On the valuation of alternatives for decision-making under uncertainty

We focus on the problem of decision-making in the face of uncertainty. The issue of the representation of uncertain information is considered and a number of different frameworks are described: possibilistic, probabilistic, belief structures, and graded possibilistic. We suggest methodologies for decision-making in these different environments. The importance of decision attitude in the construction of decision functions is strongly emphasized.
