Quantified human reliability analysis

Available here. Academic paper by Marzio Marseguerra, Enrico Zio, and Massimo Librizzi1 entitled Human Reliability Analysis by Fuzzy “CREAM”

The work uses the the Cognitive Reliability and Error Analysis Method (CREAM) model, which assumes that the human failure probability depends on the level of control a person has over the contextual scenario in which requested to perform. Four modes of control are identified
* Scrambled,
* Opportunistic,
* Tactical,
* Strategic.

The fuzzy approach allows for ambiguity and uncertainty in the calculations.

I must take a closer look at the paper some time.
