چکیده (انگلیسی):

In the present paper, using fuzzy Haar wavelets, we introduce an iterative method for numerical solving two-dimensional non-linear Urysohn fuzzy integral equations (2DNUFIE). We define a useful metric to prove the convergence and error estimate of the method. Moreover, we investigate the numerical stability of the presented numerical successive approximations. Finally, numerical experiments show the accuracy of the method.
