چکیده    Integro-differential equations play a fundamental role in various elds of applied mathematics. the solutions of many engineering problems in general and mechanics and physics in particular, lead to this kind of equations. this paper focuses on the fuzzy volterra integro-diff erential equation of n-th order of the second-kind with nonlinear fuzzy kernel and initial values. this equation is transformed to a nonlinear fuzzy volterra integral equation in multi-integrals by application of a certain analytic solution adapted on fuzzy n-th order derivation under generalized hakuhara derivative. the derived integral equations are solvable, the solutions of which are unique under certain conditions. the existence and uniqueness of the solutions are investigated in a theorem and an upper boundary is found for solutions. an easily-followed algorithm is provided to illustrate the process. the application of the proposed method helps solving the equation on the basis of the adomian decomposition method under generalized h-derivation. comparison of the exact and approximated solutions shows the least error.
