Research on evaluation of manufacturing cloud service oriented to environmental benefits of supply chain

From the perspective of improving the environmental benefits of the supply chain, in this paper, the evaluation index system of manufacturing cloud service is established. It is oriented to the environmental benefits of the supply chain and takes into account the environmental indicators of the candidate providers. The fuzzy DEMATEL modified entropy method is used to calculate the comprehensive weight of the evaluation index. Then, the candidate manufacturing cloud service providers are selected based on gray relational analysis to ensure the rationality of the evaluation results. The evaluation system not only objectively considers the situation of each supplier but also reflects the platform's emphasis on low-carbon environmental factors. Finally, this paper takes the seat suppliers' selection problem in the supply chain of Tianjin industrial cloud automotive mold supply chain as examples to verify the practical significance of this model. At the same time, this paper can provide ideas for the application of cloud manufacturing mode and the solution of supply chain environment problems.
