Abstract(s)
Escolher o fornecedor certo ou errado tem um impacto significativo nas operações de uma empresa, torna-se assim fundamental avaliar o desempenho de fornecedores para uma gestão eficaz da cadeia de abastecimento, especialmente na indústria aeronáutica, onde os fatores de qualidade, a fiabilidade e o cumprimento de normas rigorosas são essenciais para garantir a segurança da operação. No presente documento é proposto um modelo de avaliação de fornecedores adaptado ao setor aeronáutico, baseado na lógica difusa de modo a abordar a complexidade e incerteza no momento da avaliação do desempenho dos fornecedores. O modelo proposto integra critérios qualitativos, como a fiabilidade de entrega, compromisso com a qualidade, relação com fornecedores e custo, ponderados conforme a sua importância estratégica. Com a aplicação do modelo numa empresa do setor foi possível validar a sua aplicabilidade. Os resultados mostram que a lógica difusa proporciona uma avaliação mais aprofundada das capacidades dos fornecedores e facilita decisões mais informadas. A adaptabilidade do modelo permite ajustar os critérios e os seus pesos na avaliação conforme as mudanças do mercado e as prioridades estratégicas. O modelo desenvolvido permite selecionar e gerir fornecedores de forma mais eficaz, contribuindo para um melhor desempenho da cadeia de abastecimento.
Abstract Supplier evaluation is fundamental in effective supply chain management, especially in the aerospace industry where quality, reliability and compliance with stringent regulatory standards are essential. This document proposes a supplier evaluation model adapted for the aerospace sector, based on fuzzy logic in order to address the complexity and uncertainty when assessing supplier performance. The proposed model integrates qualitative criteria, including delivery performance, quality compliance, supplier relationships and cost, weighted according to their strategic importance. Fuzzy logic allows the incorporation of subjective judgments and linguistic variables into the evaluation process, allowing a more comprehensive and flexible analysis. By applying the model to a company in the sector, it was possible to validate the applicability and effectiveness of the model applicability and effectiveness. The results demonstrated that the fuzzy logic-based model offers significant advantages over traditional evaluation methods, providing deeper insights into supplier capabilities and facilitating more informed decision-making. The model's adaptability also allows evaluation criteria and weightings adjustments according to changes in the market conditions and strategic priorities. The model developed improves the ability of aeronautical companies to select and manage suppliers more effectively, contributing to better supply chain performance. Future research could explore the inclusion of criteria such as risk management and environmental sustainability to further refine the model.
