Avaliação da sustentabilidade das cadeias de suprimento usando a escala likert e a lógica fuzzy

Abstract

This work evaluates the Sustainability Index of supply chains, considering practices and organizational performance. To this end, the four component parts of the supply chains were identified in order to evaluate the Sustainability Index of each component part, as well as the Chain as a whole. The Likert Scale and the Fuzzy Logic were used in the evaluation context. The model was applied to a case study in a company in the city of Manaus. The results obtained were acceptable in relation to the reality of the company "ALFA", as well as recommendations were suggested to improve the company's Sustainability Index. The results obtained by the Excel tab and fuzzy logic were compared. The Chain Sustainability Index according to the Fuzzy System was 53.5, reaffirming that the Excel tab was 55.53, giving a difference of only 3.5%, demonstrating the validity of both systems developed to determine the Sustainability Index of the supply chain. Thus, both procedures analyzed allowed us to effectively calculate the Supply Chain Sustainability Index of any one company.
