A Multi-objective Approach for Supply Chain Network Design: Tilapia Pisciculture in Paraná State – Brazil

Nowadays, efficient supply chain network design is a major issue, which becomes a greater challenge with the need to consider environmental and social concerns in decisions, besides economic issues. This paper develops a supply chain planning model based on a multi-objective framework that considers economic, social and environmental issues. The model is applied to the tilapia pisciculture supply chain in Brazil. A pay-off matrix is derived and an approximation of the Pareto frontier is built using the augmented ?-constraint method. Several non-dominated solutions are generated and analyzed in order to propose the preferable scenarios of supply chain network design.
