Abstract: The point of this paper is to present and analyze a numerical method to illuminate fuzzy initial value problems (FIVPs) including nonlinear fuzzy differential equations. The primary thought is based reformulate the six stages Runge Kutta strategy of order five (RK65) from crisp case to fuzzy case by taking the advantage of fuzzy set theory properties. It is appeared that the comes about demonstrate that the strategy is exceptionally compelling and basic to apply and fulfil the properties of the fuzzy solution. The capability of RK65 is outlined by fathoming to begin with arrange nonlinear FIVP taken after by usage of the convergence theory. Thus, the strategy can be executed and utilized to allow a numerical solution of nonlinear FIVPs.
