Abstract :

In 2014, Gong et al. proposed a simple method for solving dual fuzzy matrix equations in $LR$ form. Later, Kaur and Kumar showed that there is a technical flaw in their method and it is valid only for certain types of $LR$ dual fuzzy matrix equations. The main aim of this paper is to eliminate this technical flaw and also correct some numerical results obtained by Gong et al..
