In this article we show how the lottery-dependent expected utility (LDEU) model can be used in decision analysis. The LDEU model is an extension of the classical expected utility (EU) model and yet permits preference patterns that are infeasible in the EU model. We propose a framework of...

In this article, we develop a model that permits a decision maker's preferences to depend on the decision maker's ambiguity about the probability of an event that is relevant for decision-making purposes. We deal with ambiguity about the probability through preference modeling, with ambiguity...

This paper provides an extension of L. J. Savage's subjective expected utility theory for decisions under uncertainty. It includes in the set of events both unambiguous events for which probabilities are additive and ambiguous events for which probabilities are permitted to be nonadditive. The...

A procedure for screening multiattribute alternatives is proposed. This procedure reduces the detailed data collection needs and the information burden on the decision maker. It is shown that the inferior decision alternatives can be excluded without specifying probabilities, importance weights,...
