Aggregation and Ranking on an Ordinal Scale Using Threshold Evidential Combination Rules
A new method of aggregation and ranking on an ordinal scale is proposed based on the method of evidential ranking previously developed by the author, but using the tools of threshold aggregation of bodies of evidence. This method has better robustness and stability compared to the threshold-free method. The method allows you to take into account focal elements that are significant and insignificant for aggregation with different weights, which improves its sensitivity. The application of the developed method to aggregating information from reviewers and ranking reports/articles in a conference management system such as EasyChair is considered. This method can be used to rank alternatives presented as a set of bodies of evidence obtained from different sources of information.
