Abstract.In this paper a particular numerical algorithm of P(EC)$^N$E-modes for solving initial value problem (IVP) of $k$-th order fuzzy differential equations (FDE) is presented. First of all we will transform an IVP of $k$-th order fuzzy differential equation to an IVP of the system of first order fuzzy differential equations, then we solve this system, numerically. After that we obtain the approximate solution of the $k$-th order FDE. Also we will prove that the algorithm converges to the exact solution as the stepsize goes to zero, and at the end the validity of the algorithm is illustrated by solving some examples.
