How to Calculate Operator Efficiency in the Garments Industry?
Garments Manufacturing is a fully manual and human work process. Sewing is the main section, it’s based on a lot of sewing machines in the sewing line. Every machine requires a sewing operator. The efficiency of the sewing operator is key here for better productivity in the garments industry. In this article, we discuss How to Calculate Operator Efficiency in the Garments Industry.
Operator efficiency in the garment industry is a measure of how productive an operator is compared to the standard time allowed for a particular task. A higher efficiency indicates the operator is producing garments close to the ideal rate.
How to Calculate Operator Efficiency in Garments
Formula: To calculate the operator efficiency following formula should be followed by any industrial engineer. Operator efficiency (%) = Total minute produced by an operator/ Total minute attended X 100
- Where,
Total minute produced=Total piece made X SAM of the operation (Cutting or Sewing) &
Total minutes attended=Total hours worked in the machine X 60 - To collect the data following step should be done using in operator efficiency formula.
1st step:
On a definite operation firstly we have to know the SAM of that operation. By counting the time using a stopwatch we can collect this data.
2nd step:
Secondly, we have to know how many piece he or she made on that SAM. Counting the total piece of garments after SAM of any operation we can get it.
3rd step:
Then we also have to mark that how many hours he or she worked on that machine. From the shift hours, we can assume this time. Usually, 8 hours is in a shift.
Then from the above all data finally we can find the operator efficiency by using the operator efficiency calculation formula at work. We have to also consider that an operator doesn’t spend all the time in a machine. In that case, we have to minus the time that he or she spends on doing other things like lunch, going to the toilet, etc. Example:
An operator was doing an operation of SAM for .50 minutes. In 8 hours shift day, he produces 400 pieces. So according to the efficiency calculating formula, we can put this info below like this formula.
Efficiency at work= (400 X .50)/(8X60) * 100=200/480 *100=0.4167*100=41.67 %
For exercise:
1. An operator was doing an operation of SAM for 0.40 minutes. In 8 hours shift day, he produces 350 pieces. Find out the operator’s efficiency at work.
Answer: 29.17%
2. An operator needs 0.45 minutes to sew a garment. He spent 8 hours on that machine and produced a total of 380 pieces of garments. So what will be the operator’s efficiency at work? You can calculate and let us know in the comment box.
Conclusion
The main objective of the IE department in the garments industry is to increase operator efficiency. A comprehensive strategy incorporating technology, process improvement, training, and a positive work atmosphere is needed to increase operator efficiency. The productivity and quality of clothing manufacturers can be significantly increased by consistently improving these factors.
