In this paper, two kinds of possibility distributions, namely, upper and lower possibility distributions are identi®ed to re¯ect experts' knowledge in portfolio selection problems. Portfolio selection models based on these two kinds of distributions are formulated by quadratic programming problems.

✦ Synopsis
In this paper, two kinds of portfolio selection models are proposed based on fuzzy probabilities and possibility distributions, respectively, rather than conventional probability distributions in Markowitz's model. Since fuzzy probabilities and possibility distributions are obtained depending on possibility grades of security data o ered by experts, investment experts' knowledge can be re ected. A numerical example of a portfolio selection problem is given to illustrate our proposed approaches.

This paper provides new models for portfolio selection in which the returns on securities are considered fuzzy numbers rather than random variables. The investor's problem is to find the portfolio that minimizes the risk of achieving a return that is not less than the return of a riskless asset. The
