False Alarm Mitigation Algorithm Suite, Design Guide, and Software Module

Impact Technologies, in collaboration with our F-35 partners, proposes to adapt and demonstrate false alarm mitigation techniques for use in Prognostics and Health Management (PHM) development and verification software. The proposed work will utilize propulsion and drivetrain development data and models and ultimately feed a set of statistical analysis algorithms, a design guide for implementation, and a software module to perform the analysis and assist the developer and design agent. Specifically, the core innovations of this project include: 1) Identifying the technical and procedural sources of false alarms and data, models, and analysis techniques that will be used to mitigate those alarms; 2) Developing rate and time-based false alarm performance metrics for PHM systems; 3) Assessing best technical approaches for design of PHM using limited sources of fault data and physics-of-failure models; and 4) Producing a portable software module encapsulating the algorithms and statistical analysis package. This program impact is significant and entirely integral with the JSF PHM objectives including: mitigating both the military's and supplier's risk of high false alarm rates, enabling effective autonomic logistics and performance-based contractor logistics support contracts, and maximizing the life cycle cost benefits.
