Abstract

In uncertainty situations where knowledge is described by a Dempster-Shafer belief function (which is more general than a probability measure), von Neumann-Morgenstern linear utility theory applies and leads to a generalized expected utility representation of preference which allows for risk-attitude and ambiguity-attitude (pessimism/optimism).
