Automated design and optimisation of sensor sets for Condition-Based Monitoring

A software tool was developed for automating the design, optimisation and performance assessment of sensor sets to support the Prognostics and Health Management (PHM) of the Joint Strike Fighter. The software (MADe) is based on a model-based simulation of failure propagation through the various subsystems of the aircraft to generate a system-level failure modes and effects database. The failure database generated by this analysis is used to identify the monitoring requirements of the system to achieve a specified level of failure coverage. This paper outlines the analysis approach and provides a case study to demonstrate the application of automated sensor design and optimisation.
