Abstract : « A global approach to solve pooling problem applied to feed mix industry » deals with the resolution of non linear non convex optimization problem which can occur in the feed mix industry. Feed mix industry problems are close to pooling problem, well-known in the literature. They are aimed to help decision maker in formulating feed, ie. To decide how to blend raw material to make a product satisfying nutrient and production constraints. The brand-and-bound algorithm presented in this these is aimed to solved large-scaled bilinear problems with bilinear constraints. A lagrangian approach has also been developed to obtain valid lower bound.
