摘要：There is no official method to establish a final ranking for the O lympic Games. The usual ranking is based on the Lexicographic Multicriteria Method with its main drawback that is to overvalue the gold medal. Besides, it ignores the results of the winter games. Thispaper proposes a method based on Data Envelopment Analysis (DEA), where the outputs are the number of three type medals that each country won in the Salt Lake City and Sydney games; a constant input is considered for all countries. Restrictions based on the importance of each medal are imposed in the model as the DEA method has an excessive degree of freedom for the w eight assignment for each variable. In order to avoid different weights for each country, a weight average for each input is evaluated and isused, as the coefficient in the weighted sum that establishes the final ranking
