To List members interested in a criticizing viewpoint of TMR:

Over the years I have published several papers comparing Safety Instrumented Systems. One topic addressed is called THE FALLACY OF TMR (yes, I'm shouting). The most current paper "Probabilistic Risk Assessment of Equipment Safety Systems" is available as a reprint from:

The Journal of the System Safety Society. Volume 35, Number 3, Third Quarter 1999.

Alternatively, I can provide you with a copy.
