Data Trend from NEXIO SYSTEM - Oct, 2020

To achieve everyday production target, factory is conducting several activities such as, time study, line balancing, and training to the operator. However, have you ever seen the data of the sewing machine operation ratio?
We understand this situation that we cannot be able to visualize the data is an issue. To visualize and analyze, we have conducted survey in the market and collected over 100 factories with total 760 machine data.

To segregate sewing operation, there are 3 types of time.
1. Needle time
2. Handling time
3. Other

We think ratio of the those 3 are related to the health of factory production strongly.Each factory should have trend of the operation ratio and that number must have variety of the reasons depending on the factory or production line.To mention several types of reasons of less operation ratio are, operator might be waiting for next pieces, operator is not skilled to produce stably, or might be the health condition of the operator is not well.

The key is, 1st we need to grasp the hourly or daily changes of production on real time basis and once there is problem we take immediate action for the improvement.

Left chart is a data which Brother has analyzed from the 1-Line assessment through 90 factories. To study this histogram, we can see there are 2 condensed areas.1 is below average around 40% to 60% of operation ratio. The other is between 60% to 80%.Use as your reference of 1-Line Assessment result to judge whether your operator is utilizing equipment properly or not.
