Application of gaussian quadratures in solving fuzzy fredholm integral equations

Abstract

In this paper first of all the integral term in the fuzzy Fredholm integral equation (FFIE) is approximated by one of the Gaussian methods. FFIE is transformed to a dual fuzzy linear system that it can be approximated by the method that proposed in [7]. In the special case, Chebyshev-Gauss quadrature is applied to approximate the mentioned integral. © Springer-Verlag Berlin Heidelberg 2010.
