Abstract: This paper provides the expected value models for the optimal problem of the combined securities in which profit rates and risk rates are fuzzy variables.A fuzzy simulation based on genetic algorithm for solving the expected value models with fuzzy parameters is also documented and illustrated by numerical examples.

Key words: combined securities, expected value models, fuzzy simulation, genetic algorithms
