Matrices approchées de systèmes d’équations relationnelles floues de type max-min

max-min fuzzy relational equations (S) : A?max min x = b by minimally modifying the matrix A that governs the system (S). Our method generates consistent systems of the form A??max min x = b that are close to the inconsistent system (S) in the following sense : the right-hand side vector of each consistent system is the right-hand side vector b of the system (S) and the coefficients of the matrix A? are obtained by minimally modifying some coefficients of the matrix A of the system (S) that must be corrected to achieve consistency. We show how to obtain consistent systems that minimize the distance ?A? ?A?p where p ? {1, 2,?}.
