ResumoA alocação de recursos é um dos problemas clássicos abordados pela Pesquisa Operacional. A inserção de modelos de Análise de Envoltória de Dados (DEA) nesse contexto traz novas possibilidades de estudo, em especial quando combinada com o uso de algoritmos de programação inteira. Este artigo apresenta um algoritmo para distribuição de recursos discretos usando modelos DEA de forma seqüencial. O método proposto é aplicado no estudo de caso da alocação de vagas docentes na Universidade Federal Fluminense. Os resultados são comparados com aqueles obtidos pela comissão encarregada da distribuição das vagas.Palavras-chave: DEA; alocação de recursos; algoritmo seqüencial.
AbstractThe resource allocation is one of the main problems in Operational Research. The use of Data Envelopment Analysis (DEA) in this field is a new feature with a great potential, mainly when combined with integer programming problems. This paper presents an algorithm to allocate integer resources using a step-by-step DEA algorithm. We applied the proposed approach to a real case study, which consists in allocating teacher positions in some departments of Universidade Federal Fluminense. We compare the results with those obtained by the official commission.
The aim of this paper is to show the possibilities of integration between the teaching of Differential Calculus and Operational Research. The integration is obtained with some small changes in the way that calculus is traditionally presented and some major changes in Operational Research classes. We show that, with the above-mentioned changes, Operational Research can play an important role in the transition between the first half and the last part of the Production Engineering courses.

Sporting activities apply various multi-criteria (and multi-decision maker) methods in their championship regulations. In the majority of cases, the organizers are not aware that they are using them and indeed often apply them incorrectly. Variations of the Borda voting and lexicographic methods are among those most widely used. In the case of the Formula 1 World Championship, a variation of the Borda method is employed. This article shows that some of the problems that occurred during recent seasons are a result of the use of this method with consequent aggravation of the inherent distortions. Furthermore, the use of the Condorcet method is suggested as an alternative. Its limitations are shown, as well as how to overcome them by employing the Copeland method. Lastly, an analysis of the results of the 2002 championship is conducted
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
