“…Multi-attribute group decision-making (MCGDM) refers to the preferred decisionmaking processes of multiple DMs' in selection, ranking, and evaluating based on multiple unrelated attributes. However, because of the complexity of the decision-making environment and the ambiguity and uncertainty of DMs' preference information, tradition fuzzy sets (FSs) [6,7] and their extensions, including spherical fuzzy sets [8,9], complemental fuzzy sets [10], Z-numbers [11][12][13], intuitionistic fuzzy sets (IFSs) [14][15][16][17][18][19][20], hesitant fuzzy sets (HFSs) [21][22][23][24][25][26], Pythagorean fuzzy sets [27,28], disc Pythagorean fuzzy sets [29], Fermatean fuzzy sets [30][31][32][33], interval-values fuzzy sets [34,35], and q-rung orthopair fuzzy sets [36,37], have been applied to solve MCGDM problems.…”

In order to further investigate the level of online medical services in China and improve the medical experience of patients, this study aims to establish an online review-driven picture fuzzy multi-criteria group decision-making (MCGDM) approach for the online medical service evaluation of doctors. First, based on the Aczel–Alsina t-norm and t-conorm, the normal picture fuzzy Aczel–Alsina operations involving a variable parameter are defined to make the corresponding operations more flexible than other operations. Second, two picture fuzzy Aczel–Alsina aggregation operators are developed, and the corresponding properties are discussed as well. Third, combined with the online review information of China’s medical platform Haodaifu, the online review-driven evaluation attributes and their corresponding weights are obtained, which can make the evaluation model more objective. Fourth, an extended normal picture fuzzy complex proportional assessment (COPRAS) decision-making method for the service quality evaluation of online medical services is proposed. Finally, an empirical example is presented to verify the feasibility and validity of the proposed method. A sensitivity analysis and a comparison analysis are also conducted to demonstrate the effectiveness and flexibility of the proposed approach.
