How to Calculate OEE?

Step-by-Step Guide to Calculating Overall Equipment Effectiveness (OEE)

Now that we know what is overall equipment efficiency we need to know how to proceed in managing it. Calculating Overall Equipment Effectiveness (OEE) involves three key components: Availability, Performance, and Quality. Here’s a step-by-step guide to ensure you get an accurate OEE score for your manufacturing operations:

1. Measure Equipment Availability:

• Definition: Availability measures the percentage of scheduled time that the equipment is available for production.

• Calculation: Determine the total operating time by subtracting downtime from the planned production time.

• Formula: Availability = (Operating Time / Planned Production Time) × 100

2. Assess Performance Efficiency:

• Definition: Performance evaluates how well the equipment is performing when it is running.

• Calculation: Compare the actual output to the maximum possible output.

• Formula: Performance = (Actual Output / Maximum Possible Output) × 100

3. Evaluate Product Quality:

• Definition: Quality measures the percentage of good parts produced versus the total parts produced.

• Calculation: Calculate the ratio of quality products to the total products produced.

• Formula: Quality = (Good Parts Produced / Total Parts Produced) × 100

4. Calculate the Overall Equipment Effectiveness (OEE):

• Definition: OEE combines the three metrics (Availability, Performance, Quality) into a single percentage.

• Calculation: Multiply the three percentages together and divide by 100^2.

• Formula: OEE = (Availability × Performance × Quality) / 10000

By following these steps, manufacturers can obtain a clear and comprehensive picture of their equipment effectiveness, allowing them to identify areas for improvement and implement strategies to enhance their OEE.

Formulas for Availability, Performance, and Quality

Availability Formula

Availability measures the percentage of scheduled time that the equipment is available for production. It accounts for downtime losses such as equipment failures or adjustments.

Formula: 

Calculation Example: If the planned production time is 480 minutes and the equipment was down for 60 minutes, the operating time is 420 minutes.

Performance Formula

Performance measures the speed at which the equipment operates as a percentage of its designed speed. It accounts for speed losses like slow cycles or small stops.

Formula: 

Calculation Example: If the maximum possible output is 1000 units and the actual output is 850 units,

Quality Formula

Quality measures the proportion of good units produced versus the total units produced. It accounts for quality losses like defects and rework.

Formula: 

Calculation Example: If the total units produced are 950 and 50 units are defective,

These formulas provide a detailed breakdown of each component of OEE, helping manufacturers to pinpoint specific areas of loss and target their improvement efforts more effectively.

Strategies for Improving OEE

Identifying and Addressing the Six Big Losses

The Six Big Losses are common causes of inefficiency in manufacturing that directly impact OEE. These include Equipment Failures, Setup and Adjustments, Idling and Minor Stops, Reduced Speed, Process Defects, and Reduced Yield. To improve OEE, it’s essential to identify and address these losses systematically. Start by using real-time data collection to monitor and categorise downtime and inefficiencies. Analyse this data to pinpoint the most frequent and impactful issues. Implement corrective actions such as preventive maintenance for equipment failures and standardised work procedures to minimise setup times. By targeting these specific areas, manufacturers can significantly reduce losses and enhance their OEE.
