Abstract

An \(n \times n \) interval matrix \({\mathcal {A}}= [\underline{A},\overline{A}]\) is called to be a fuzzy interval matrix if \(0 \le \underline{A}_{ij} \le \overline{A}_{ij}\le 1\) for all \(1 \le i, j \le n\). In this paper, we proposed the notion of max-min algebra of fuzzy interval matrices. We show that the max-min powers of a fuzzy interval matrix either converge or oscillate with a finite period. Conditions for limiting behavior of powers of a fuzzy interval matrix are established. Some properties of fuzzy interval matrices in max-min algebra are derived. Necessary and sufficient conditions for the powers of a fuzzy interval matrices in max-min algebra to be nilpotent are proposed as well.
