Abstract:
This paper introduced type-2 fuzzy non-uniform rational B-spline curve (F2NURBS) interpolation model for type-2 fuzzy data points. The curve model is defined using type-2 fuzzy control points, crisp knot and weight. Later, the data points of type-2 fuzzy NURBS curve after type-reduction and defuzzification is discussed. Finally, a numerical example and an algorithm to generate the model are shown at the end of this paper.
