Abstract: In this article, the feasibility of using a model of estimating overall productivity in the production of aluminium formworks in a factory located in the City of Rio de Janeiro, Brazil, for the building of popular housing 'my home, my life' program developed by the Brazilian Government is evaluated. It stands out, that the concept of overall productivity, considers the productive and unproductive times, when production is stopped for some reason. The proposed model is composed of the process productivity and idleness functions. Process productivity involves all production activities of the products studied in this article. The idleness function includes all events that cause production to stop at the factory. The data collected during the production were processed via Monte Carlo simulation, using Palisade Corporation's @Risk 7.6.1 software. The results revealed that the proposed model was successful, indicating that it can be used in industry.

Keywords: overall productivity; aluminium formworks; process productivity; unproductive times; idleness; productivity model; productivity estimating; manufacturing productivity; Monte Carlo simulation.
