Increasingly, the competition of companies for a better and larger market has generated different ways and strategies to reduce costs in manufacturing and management processes, resulting in lower prices for their products. One of the methodologies used to achieve all this is production planning and control, which helps to identify factors such as: future demand, optimal inventory level, and production requirements needed to manufacture final products. In order to put into practice the knowledge learned in the classroom, a case study was carried out in which the concepts of quantitative forecasting, P and Q inventory models, strategic planning, MRP and priority rules for job arrivals in floor control were implemented.
