This paper proposes a novel multi-objective model to support the distribution of retailers' funds among farms by considering the vegetables' perishability and the dependence of prices on the vegetables' freshness, being a novelty of the proposal. The multi-objective model simultaneously optimizes five objectives: maximization of SC profits, minimization of generated waste, minimization of the economic unfairness among farmers, minimization of the unfairness in the distribution of funds, and the maximization of the freshness of vegetables at their sale moment. This last objective as well as the joint optimization of the five objectives are novelties of this proposal. The multi-objective model is solved by using the ε-constraint method being the non-linear objectives linearized. Results show that interesting trade-offs can be found among objectives, with solutions that decrease the unfairness perception and increase the freshness of sold vegetables at the expense of a small reduction in profits
