In this paper, we concentrate on the global behavior of the fuzzy difference equations system with higher order αn+1 = τ1 + αn ∑m i=1 βn−i , βn+1 = τ2 + βn ∑m i=1 αn−i , n ∈ N0, where αn, βn are positive fuzzy number sequences, parameters τ1, τ2 and the initial values α−i, β−i, i ∈ {0, 1, . . . , m}, are positive fuzzy numbers. Firstly, we show the existence and unique- ness of the positive fuzzy solution to the mentioned system. Furthermore, we are searching for the boundedness, persistence and convergence of the positive solution to the given system. Finally, we give some numerical examples to show the efficiency of our results.
