Fuzzy symmetric solutions of fuzzy matrix equations

Abstract

The fuzzy symmetric solution of fuzzy matrix equation A X = B , in which A is a crisp m m nonsingular matrix and B is an m n fuzzy numbers matrix with nonzero spreads, is investigated. The fuzzy matrix equation is converted to a fuzzy system of linear equations according to the Kronecker product of matrices. From solving the fuzzy linear system, three types of fuzzy symmetric solutions of the fuzzy matrix equation are derived. Finally, two examples are given to illustrate the proposed method.
