In this paper the idea of an approximation interval method of a fuzzy number is used for supplier selection. This is the interval that fulfils two stipulations. at the beginning, its distance is the same as the distance of a fuzzy number existing approximated. Next, the Hamming approximation among this distance and the approximated data is minimum. We obtain formula of defining the approximation distance for a fuzzy data presented in a basic kind as well as for a fuzzy number of L-R type. In practice, fuzzy intervals are frequently used to represent uncertain or imperfect information.
