The role of the agribusiness has been extremely important in the context of the Brazilian production in terms of both economic values and employment generation. However, the agribusiness specific characteristics have not been sufficiently considered in the literature and even in the development of Production Planning and Control Systems. This thesis is an attempt to fulfill this lack. Two basic aspects were taken into consideration. First, the thesis provides a classification system that allows for identifying those enterprises according to their special characteristics. Second, the architecture of a Planning and Control System is proposed in order to address the main needs of agri-industries, which are dedicated to the raw material splitting up, such as slaughterhouses and mills. In that architecture, it is particularly taken into account demand forecasting and raw material availability restriction. Also, a rule of master production scheduling have been built taking into consideration the simultaneous generation of co-products, which can or not to be immediately needed.
