Advantage of gH-difference on the second-order fuzzy linear differential equations with constant coefficients

In this article by using the concept of generalized Hukuhara difference, the second-order fuzzy differential equation problem with constant coefficients is solved. Then the solution will be compared with each other in two cases. The first case is, when displacement is not performed. It means: the right side of second-order fuzzy differential equation is not transferred to the left side. The second case is when displacement is performed by applying generalized Hukuhara difference concept. We show that forcing term under gH-difference dose no exist when displacement is not performed, the solutions of bout fuzzy differential equations are the same by considering gH-difference.
