Olympic Sports Selection Model Based on Multi-Criteria Decision Making

This paper develops a comprehensive mathematical model for evaluating sports at the Brisbane 2032 Olympic Games by combining six key factors that meet the IOC criteria. The model is a three-dimensional ‘Classification - Entropy Weighting TOPSIS’ framework, which evaluates each unique or non-specialized sport by determining the target weights from the three dimensions of popularity, environmental impact, and fairness through the entropy weighting method, followed by the TOPSIS method of composite ranking. The model was also tested on historical Olympic data, analyzing recently added/removed sports (2020-2028) and traditional core sports (in existence since 1988). The model can successfully explain the continued creation of new sports. Based on the model analysis, we predict that Rugby Union and Roker could be added to the Brisbane Olympics in 2032 and that eSports and Paragliding could be included in the Olympic program after 2036. The model balances traditional Olympic sports and modern sporting trends well and can guide Olympic program decisions.
