Abstract: This paper studies the first order fuzzy differential equations with initial value problem by using the strongly generalized differentiability concept. Utilizing the predictor-corrector method, the problem of finding a numerical approximation of solutions is investigated. The method’s applicability is illustrated by solving a linear first-order fuzzy differential equation.
