eXpress Diagnostic Metrics and Trade-Off Studies Advanced Diagnostic and Testability Statistics Reports identify the current sensor effectiveness Test Point Placement reports identify best places for additional sensors Fault Detection, Fault Isolation and Fault Localization provide validation of the sensor usefulness Learn more: Trade studies, risk management, simulation, Oh My! New Design Optimization Functional capture allows optimization to begin before failure modes are known, that is "Designing for Testability" Optimization continues as failure modes become known Manages the data and design throughout the entire process Learn more: Optimizing test strategies. Legacy Optimization eXpress can identify where additional information can be obtained from existing sensors When used for legacy designs, the eXpress model does not even require connectivity eXpress's Test Capture capability can be used to model any existing diagnostic conclusions: Artificial Intelligence / Knowledge Base approach Fault-Code Reporting Health-Monitoring Static Tree Dynamic Reasoners etc. eXpress recommends new optimized sensor points based on the existing system (including the existing diagnostics) Learn more: Legacy Optimization Used for Shuttle Upgrades View the OMS/RCS Sensor Optimization Study by Lockheed Related Links: How does eXpress differ from other tools?
