Abstract

A model to forecast the request of documents was proprosed and tested. The model was tested using the data from the Selective Dissemination of Information and Document Delivery services of the Nuclear Information Center (CIN) of the National Commission of Nuclear Energy (CNEN). The variables which were used to forecast the requests were identified and using the integration of the two systems and regression analysis techniques it was forecasted the documents of the so-called "virtual file". The results obtained have shown the viability of the application of the model.
