Solutions of Fuzzy Time Fractional Heat Equation

Fuzzy fractional heat equations (FFHEs) are utilized to an- alyze the behaviour of the certain phenomena in various mathematical and scientic models. The main goal of this paper is to construct the solution of fuzzy fractional heat equations by taking a reliable recipe of Sumudu transformation method and homotopy analysis method into account. These method allow us to remove the diculties and restric- tions confronted in other methods. The feasibility of this method is conrmed by given numerical examples. The result presented that the proposed method is suitable, powerful and reliable for obtaining the solution of fuzzy fractional problems with FFHEs.
