OEE Availability
OEE Availability is the proportion of planned production time remaining after equipment stops and other defined availability losses.
What this term means in maintenance
OEE Availability is the proportion of planned production time remaining after equipment stops and other defined availability losses.
Formula
OEE Availability = Run time ÷ Planned production time × 100
Run time = Planned production time - Stop time
Practical example
A line has 480 minutes of planned production and 60 minutes of stop time.
Availability = 420 ÷ 480 = 87.5%
Losses included
Definitions may include breakdowns, setup, adjustments, and other planned-production stops.
Data consistency
Start, stop, planned production time, and exclusion rules must remain consistent.
Common mistake
Excluding selected downtime to improve the result makes OEE unreliable.
How this term differs
OEE Availability is the availability factor within OEE. It is related to Overall Equipment Effectiveness, Quality Rate, and Performance Rate, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.

Overall Equipment Effectiveness
Overall Equipment Effectiveness, or OEE, measures how effectively planned production time is converted into good output by combining availability, performance, and quality.
Equipment Downtime
Equipment downtime is the period when an asset is required or scheduled to operate but is unavailable or unable to perform its intended function.
Minor Stop
A minor stop is a short production interruption that is usually resolved quickly without a full maintenance repair.
Glossary FAQs
- How is OEE Availability calculated?
Run time divided by planned production time.
- What losses reduce OEE Availability?
Breakdowns, setup, adjustments, and other defined stops during planned production.
- Why must stop rules remain consistent?
Changing exclusions makes OEE comparisons unreliable.
