Multi-objective Programming model to design a sustainable Food Supply Chain Considering Dietary Factors

FOOD is an essential component of today's life but the environment and the food secutrity can be under threat by current consumption and production patterns. Therefore, dietary choices need to be reconsider. This paper addresses a novel application of a network design problem by considering sustainability issues. For this purpose, a multi-objective linear programming model proposed in order to design a food system with a sufficient dietary intake level. The first objective function aims to minimize total costs, the second objective function minimizes environmental impacts and the third one optimizes social impacts. Then, the proposed multi-objective is converted to a single-objective model by using LP-metric method and solved by LINGO software. Finally, a sensitivity analysis is done in some parameters of the proposed model and results are reported.
