Abstract
With the continuous development of big data techniques, more and more group decision-making problems involve multiple decision-makers. In the era of big data, massive data can improve decision-making ability and provide good support for decision-making. Large-Scale Group Decision Making (LSGDM) has been developed, and it discusses many cases where decision-makers are related to the decision-making process. However, the current LSGDM model has some shortcomings. To end this issue, this paper proposed a novel LSGDM method to study the role of the big data-driven decision-making issue. In this regard, existing literature and expert interviews were used to collect research standards. Then, a fuzzy LSGDM judgement matrix decision-making method based on group analysis is proposed. Finally, the method is applied to evaluate the takeout service platform. The results show that seven respondents need to adjust the acceptable consistency of the fuzzy judgement matrix, and they can quickly reach a satisfactory consensus. The results can further enrich and improve the group decision-making method based on a fuzzy judgement matrix.
