Anomaly Detection Predicts System Failure
The anomaly detection algorithm assesses the overall probability of systematic failure in complex systems. The fault detection algorithm uses both physical and statistical data in tandem to assess the systematic risk value which reflects the overall probability of system failure in complex systems. The overall risk measure is a disjunction over all failure modes of the system.

Hybrid-Logic Algorithm Combining Statistical and Physical Data
Unlike current systems which use statistical inputs to derive failure probability, the hybrid-logic based algorithm combines statistical data with domain information, causal and functional, to diagnose complex anomalies. The described algorithm not only works well for simple and causally complex systems, but also for functionally complex systems where current state of the art Bayesian networks often fail to detect potential anomalies. Potential applications include vehicle health management (e.g avionics) and device maintenance (e.g biomedical).
BENEFITS OF HYBRID-LOGIC ALGORITHM FOR FAULT DETECTION:
- The algorithm for fault detection uses both physical and statistical data to assess the probability of failure in complex systems.
- High performance levels in simple, causally complex and functionally complex systems.
- Potential applications include vehicle health management (e.g avionics) and device maintenance (e.g biomedical).
