What this term means in maintenance
An Asset Health Index is a combined score or classification representing the condition, performance, reliability, and risk of an asset.
Possible inputs
An Asset Health Index may combine:
- Condition readings
- Inspection results
- Failure history
- Age
- Operating load
- Maintenance history
- Performance
- Obsolescence
- Environmental exposure
Practical example
A transformer health index combines oil condition, insulation tests, loading, age, failures, and inspection findings.
Scoring
The method should define weights, thresholds, missing-data rules, and the meaning of each health band.
How the index is used
It may support inspection, maintenance, renewal, capital planning, and risk review.
Important limitation
A single score can hide the specific condition driving risk. Users should be able to see the underlying factors.
Common mistake
Presenting a precise score from poor or outdated data creates false confidence.
