A Not on the Value Approximation of Fuzzy Systems Variables

Under the maxmin compositional rule of inference which is used in applications while executing fuzzy algorithms, Pappis showed that the property of approximation is preserved. In this paper, we generalize a measure of proximity of fuzzy subsets on any set, without the restriction of finiteness. And it is shown that the same property of approximation if preserved under the supmin compositional rule of inference.
