Abstract(s)
A competitividade do mercado impulsiona a indústria de fabricação de motores elétricos a
otimizar os seus processos, incluindo a embalagem dos produtos, dado o atual cenário
globalizado. Grandes indústrias tendem a internalizar processos para agregar valor ao longo da
cadeia de produção e reduzir a dependência de fornecedores. Avaliar essas alternativas de
internalização é crucial para uma tomada de decisão informada, sendo fundamental
compreender as diversas perspectivas, lacunas de informação e vieses que podem influenciar
uma decisão de forma inadequada. Um modelo de Apoio Multicritério à Decisão (AMD) foi
desenvolvido usando o método SAPEVO-M, que implementa uma metodologia AMD para
grupos. Este método permite a definição lógica e estruturada de alternativas e critérios, assim
como a agregação das valorações de cada alternativa em cada critério, resultando na seleção e
ordenação das mesmas. Foram utilizados sete critérios e quatro alternativas para a avaliação
das alternativas. Adicionalmente, uma análise de sensibilidade foi conduzida para compreender
a robustez da decisão e avaliar o comportamento das alternativas diante de diferentes
variações nas ponderações dos critérios. Por fim, é possível definir a melhor alternativa
plausível no contexto em que a empresa está inserida, guiada por critérios lógicos e definidos.
Através de uma abordagem axiomática, este modelo permite a ponderação das opiniões de
múltiplos decisores, compreendendo suas preferências e estabelecendo um ranking entre as
alternativas face aos critérios definidos como relevantes, possibilitando uma avaliação
abrangente, com dados qualitativos, levando em consideração a subjetividade inerente à
decisão.
Market competitiveness is driving the electric motor manufacturing industry to optimize its processes, including product packaging, in the current globalized scenario. Large industries tend to internalize processes to add value along the production chain and reduce dependence on suppliers. Evaluating these internalization scenarios is critical for informed decision making, and it is essential to understand the different perspectives, information gaps, and biases that can unduly influence a decision. A multicriteria decision support (AMD) model was developed using the SAPEVO-M method, which implements an AMD methodology for groups. This method allows the logical and structured definition of alternatives and criteria, as well as the aggregation of the scores of each alternative in each criterion, resulting in their selection and ranking. Seven criteria and four alternatives were used to evaluate the scenarios. In addition, a sensitivity analysis was performed to understand the robustness of the decision and to assess the behavior of the alternatives in the face of different variations in the weighting of the criteria. Finally, it is possible to define the best plausible alternative in the context of the company, guided by logical and defined criteria. Through an axiomatic approach, this model makes it possible to weight the opinions of several decision makers, to understand their preferences and to establish a ranking between the alternatives in relation to the criteria defined as relevant, allowing a comprehensive evaluation with qualitative data, taking into account the subjectivity inherent in the decision.
