摘要：

The notion of an approximation interval of a fuzzy number is introduced. It is the interval which fulfills two conditions. In the first, its width is equal to the width of a fuzzy number being approximated. In the second, the Hamming distance between this interval. and the approximated number is minimal. The introduced notion is compared with the notion of expected interval of a fuzzy number known in literature. (C) 2001 Elsevier Science B.V. All rights reserved.
