The presentation addresses the problem of sorting objects based on
incomplete pairwise comparison matrices. An example of using interval-
valued fuzzy logic is the ranking of the best female tennis players
according to the win/loss ratios. An incomplete pairwise comparison
matrix (PCM) is constructed using information obtained from the official
website of the Women's Tennis Association (WTA). The top 29 players on
the official WTA rankings have their live results from 1973 to 2024
included in the database. Using Bayesian statistics, an incomplete
interval-valued fuzzy preference relation is derived from the incomplete
PCM, and various optimization models are used to determine the
consistent interval-valued weight vectors.
