the expected value nash equilibrium strategy of the fuzzy games

In this paper, firstly, we obtain the credibility measure of fuzzy heptagonal variables. also, we attain the expected value of fuzzy heptagonal variables. then, based on these theorems, we present the expected value nash equilibrium strategy of the fuzzy games. we extend the expected model to fuzzy heptagonal variables and improve the previous researches in this area. in this article we focus on a class of non-cooperative games namely two-person zero-sum matrix games.
