Modelling And Initiating Knowledge Manegement Program Using Corralation Coeficient Between Fuzzy Numbers

Abstract

When we deal with crisp data, it is very common to find the correlation between variables. Here, we propose a method to calculate the
correlation coefficient for fuzzy data, but rather than defining the correlation on the intuitionistic fuzzy sets like most of the previous works, we
adopt the method from central interval. This interval can be used as a crisp set approximation with respect to a fuzzy quantity. This indices can be
applied for comparison of fuzzy numbers namely fuzzy correlations in fuzzy environments and expert’s systems. Finally some of their applications
are mentioned
