PROTEIN SUPPLEMENT PRIORITIZATION FOR NATURAL PRODUCTS STORE ACQUIRE: A MULTICRITERIA APPROACH THROUGH THE FITRADEOFF METHOD

Considering the importance of a balanced diet, the central role of proteins stands out, as they are essential for functions such as muscle regeneration and metabolic support. Although found in foods like meat, eggs, and legumes, many consumers opt for protein supplements, mainly due to their convenience. In this context, this study proposes a multi-criteria decision support model to assist a store in prioritizing which supplements to acquire. The model, developed with the support of a nutritionist and using the method FITradeoff for ranking, also incorporated stakeholder input, as many customers were requesting lactose-free options due to their intolerance. After 12 cycles, a complete pre-order was obtained. Furthermore, through the application of sensitivity analysis using data variation, the robustness of the solution was confirmed. Thus, the model helps structure the decision-making process, supporting the selection of supplements and serving as a management tool for the store.
