a useful method for solving fuzzy abc fractional differential equations system

In this paper; a fuzzy mathematical model is considered which is a system ofnonlinear fuzzy atangana–baleanu-caputo (abc) fractional differential equations with fuzzy initial value.first the existence and uniqueness of the solution is determined using generalized hukuhara difference and abc fractional derivative. also, by using r-cuts and by applying numerical abc-pi method, the fuzzy solution of the system of fuzzy atangana–baleanu-caputo (abc) fractional differential equations is calculated.
