Fault injection is an effective method for PHM and testability validation. However, with the increasing complexity of structures and functions, and with the promotion of integration levels for airborne prognostics and health management (PHM) and integrated modular avionics (IMA) systems, fault injection is often difficult to use in conventional “plug,” “probe,” or “adaptor plate” methods. Fault injection...
In order to achieve effective fault injection and support the fault diagnosis verification for PHM (Prognostics & Health Management), a method for importance analysis of failure mode based on EDA simulation is introduced. In this paper, the influence factors of failure mode importance (Effect Severity Ranking (ESR); Occurrence Probability Ranking (OPR); Detection Difficulty Ranking (DDR)) are...
