On the O(n3) algorithm for checking the strong robustness of interval fuzzy matrices

Strongly robust interval matrices over (max,min)-algebra (fuzzy matrices) are studied and strong robustness properties are proved, similar to those of classical fuzzy matrices. It is shown that a strong robustness of an interval fuzzy matrix is well-defined using the definition of classical strong robustness. Characterization of strong robustness of interval fuzzy matrices is presented and an O(n3) algorithm for checking the strong robustness of interval fuzzy matrices is described.
