A linear regression model using triangular fuzzy number coefficients

Fuzzy regression analysis using fuzzy linear models with symmetric triangul ar fuzzy number coefficients has been formulated earlier. The goal of this regression is to find the coefficients of a proposed model for all given in put-output data sets. In this paper, we extend the results of a fuzzy linea r regression model that uses symmetric triangular coefficient to one with n on-symmetric fuzzy triangular coefficients. This work eradicates the inflex ibility of existing fuzzy linear regression models. (C) 1999 Published by E lsevier Science B.V. All rights reserved.
