Article analysis:

The article “Large-Scale Group Decision Making: A Systematic Review and a Critical Analysis” provides an in-depth review of the literature on large-scale group decision making (LSGDM). The authors have conducted a thorough search of the Web of Science database to identify relevant studies on LSGDM, resulting in 241 contributions that were then narrowed down to 87 after a selection process based on language, type of contribution, and relevance to the topic. The authors then analyze these 87 contributions from four perspectives – preference structure, group decision rules, techniques for verifying quality, and applications to real world problems – before providing a critical analysis of their limitations and proposing new research lines for LSGDM.

The article is generally reliable in its approach as it provides an extensive overview of existing literature on LSGDM while also critically analyzing its limitations. However, there are some potential biases that should be noted. For example, the authors focus primarily on Western literature when conducting their review; this may lead to an incomplete or one-sided picture as other regions may have different approaches or perspectives that could be valuable in understanding LSGDM more fully. Additionally, while the authors provide a critical analysis of existing proposals’ limitations, they do not explore any counterarguments or alternative solutions that could address these issues; this could lead to an overly negative view of current approaches without considering potential solutions or improvements. Finally, while the authors note that their study was supported by various grants from Spanish and Chinese organizations, they do not discuss any potential conflicts of interest that may arise due to this funding source; this could lead to partiality or bias in their conclusions if such conflicts exist but are not acknowledged or addressed.
