Reliability Knowledge Base for Engineers and Decision Makers

Key Definitions

• Asset Health (AH): Condition indicator of whether assets can continue operating safely and reliably.
• Risk-Based Inspection (RBI): Inspection planning from both probability and consequence of failure.
• Predictive Analytics: Statistical forecasting of future asset behavior and failure trends.
• Reliability Assessment: Structured analysis for maintenance, capital, and compliance decisions.

Method Overview

1. Collect and standardize operating and asset data.
2. Classify degradation mechanisms and uncertainty drivers.
3. Apply probabilistic models for risk and condition trajectories.
4. Convert outputs into inspection and intervention plans.

Common Use Cases

• Prioritizing inspections across large asset portfolios.
• Estimating short and long-term failure projections.
• Improving maintenance strategy in data-limited contexts.
• Supporting audit readiness with documented analytics logic.

Implementation Notes

• Start with a scoped pilot on critical assets.
• Align model outputs with business decision thresholds.
• Use periodic recalibration as new data is collected.
• Integrate outputs into maintenance and integrity workflows.
