Abstract :
This paper is concerned with an approach of risk aversion by possibility theory. We introduce and study new possibilistic risk indicators. The main notions are the possibilistic risk premium and the possibilistic relative risk premium associated with a fuzzy number and a utility function. We also give formulae for computing them. They extend to possibility theory the classic notions of risk premium and relative risk premium. We show by an example how the main possibilistic risk indicators are computed using trapezoidal fuzzy numbers.
