raw materials into finished products. High efficiency indicates that the assembly line is functioning optimally, with minimal waste and maximum output. Understanding and improving efficiency can lead to significant cost savings and productivity gains.

## Formula

The efficiency (EEE) of an assembly line can be calculated using the formula:

E=(AOPO)×100E = \left( \frac{AO}{PO} \right) \times 100E=(POAO​)×100

where:

• EEE is the efficiency (%)
• AOAOAO is the actual output (units)
• POPOPO is the potential output (units)
