Resumo em inglês: We consider the problem of modeling the demand using exponential smoothing forecasts methods and to evaluate and control it using combined Shewhart-CUSUM control charts, with control limits calculated by simulation for this specific application. This control chart acts as an alarm for the need of re-estimation of the exponential smoothing model and its components.
