- ÍtemAnalisis De Series de Tiempo Para La Estimacion Del Consumo Combustible En Aeronaves ATR42 Para Aerolınea Colombiana(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Rativa Saenz, Edwin Alexander; Moreno López, Edna CarolinaFuel management for airlines is a complex task, since they are immersed in it different variables involved that hinder its management and likewise the acquisition in terms of amounts and money can become a problem. This article performs a series analysis of historical fuel consumption data for the ATR42 aircraft, which describes and predicts fuel consumption, making it a useful new tool for solve this problem. Data consists of 730 days of fuel consumption records Jet A1 (in kilograms) and flight time (in hours). Using the ARIMA, SARIMA and SARIMAX, different solutions are proposed to explain the behavior of this variable in time. As acceptance factors, the RMSE (Root Mean Square Error) and MAPE (Mean Mean Absolute Percentage Error) and the application description is given to the data. This analysis can be used as a starting point to know the cost of fuel for the company in terms of optimization, as well as avoiding possible theft or loss of fuel, since the model can be adjusted to different variables that can describe its behavior.
