Some approximations and moments of fuzzy numbers

In this paper, some points and approximately intervals and moments of fuzzy numbers are introduced. These indices play an important role todescriptive of fuzzy numbers. For instance, TheirProperties are obtained to fuzzy Gaussian membership function (fuzzy Gaussian curve) that has manyapplications in models and fuzzy systems. Also the approximation of fuzzy Gaussian membership function is obtained and its properties is studied.
