Risk, ambiguity, and the Savage axioms . We will see further that the additivity of a set function representing a preference relation is linked to the so called sure thing principle. Therefore, we are naturally led to introduce non additive set functions when dealing with uncertainty. We will also see the advantage of using non additive set functions in multicriteria decision making. Risk, ambiguity, and the Savage axioms .
Uncertainty is caused by the lack of evidence to support either belief or disbelief.
Let us suppose that you confront two urns containing red and black balls, from one of which a ball will be drawn at random. Risk, ambiguity, and the Savage axioms .
