Correlation and information energy of interval-valued fuzzy numbers
In this paper, we introduce the correlation coefficient of interval-valued fuzzy numbers, and study some of their properties. Furthermore, we put forward the concept of information energy, and how to compare interval-valued fuzzy numbers by applying them. (C) 1999 Elsevier Science B.V. All rights reserved.
