The variational iteration method for fuzzy fractional differential equations with uncertaintyDOI: 10.1186/1687-1812-2013-13 Keywords: fuzzy number, fuzzy initial value problems, Riemann-Liouville fractional derivative, Mittag-Leffler function, variational iteration method Abstract: In this paper the variational iteration method is used to solve the fractional differential equations with a fuzzy initial condition. We consider a differential equation of fractional order with uncertainty and present the concept of solution. We compared the results with their exact solutions in order to demonstrate the validity and applicability of the method.
