In a manufacturing unit filled with a diverse equipment, it is difficult to identify the faults or defects in the machinery. Hence, to make the task of operators easy, OEE was developed. It is a form of mathematical calculation that helps analyze a machine’s defects and find ways to improvise its functioning. OEE is only a measure to gauge the functioning of machines, but you must find ways to improve overall equipment effectiveness. An increase in the OEE score leads to an enhancement in the functioning of machines in the manufacturing unit.
Before knowing ways to improve OEE, it is essential to understand it briefly.
Overall Equipment Effectiveness (OEE) is a metric that measures the functioning of a running manufacturing unit compared to its full potential.
To simplify, OEE measures the percentage of productive manufacturing time.
The two different methods to calculate OEE are,
#1 Simple Calculation
The formula is,
OEE= (Good Count * Ideal Cycle Time) / Planned Production Time.
#2 Preferred Calculation
The formula is,
OEE= Availability * Performance * Quality.
There are different ways to improve the OEE score, which can either be done by incorporating simple changes or by adopting automation into the practice; a few of the methods are:
Valuing your investments is the primary duty of any person. Equipment is a valuable investment for a manufacturer. OEE score is an indirect measure of the defect in either the machine or the process.
Hence, there is no harm in investing in improving overall equipment effectiveness. However, the manufacturer should always remember, along with investing in the equipment and processes, that he is also increasing his manufacturing business’s shelf life.
