چکیده
Throughout this article, our main idea is to analyze from a theoretical and normative point of view different methods aggregate individual rankings. To do so, first, we introduce the concept general mean on an abstract set. This new conciliates social choice—where well-known impossibility results as Arrovian ones are encountered—and decision-making approaches—where necessity fusing rankings unavoidable. Moreover, it gives rise reasonable definition ranking fusion function that does indeed satisfy axioms mean. Then, will some build functions, paying special attention use score pointing out equivalence between scoring. conclude, prove any introduces partial order implemented finite set alternatives. Therefore, allows us compare aggregation, so in practice, one should look for maximal elements with respect such orders defined

We scrutinize and compare, from the perspective of modern theory of social choice, two rules that have been used to rank competitors in Figure Skating for the past decades.

The four rules are illustrated with examples and with the ...
