A Stochastic Soft Constraints Fuzzy Model for a Portfolio Selection Problem

The financial market behavior is affected by several non-probabilistic factors such as vagueness and ambiguity. In this paper wedevelop a multistage stochastic soft constraints fuzzy program with recourse in order to capture both uncertainty and imprecisionas well as to solve a portfolio management problem. The results we obtained confirm the studies carried out in literature addressedto integrate stochastic and possibilistic programming.
