Perturbation techniques for fuzzy matrix equations
Let \(X{\circ}A = B\) be a solvable fuzzy matrix equation, where \(A\) is an \(m{\times}n\) matrix, \(X\) is an \(1{\times}m\) matrix and \(B\) is a \(1{\times}n\) matrix, and \(\circ\) is max-min composition. The author considers the perturbation of some elements of the matrix \(A\) and investigates some problems arising in this situation. Moreover he formulates some open problems in the framework of his considerations.
