In inferential statistics, forecasting is a mathematical process by which the future value of one or more variables, such as demand, is estimated. The objective of this paper was to define the classification of the main types of forecasts. In addition, to propose some of the most representative models currently used to be implemented by small and medium-sized companies, those that, based on the literature consulted, have the greatest potential to achieve a successful demand forecast. It was found that forecasts could be univariate or multivariate; however, in order to find the alternatives that would require lower cost for the enterprise by data processing, only univariate time series forecast models were recommended, as they require only historical sales data of the company. Time series forecasting models were classified into three approaches: 1) statistical or traditional, of which the Holt-Winters or triple exponential smoothing model and the autoregressive integrated moving average (Arima) model were recommended, 2) machine learning, of which the random forest model and the large short-term memory (LSTM) recurrent neural network model stood out, 3) hybrids, of which the Arima-LSTM model and the Facebook Prophet model were suggested.
