Auxiliary models for Linear Programming problems with fuzzy coefficients in the constraints (Spanish)

This paper considers a Linear Programming problem in which the coefficients in the system of linear inequalities defining the constraint set are given in an imprecise, or vague, way. It is supposed that those coefficients may be defined by means of fuzzy numbers. An approach of solution based upon the several versions that exist to compare fuzzy numbers is proposed. Finally, corresponding to the different ways to compare fuzzy numbers, distinct auxiliary models of Linear Programming are obtained. From each of these a solution to the former problem may be obtained.
