Estimating the expected value of fuzzy random variables in random samplings from finite populations

In this paper we consider the problem of estimating the expected value of a fuzzy-valued random element in random samplings from finite populations. To this purpose, we quantify the associated sampling error by means of a parameterized measure we have introduced in a previous paper. Keywords: Aumann's integral, expected value of a fuzzy random variable, fuzzy random variable, -mean squared dispersion, random samplings, random set.
