Thus, the Choquet integral can be used as a defuzzifying aggregation tool to deal with data set involving categorical attributes, linguistic variables, and/or fuzzy numbers. A numerical method with the relevant algorithm is developed to estimate the value of the Choquet integral for any given fuzzy-valued function. © 2005 Elsevier B.V.
