Environmental criteria in pig diet formulation with Multi-objective Fractional Programming

Abstract

The objective of this chapter is to show how the techniques of Multi-objective Fractional Programming (MFP) can enhance the process of animal diet form- ulation. We propose a model with three objectives and explain how animal diet formulation can be tackled using the method of Interactive Multiple Goal Programming (IMGP). This method allows us to treat the presence of fractional objectives, simplifying the problem from a computational point of view.
