Beta Distributed Preferences in the Comparison of Failure Modes

Annibal Parracho Sant'Anna, Eduardo Ferraz Martins, Gilson Brito Alves Lima, Renato Alves da Fonseca
2015 Procedia Computer Science  
The risks according to each of nine criteria are evaluated for ten failure modes by a set of seven evaluators.  ...  The probabilistic transformation of CPP employs a beta distribution, whose parameters are estimated on the basis of the means and modes of the samples of seven evaluation values.  ...  Starting from the identification of potential failure modes, CPP-Hi is based on the assessment of risks in accordance with an expanded collection of criteria.  ...
