Abstract:

 This paper presents a comparison of the two techniques: arithmetic means and expertons, used for
aggregation of experts’ judgments relative to basic events of fault trees. Valuations as confidence
intervals included in [0, 1] have been considered. First, bounds are numbers to one decimal; next,
numbers belonging to [0, 1]. In this last case, R+_expertons concept is used, with a counter-expertise
form proposed. The means technique is well known in practice, but as fault tree is a logical diagram
built by "AND" and "OR" gates, i.e. nonlinear operators, its use leads to wrong results and expertons
technique should be used.
