SUMMARY:

The brewing sector, due to the increase in production activity and the more demanding taste of the consumer, has sought to improve the quality of the beer produced, having even used artificial intelligence methodologies to deal with the uncertainty, subjectivity and complexity associated with this type of bioprocess engineering problem. The Fuzzy system is one of those methodologies that, in addition to generality, expressive power and the ability to model real-world problems, act to circumvent the imprecision implicit in decision-making problems. Thus, this research aimed to develop two decision support systems through a Fuzzy system. The first Fuzzy system was developed to evaluate the quality of Pilsen beer, and the second Fuzzy system aimed to identify different types of beer. The methodology involved collecting user information about the following types of beer: Pilsen, Wheat, Stout and IPA. The system was developed using Scilab® and INFUZZY Software and the input variables for the first decision support system were CO2, color, density, pH and alcohol content, and the response variable was beer quality. . The developed system had a hit rate above 90% for beer approved for consumption and 85% for beer that was not approved. In addition, considering simulated scenarios, the second Fuzzy system correctly predicted, more than 99% of the time, the alcohol content, color and density of the beer produced, indicating to the user the type of beer chosen.
