MULTI-OBJECTIVE PORTFOLIO SELECTION PROBLEMS IN A SOFT COMPUTING FRAMEWORK
José Vicente Segura, José D. Bermúdez, Enriqueta Vercher
In this paper we present a multi-objective decision approach for the fuzzy portfolio selection problem, assuming that uncertainty is modeled by means of fuzzy logic. Specifically, we approach the uncertainty on the future returns of the investment using LR-fuzzy numbers and consider some f-weighted interval-valued possibilistic moments to approximate the return and risk of a given portfolio. A genetic procedure finds the efficient frontier of certain possibilistic mean-downside risk-skewness models. A numerical experiment is reported for assets from the Spanish stock market.
