Prognostic Reasoning
• Detects out of tolerance conditions for single, multiple and
combinations of data points
• Predicts failures, detects degradation and under performance
• Determines the remaining useful life of components,
equipment, and systems

Condition Monitoring
Condition assessment triggers:
• Control signal
• Reconfiguration for redundant systems, equipment and components
• Provides continuous load balancing
• Enables adjustments for increased efficiency
• Operational Impact Assessment – Operator Dashboard
• Can the system continue to function in a degraded capacity?
• Notification
• Alerts operators, management, and/or dispatch maintenance with specific
required parts and tools
Other options:
• Post Analysis of Failed Components
• Provides critical input to manufacturers for design improvements
