Uso da Lógica Fuzzy na avaliação da viabilidade do ciclo de vida do biodiesel

Abstract: A Avaliação do Ciclo de Vida (ACV) é uma ferramenta promissora para pôr em pratica o Pensamento do Ciclo de Vida. Contudo, apresenta algumas limitações como a alocação de impactos entre produtos e coprodutos, a expansão de fronteiras, categorias de impacto relevantes regionalmente, disponibilização de inventários, subjetividade das escolhas e avaliação integrada da sustentabilidade. Nesse contexto, a Lógica Fuzzy, associada à análise multicriterial, vem sendo apontada como um método com potencial para … Show more

“…The Fuzzy Logic was applied through a Multicriteria Fuzzy Controller (MFC), composed of a Fuzzi er, Fuzzy Inference System (FIS), and Defuzzi er modules. The MFC was based on the multicriteria controller proposed by Maranduba et al (2017), adding adaptations necessary to make the controller able to evaluate future input values.…”

“…So, the synergy between cLCA and Fuzzy Logic comes up with the great potential to build a scienti cally robust and reliable tool for decision-makers from the public or private sector to decide about a product, technology, or scenario considering the degree of relevance on a sustainability scale predetermined to each study case (Maranduba et al 2017).…”

“…Khatchatourian & Treter (2010) developed a methodology based on fuzzy logic for evaluation and classification of economic and financial performance of agricultural cooperatives. Maranduba et al (2016) used fuzzy logic to evaluate the viability of the life cycle of biodiesel produced in Brazil, considering two mixing scenarios: B7 (7% Biodiesel and 93% fossil diesel) and B10 (10% biodiesel and 90% of fossil diesel). Cardoso et al (2018), through Fuzzy logic, was able to characterize and successfully map the uncertainties of both rainfall and erosivity to the state of Bahia, Brazil.…”

“…Maranduba et al (2017), adding adaptations necessary to make the controller able to evaluate future input values.Due to the exponential ratio between the fuzzy controller and the universe of rules, and the rules directly affects the computational processing time, the Fuzzi er considered only three inputs (fuzzi cation): Climate Change -CC, as an environmental requirement from the COP-21 agreement, and generated by the cLCA; Cumulative Exergy Demand -CExD, as a relevant technical requirement for fuel viability, and caused too by the cLCA; and, Price at the Supplier -Price, indicators from the economic dimension. So, the MFC proposed and modeled considered three dimensions relevant to fuel sustainability/viability: environmental, technical (exergetic), and economical.…”
