Piecewise Approximation Solution for Nth-order FuzzyDifferential Equations

In this paper a numerical method for solving nth-order fuzzy differential equations is considered. This method which called piecewise approximation method, is obtained by interpolating a polynomial on fuzzy determined values. The proposed method is compared to Allahviranloo's method , and it is shown that this method in more accurate than Al- lahviranloo's method. The piecewise approximation method is illustrated by a comparative example
