This work presents optimization models to support decisions of the Production Planning and Control (PPC) in the industry of grains electrocasting. A case study was accomplished in one of the largest companies in the State of São Paulo. The objective of the study is to contribute for the improvement of the system of PCP of companies of grains electrocasting, in such a way to obtain gains of productivity and to improve the user service level with respect to due date satisfaction. For that Mixed Integer Linear Programming models were applied to aid particularly in the decisions of production scheduling. Optimizing the production scheduling in the industry of grains electrocasting is not a simple task, mainly due to the greatness of setup times of the equipments, the diversity of products and the limitations of the order due dates.
