This research presents the formulation of a mixed integer linear programming model with the aim to optimize the production planning of a pig supply chain. The model maximizes the total revenue of the chain. Income depends on animals sold to the abattoir and main costs summarises feeding, doses of insemination, labour, transportation and veterinary expenses. A time horizon of three years is considered on a weekly basis. Furthermore, the proposed model provides the best production planning, that is, the flow of animals among farms and towards the abattoir, the number of animals to be produced and transferred at each phase and stage. Number of trucks and optimal replacement policy for each sow farm, as well as the optimal delivering of fattened pigs to the abattoir. Finally, It is demonstrated how the optimal solution for the whole supply chain it is different that the optimal solution for individual farms.
