I have recently been going through the different methods of calculating efficiencies. I came across the following which, when used with root cause anyalsis can pick up your problems areas in the plant.

Thanks Ajay. But the procedure explained is for a single machine. I am looking for a procedure to calculate the OLE - i.e a combined OEE for a group of machines in a single piece manufacturing flow line.

Overall Equipment Effectiveness = Plant Availability x Quality Rate x Production Performance Rate

Quality Rate = Good Product Produced /Total Product Produced

Availability = (Total Scheduled production time - Downtime) / Total Scheduled Production Time

Production Performance = Total Output /Potential Output,
(Where Potentional output = Rate Speed x Scheduled Production Time)

Hope this helps

Regards,
Ajay
