Measuring agreement among participants in group decision-making problems is critical to such processes. This paper introduces a novel consensus index derived from the Gini coefficient, which avoids need for traditional aggregation matrices, simplifying calculations while maintaining robustness. The proposed Consensus Index demonstrates properties of reciprocity and boundedness, making it reliable alternative distance-based measures. Through comparative statistical analysis using Wilcoxon...
The mean absolute deviation and the standard deviation, two statistical measures commonly used in quantifying variability, may become an interesting tool when defining consensus measures. Two indexes which obtain level of some problems Group Decision Making are introduced this paper by expanding aforementioned concepts. A comparative analysis reveals that levels derived from these close to those obtained employing distance functions a fuzzy preference relations frame is considered, so they...
