The Variational Iteration Method for Solving Fuzzy Duffing's Equation

Abstract

In this paper, we use the Variational Iteration Method (VIM) to find the approximate analytical solution for an initial value problem involving the fuzzy Duffing ordinary differential equation. VIM allows for the solution of the differential equation to be calculated in the form of an infinite series in which the components can be easily computed. Numerical examples were solved to illustrate the capability of VIM in this regard.
