The study starts with a analysis of ERP systems, how they were introduced and evolved over time in enterprises. Risks and benefits of ERP systems are analyzed as well as the issues that arise during and after their implementation. The significance of ERP systems in the food manufacturing industry is thorougly presented, focusing on the specific requirements from an ERP system that should be taken into account in the agricultural industry. ERP systems designed exclusively or extensively used in the food/agricultural industry are also presented. Furthermore, there is a detailed study of SAP MII system, a software designed to operate in the manufacturing industry connecting with its features and functionalities the ERP and manufacturing layers in an enterprise. As a next step, the focus is placed on the significance of forecasting methods used in the food manufacturing in terms of product, raw materials etc. These methods are then integrated in the architectural layer connecting ERP systems and real time manufacturing systems and controls. Finally, some indicative scenarios introduced in order to analyze the methodology of the interconnection of ERP and real time manufacturing systems. The results and conclusions demonstrate the importance of such an implementation especially in the cases of products with short lifecycle such as fresh vegetables, agricultural products and food products in general.
