Performance assessment of the soccer teams in Brazil using DEA

Abstract

In this paper we propose a DEA (Data Envelopment Analysis) based ranking for Brazilian soccer teams. Ranking is a major issue for the soccer clubs, either when looking for sponsorship or expanding their supportive group. We first include value judgements, applying a method to consolidate the results of the national and international matches. Then we use both aggregate results as outputs for applying the DEA model. Rankings published by the Brazilian Soccer Confederation (CBF) and 'Placar', a traditional sports magazine, do not give any credit to international titles and national cups, focusing only on the results in the National League. We compare the DEA ranking with the Federation's and the magazine's, raising some controversial issues and drawing unexpected conclusions.Keywords: soccer in Brazil; data envelopment analysis; decision aid. ResumoNeste artigo é proposto um ranking baseado em Análise Envoltória de Dados (DEA) para os times de futebol brasileiros. Ranking é uma questão importante para os clubes, quer seja quando procuram patrocínio ou expansão da torcida. Primeiramente incluídos julgamentos de valor, utilizando um método para consolidar resultados de torneios nacionais e internacionais. Em seguida usamos ambos agregados como outputs para a aplicação do modelo DEA. Os rankings da Confederação Brasileira de Futebol (CBF) e da tradicional revista Placar, por exemplo, não dão nenhum crédito a títulos internacionais e nacionais, focalizando apenas no resultado da Liga Nacional. O ranking obtido via DEA é comparado com os da CBF e da revista, o que ocasiona certa controvérsia e conclusões inesperadas.Palavras-chave: futebol no Brasil; análise envoltória de dados; apoio à decisão.
