Multi-criteria Group Decision-making Method Based on Expert Trust Network and Cloud Model
Xin Luo, Huajun Zhang · 2021
Aiming at the fuzzy weight of experts, the complexity of objects and the fuzziness of human thinking in the process of multi-criteria group decision-making, this paper proposed to use expert trust network and cloud model operators to realize the comprehensive evaluation decision-making based on linguistic variables. Firstly, the linguistic evaluation information of linguistic term sets are transformed into corresponding numerical information, which are transformed into corresponding cloud models. At the same time, the expert weight is calculated iteratively by using expert trust network. Finally, the comprehensive evaluation index is obtained by the CWAA operator.
