摘要

The aim of this paper first presents a new solution to the SIR model with fuzzy initial value, elementary properties of this new solution are given. We study the application of variational iteration method in finding the approximate solution of SIR model with fuzzy initial value. The presented method have been applied in a direct way without linearization, disretization or perturbation. Result obtained by this method and fuzzy initial value shows that both are in excellent agreement which indicates their affectiveness and reliability.
