Resumo: Nowadays, the interest of organizations by professionals who have deep knowledge concerning more than one language has been increasing. In this scenario, the choice of a language school has been one of the most common decision problems, which has been often made on the basis of word-of-mouth, marketing activities of schools and trials without criteria. In order to contribute to this problem, this paper presents a study in which two multi-criteria decision aid methods (AHP and Weighted Average) were used to select a language school. Thus, the degree of importance of criteria relating to the problem and the degree of satisfaction of undergraduate and postgraduate students in relation to language schools they study were taken into account. The best ranked language school was the same for both MCDA methods, although some schools have obtained different positions. It was found that the analysis with AHP is richer and more elaborate than with the Weighted Average method. However, the large number of pairwise comparisons which were required to the study demanded significant attention and cognitive effort from the decision maker, and more time to perform the analysis - aspects that may contribute to the preference for the Weighted Average method in similar studies.

Neste cenário, a escolha de uma escola de idiomas tem sido um dos problemas decisórios mais comuns, muitas vezes realizada em função de informações boca-a-boca, ações de marketing das escolas e experimentações sem critérios. Desejando contribuir para este problema, este artigo apresenta um estudo no qual foram empregados dois métodos de apoio à tomada de decisão (AHP e Média Ponderada) com o objetivo de escolher uma escola de idiomas. Para tanto, foram considerados o grau de importância de critérios relativos ao problema e o grau de satisfação de estudantes de graduação e pós-graduação em relação às escolas de idiomas que frequentavam. A escola de idiomas mais bem ordenada foi a mesma em ambos os métodos de AMD, embora algumas escolas  tenham obtido posições diferentes. Foi constatado que a análise com o método AHP é mais rica e elaborada do que com a Média Ponderada. Porém, a grande quantidade de julgamentos paritários necessária ao estudo demandou atenção e significativo esforço cognitivo do decisor, além de maior tempo para realização das análises - aspectos que podem favorecer a preferência pelo uso da Média Ponderada em estudos similares.Associação Brasileira de Engenharia de Produção2014-11-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfvideo/mp4https://www.producaoonline.org.br/rpo/article/view/170510.14488/1676-1901.v14i4.1705Revista Produção Online; Vol. 14 No. 4 (2014); 1433-1451Revista Produção Online; v. 14 n. 4 (2014); 1433-14511676-1901reponame:Revista Produção Onlineinstname:Associação Brasileira de Engenharia de Produção (ABEPRO)instacron:ABEPROporhttps://www.producaoonline.org.br/rpo/article/view/1705/1226https://www.producaoonline.org.br/rpo/article/view/1705/1225Copyright (c) 2014 Revista Produção Onlineinfo:eu-repo/semantics/openAccessVelasco, Mileine Henriques EliasFreitas, André Luís Policani2015-11-11T17:25:32Zoai:ojs.emnuvens.com.br:article/1705Revistahttp://producaoonline.org.br/rpoPUBhttps://www.producaoonline.org.br/rpo/oai||producaoonline@gmail.com1676-19011676-1901opendoar:2015-11-11T17:25:32Revista Produção Online - Associação Brasileira de Engenharia de Produção (ABEPRO)false
