Abstract
In most competitive sports, one of the main interests of the audience is to know who is truly strong. Various tournaments are held to determine the strongest champions, but the winners depend on the tournament regulations to no small degree. It is not always sure that the champion is the highest-performing team/player. The outcome of a competitive sports match, which wins, can be analogous to a pairwise comparison in decision-making. In many competitive professional sports leagues, all teams belonging to a league fight each other in a round-robin tournament, and the team with the most wins is honored as the champion. However, in Japan's professional sumo league, Ozumo, about 40 sumo wrestlers, rikishi, compete in a limited schedule of 15 days, so not all combinations of rikishi compete against each other. Using a method that handles incomplete pairwise comparisons, we propose a method for obtaining the values representing the actual performance of teams/players from the results of a semi-round-robin tournament such as Ozumo. For the construction of a pairwise comparison matrix, we consider match time. We also provide applications to the actual data of Ozumo.
