Aplicação da lógica Fuzzy na emissão de notas fiscais em processos administrativos na Indústria Lean Office 4.0. Revista de Gestão e Secretariado – GeSec, São José dos Pinhais, PR, v. 16, n. 2, p. 01-13, 2025. DOI: 10.7769/gesec.v16i2.4544.https://rigalileo.itegam.org.br/handle/123456789/379Industry 4.0 has brought the need to integrate advanced technologies to improve the efficiency and agility of administrative processes. This study proposes the application of fuzzy logic to optimize the issuance of invoices, a critical process that faces challenges such as manual errors, delays, and high costs. A fuzzy model was developed that identifies key variables, applies inference rules, and tests the solution in a real environment with operational data. The results indicate a significant reduction in errors and processing times, in addition to gains in tax compliance and customer satisfaction.pdf.Lógica FuzzyEmissão de Notas FiscaisLean OfficeIndústria 4.0Eficiência OperacionalArtigo científicoEngenharia de Produção
