Numerical Solution of Fuzzy Differential Equations by Variational Iteration Method

In this paper, variational iteration method is presented to solve the linear and nonlinear fuzzy differential equations. This technique provides a sequence of functions which converges to the exact solution of the problem. Sufficient condition for convergence of the proposed method is given and also a maximum absolute truncation error is estimated. This method provides remarkable accuracy in comparison with the analytical solution. Several numerical examples are given to illustrate the efficiency and performance of the presented method.
