Abstract: This paper proposes a new method to solve nth order fuzzy differential equations using collocation type of method. In the solution procedure Legendre polynomials are used in the collocation method. Three different cases have been considered for the analysis. Known example problems are solved using the proposed procedure. Obtained results are compared with the exact solution in order to illustrate the efficiency and reliability of the proposed method. Solutions are depicted in term of figures and tables.
Keywords: Gaussian fuzzy numbers; Legendre polynomials; nth order; fuzzy differential equations; FDEs; fuzzy logic; orthogonal polynomials; collocation.
