\subsection{FMEA - General Criticism}
|
|
|
|
\begin{itemize}
|
|
\item FMEA type methodologies were designed for simple electro-mechanical systems of the 1940's to 1960's.
|
|
\item Reasoning Distance - component failure to system level symptom
|
|
\item State explosion - impossible to perform rigorously
|
|
\item Difficult to re-use previous analysis work
|
|
\item Very Difficult to model simultaneous failures.
|
