A model for goal programming with Type-2 fuzzy uncertainty

This paper presents a goal programming model for problems where resources are defined by the opinion of multiple experts. Through the use of Type-2 fuzzy sets, we propose a model that includes human being like information in order to define the parameters of a goal programming problem, and then solve it using a constructive approach based on LP models and α-cuts. An application example is provided and explained, and some concluding remarks are provided.
