In this paper, the cubic Bézier curve interpolation method for intuitionistic fuzzy data is introduced based on the theory of intuitionistic fuzzy sets. The intuitionistic fuzzy point relation and intuitionistic fuzzy control point relation is defined based on intuitionistic fuzzy point, intuitionistic fuzzy number and intuitionistic fuzzy relation concepts. Next, the intuitionistic fuzzy control point relation is blended with the Bernstein basis function and the intuitionistic fuzzy cubic Bézier curve is produced. Then, the intuitionistic fuzzy data is interpolated and visualized by using the intuitionistic fuzzy cubic Bézier curve.
