Abstract(s)
A indústria 4.0 compreende a aplicação de diferentes soluções tecnológicas de modo que os processos de negócios em toda a cadeia produtiva sejam integrados. A realização da seleção de fornecedores considerando os requisitos da indústria 4.0 é essencial na promoção de estratégias colaborativas entre fornecedores e fabricantes. Nesse enquadramento, por meio de uma revisão sistemática, foram caracterizados os estudos que propuseram modelos quantitativos para apoiar a seleção de fornecedores no contexto da indústria 4.0. No entanto, não foram encontrados modelos que empreguem critérios de avaliação de fornecedores relacionados a requisitos advindos da indústria 4.0, e que consideram a dificuldade de coletar dados para medir o desempenho dos fornecedores. Assim sendo, a fim de preencher a lacuna de pesquisa identificada, este estudo propõe um modelo de decisão para apoiar a seleção de critérios e fornecedores, com base na combinação de Hesitant Fuzzy Linguistic Term Set (HFLTS) com o método Quality Function Deployment (QFD) considerando um conjunto de critérios definidos a partir de requisitos advindos da indústria 4.0. Para isso, um modelo computacional foi desenvolvido no MS Excel e aplicado em um caso ilustrativo utilizando dados simulados. Por meio dos resultados da aplicação, é possível constatar a capacidade do método em apoiar a tomada de decisão em grupo e considerar pesos diferentes para os julgamentos dos decisores na escolha dos critérios e na avaliação dos fornecedores. A sensibilidade nos parâmetros de saída do modelo às alterações nos parâmetros de entrada sugere efetividade do modelo proposto.
Industry 4.0 comprises the application of different technological solutions so that business processes throughout the integrated production chain. Carrying out the selection of suppliers considering the requirements of industry 4.0 is essential in the promotion of collaborative collaborators between suppliers and manufacturers. In this context, through a systematic review, studies were characterized that proposed quantitative models to support the selection of suppliers in the context of industry 4.0. However, no models were found that use supplier evaluation criteria related to requirements arising from industry 4.0, and which consider it a difficulty to collect data to assess supplier performance. Therefore, in order to fill an identified research gap, this study proposes a decision model to support a selection of criteria and suppliers, based on the combination of Hesitant Fuzzy Linguistic Term Set (HFLTS) with the Quality Function Deployment (QFD) method considering a set of criteria defined from the requirements arising from industry 4.0. For this, a computational model was developed in MS Excel and applied in an illustrative case using simulated data. Through the results of the application, it is possible to verify the capacity of the method to support group decision making and consider different weights for the judgments of decision makers in the choice of criteria and in the evaluation of suppliers. The sensitivity of the model's output parameters to changes in the input parameters, the effectiveness of the proposed model.
