A model for opinion agreement and confidence in multi-expert multi-criteria decision making

Gerardo Canfora, Luigi Troiano


In multi-expert multi-criteria decision making problems, we often have
to deal with different opinions, different importance of criteria and experts,
missing data, unexpressed opinions and experts who are not fully confident
with their judgment. All these factors make the problem more dificult to
solve, and run the risk of making the model logic less transparent. In this
paper, we present a model based on simple assumptions described by logical
rules, in order to maintain the model transparency and verifiability. In particular
the model explicitly considers the level of agreement of experts, such
as their importance and confidence.
