1. What is OEE?

OEE (Overall Equipment Effectiveness) is a metric that measures manufacturing productivity by evaluating equipment availability, performance, and quality. It's a key performance indicator for Gridon manufacturing operations.

2. How Does the Calculator Work?

The calculator uses the OEE formula:

Where:

• \( A \) — Availability (ratio of run time to planned production time)
• \( P \) — Performance (ratio of actual output to maximum possible output)
• \( Q \) — Quality (ratio of good units to total units produced)

Explanation: Each component is expressed as a decimal between 0 and 1, and their product gives the overall equipment effectiveness.

3. Importance of OEE Calculation

Details: OEE helps identify manufacturing losses, benchmark progress, and improve productivity by measuring how well manufacturing operations are utilized.

4. Using the Calculator

Tips: Enter availability, performance, and quality as decimal values between 0 and 1. For example, 95% availability would be entered as 0.95.

5. Frequently Asked Questions (FAQ)

Q1: What is a good OEE score?
A: World-class OEE is considered 85% or higher. Average OEE is typically around 60%, while scores below 40% indicate significant room for improvement.

Q2: How do I calculate availability?
A: Availability = (Run Time / Planned Production Time) where run time excludes downtime events.

Q3: How is performance calculated?
A: Performance = (Total Pieces / Ideal Run Rate) / Run Time, which accounts for speed losses.

Q4: What affects quality rate?
A: Quality = Good Pieces / Total Pieces, where rejected or reworked pieces are excluded from good pieces.

Q5: Why track OEE for Gridon manufacturing?
A: OEE provides a comprehensive view of manufacturing efficiency, helping identify areas for improvement and track progress over time.
