Guide to using Overall Equipment Efficiency Calculator (OEE)
- Input the actual operating time of the equipment in hours. This represents the total time the equipment is actively in operation.
- Enter the planned production time in hours. This is the expected or scheduled time for production.
- Provide the actual output of the equipment in units during the specified operating time.
- Specify the theoretical output, which is the anticipated number of units the equipment should produce during the planned production time.
- Enter the quantity of good products the equipment produces during the operating time.
- Enter the total number of output products produced, including both good and defective items.
- After filling in all the required fields, click the “Calculate” button. The calculator will process the data and provide results for Availability, Performance, Quality, and Overall Equipment Efficiency (OEE).
- If you want to perform new calculations, you can click the “Reset” button to clear the inputs and start fresh.
Formula Used for the Calculator
OEE = A (Availability) × P (Performance) × Q (Quality)
Where:
- A = Operating time / Planned production time × 100
- P = Actual output / Theoretical output × 100
- Q = Good products / Total products × 100
What is Overall Equipment Efficiency?
Overall Equipment Efficiency (OEE) is a key performance metric that measures the effectiveness of a manufacturing process or equipment.
It provides insights into how well equipment is utilized by considering three factors: Availability, Performance, and Quality.
The formula is OEE = A × P × Q, where A is Availability, P is Performance, and Q is Quality.
