Safety analysis Training - FMEA/FMEDA/FTA
2018.09.14

FMEA: Failure mode and effect analysis. By applying FMEA at different levels of the item, functional safety requirements, technical safety requirements, software safety requirements and hardware safety requirements can be obtained.

 

FMEDA: Failure mode, effect and diagnostic analysis. This method can be used to calculate the random hardware failure rate, estimate the single point fault matrix and latent fault matrix with security mechanism applied.


FTA: Fault Tree Analysis. This analysis method can help to evaluate the effect of random hardware failure rate on the safety goals. Through fault tree analysis and taking considerations of safety mechanisms, the evaluation of random hardware failure involving in violation of safety goals is obtained.
