The purpose of this paper is to investigate the method of determining experts' weights based on social network analysis (SNA) and to propose a novel fuzzy DEMATEL method based on α- level sets to identify critical factors in supplier evaluation. First, we employ hesitant fuzzy linguistic preference relationships (HFLPRs) to accurately express experts' preferences among evaluation attributes. Subsequently, using SNA, we specify the centrality index of the experts to calculate the expert dependency, which in turn yields the weights of each expert. Next, using the α-level sets, we transform the triangular fuzzy numbers (TFNs) into confidence intervals and constructed three correlation preference matrices via probability density function to maximize the preservation of the original information. Subsequently, we process these three preference matrices by applying the DEMATEL method to identify the key factors under different conditions. Finally, we demonstrate in detail the feasibility and superiority of the proposed method in this paper through case studies and comparative studies.

In Large-Scale Group Decision-Making (LSGDM), effectively implementing consensus models is pivotal for managing decision complexity. While trust-based LSGDM has garnered attention, there remains a need for deeper insights into the dynamics of interexpert trust and the impact of authority effects on the decision-making process. This study introduces a sophisticated model for large-scale group decision-making, incorporating considerations of expert “trustworthiness-authority.” Initially, the study assesses the trustworthiness of experts based on social network relationships and opinion similarity while using background information and consensus levels to establish their authority. Subsequently, experts are categorized into four distinct regions based on their trustworthiness and authority assessments. Furthermore, tailored consensus adjustment methods are proposed for each region based on social contagion theory to facilitate consensus achievement. Additionally, a case study is conducted to demonstrate the rationality and effectiveness of the proposed LSGDM model, considering expert “trustworthiness-authority.” Finally, the necessity and superiority of the proposed model are further verified through comparison analysis and sensitivity analysis.
