In this paper, we generalize our previous results regarding approximate solutions of fuzzy relation equations to systems of fuzzy relation equations. By employing the equality index proposed by Gottwald, we introduce a goodness measure of the performance of approximate solutions and derive a lower bound and an upper bound of solvability of s stems of fuzzy relation equations. We also show that our results generalize those presented for one-dimensional fuzzy relation equations in [2].
