Multicriteria expected value models in fuzzy decision systems

Based upon the upper expected value, lower expected value and expected value operators of a fuzzy variable, this paper first presents three types of multicriteria maximum expected value models. Then a theorem about the connection of Pareto solutions among the maximum expected value models is proved. In addition, the relationship between maximum and minimum expected value models is discussed. At the end of the paper, a numerical example of maximum expected value model is provided to show our modeling ideas.
