Fuzzy minimal solution of positive fully fuzzy matrix equations

In this paper, a class of fully fuzzy matrix equation ̃ÃX = ̃B is investigated. The original fuzzy matrix equation is extended into a crisp system of matrix equations according to the arithmetic operation of LR fuzzy numbers. The fuzzy approximate solutions of the positive FFMEs are obtained by solving the system of matrix equations. An example is given to illustrate the efficiency of the proposed method.
