CHOOSING BEEF FEED SUPPLIERS: A MULTICRITERIA APPROACH THROUGH THE PROMETHEE-ROC METHOD

Livestock, for Brazil, represents great economic importance, as it moves billions of reais annually. To remain competitive in the market, which is subject to several environmental, political and economic factors, numerous cattle breeders seek to increase their production efficiency through investments in the quality of cattle feed, so that they gain weight quickly and in a healthy way. In this sense, it is proposed to build a multicriteria decision model, using the PROMETHEE ROC method, to evaluate six cattle feed suppliers, based on the criteria: "Cost", "Delivery time", "Level of service" and "Time to slaughter". As a result, a ranking of the alternatives was obtained, which was submitted to a sensitivity analysis, in which it was observed that Supplier 1 remains in the first place in 50.1% of the 1 million cases, demonstrating that the alternative, even in the face of variations in the input data, is the most recommended for adherence.
