How to Calculate Efficiency of a Production Line?

To know the performance of a garment factory, and a comparative study of the sewing line performance, we measure production line efficiency. So, like individual operator efficiency, measuring the efficiency of a production line is important for a factory. Daily line efficiency shows line performance.

Production Line Efficiency Calculation - Information required

To calculate the efficiency of a line for a day, you will need the following data (information) from the line supervisor or line recorder.

1. Number of operators – how many operators worked in the line in a day

2. Working hours (Regular and overtime hours) – how many hours each of the operators worked or how many hours the line run in a day

3. Production in pieces – How many pieces are produced or total line output at the end of the day

4. Garment SAM – What is the exact standard minute of the style (garment)

Once you have above data you have to calculate following using above information -
 a. Total minutes produced by the line: To get total produced minutes, multiply production pieces by garment SAM
 b. Total minutes attended by all operators in the line: Multiply the number of operators by daily working hours and convert total hours into total minutes (multiplying by 60).

Now, calculate line efficiency using the following formula:


Line efficiency (in percentage) = (Total minutes produced by the line *100) /(Total minutes attended by all operators)

An Example - Calculating Production Line Efficiency

Let's calculate the line efficiency of one production line.
48 operations worked in a line for 8 hours. They produced 160 garments and SAM of the garment is 44.25 minutes.

Here,
Total minutes produced = (160 x 44.25) = 7080 minutes
Total minutes attended = (48 operator x 8 hours x 60) = 23040 minutes
Effiicnecy% = (7080 x100)/23040 % = 30.729%

For more example, refer to the following table. Data calculation formula has been given on the header row of the table.
