“…In 2008, T.Allahviranloo et al [22] solved Nth-order fuzzy linear differential equations.The fuzzy Laplace transforms for solving first order fuzzy differential equations under H-differentiability have proposed by Allahviranloo and Ahmadi [2].A new method for solving fuzzy linear differential equations obtained by T. Allahviranloo, S.Abbasbandy, and S. Salahshour , A.Hakimzadeh [21]. The fuzzy Laplace transforms to solve second-order FIVPs under generalized H-differentiability applied by S.Salahshour, T.Allahviranloo [3].The fuzzy approximate solutions of second order fuzzy linear boundary value problems found by Xiaobin Guo,Dequan Shang and Xiaoquan. [25] Strongly generalized differentiability was introduced and studied by Bede et al [5,6] the existence and uniqueness theorem of solution of Nth-order fuzzy differential equations under generalized differentiability was studied by S Salahshour [18].In 2015,Patel and Desai [15] find solution of variable coefficient fuzzy initial value problems by properties of Linear Transformtion.The strongly generalized derivative is defined for a larger class of fuzzy valued function than the H-derivative, and fuzzy differential equations can have solutions which have a decreasing length of their support.…”
