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 ( n 3 ) algorithm for checking the strong robustness of interval fuzzy matrices is described.
