Abstract in Portuguese
Neste trabalho foi explorada a aplicação de redes neurais recorrentes simples, também conhecidas como Redes de Elman, na previsão de três séries temporais mensais do varejo de bens e serviços no Brasil. As variáveis destas séries estão relacionadas com a demanda de produtos farmacêuticos, adubos, e tráfego aéreo. As previsões com Redes de Elman foram comparadas com as realizadas por modelos lineares sazonais obtidos através da metodologia de Box-Jenkins.

Abstract in English
In this work we explored the application of simple recurrent neural networks, also known as Elman networks, in the prediction of three series of retail goods and services in Brazil. The series are formed by variables related to the monthly demand for pharmaceuticals, fertilizers and domestic air traffic. The forecast with Elman networks were compared with those performed by seasonal linear models obtained by Box-Jenkins methodology.
