We study attitudes towards risk in the Rank Dependent Expected Utility (RDEU) model. This model replaces expected utility by another functional, which is characterised by two functions, a utility function on outcomes in conjunction with a probability-perception function. We use the notion of...

Normative models of behaviour under risk in the framework of expected utility (EU) or under uncertainty in the framework of subjective expected utility (SEU) are very limited. In this survey paper, it is shown that non-expected utility (non-EU) models based on the Choquet integral allow for much...

Nous exposons dans cet article les avancees de la theorie de la decision en environnement incertain au cours des vingt dernieres années. plus precisément, nous partons des modeles d'esperance (objective et subjective) d'utilite pour ensuite en presenter les generalisations recentes.

Five different methods of determining sap flow (SF), three based on heat pulse (compensation heat pulse, New Zealand--cHP-NZ; compensation heat pulse, Greenspan/Australia--cHP-G (South oriented), and cHP-G-EW (East and West oriented, average); non-compensation heat pulse, Ariel/Israel--ncHP),...
