A New Approach for Solving Forth Order Fuzzy Differential Equations Under Generalized Differentiability

In this paper a numerical method for solving forth order fuzzy differential equations under generalized differentiability is proposed. This method is based on the interpolating a solution of forth order fuzzy differential equation by piecewise polynomial of degree 8 in the range of solution. We investigate the existence and uniqueness of solutions. Finally a numerical example is presented to illustrate the accuracy of the new technique.
