Nowadays, the organization resources management should be more accurate to avoid delay risks and penalties. One start point for planning are historical data, which form the base for forecasting the future demand. This demand forecast is used to plan resources acquisition and resources management. Frequently, the management systems of the organization do not allow detailed historical record of activities, which causes insufficient data to forecast demand and other important aspects. In this paper, data of a petroleum private enterprise are treated. The purpose of this work is to know all the feasible demand scenarios that may occur through a mathematical model based in a Poisson distribution from a scorecard. The objective of the model is to forecast demand of two types of services offered by the enterprise. Finally, a simulation model is used to validate this mathematical model.
