The fault tree analysis qualitatively evaluates the proposed inter-process correlation model based fault diagnosis.
In-vitro diagnostics validation might require some 450,000 patient data sets for algorithm development and validation to ensure there are ample sample sizes in the fault tree analysis.
For ASIL decomposition and allocation, the correlations of the component functions that are necessary for realizing the safety goals need to be modeled using a fault tree analysis. As described above, ASIL decomposition is only permissible if the previous analysis ensures sufficient independence, after which it can be modeled in the fault tree analysis.
