Abstract
This study compares the performance of three fuzzy membership functions—Gaussmf, Gbellmf, and Trimf—in forecasting sales of basic commodities. The evaluation was conducted by measuring the Root Mean Squared Error (RMSE) and Mean Absolute Percentage Error (MAPE) on both training and testing data across various window sizes. The results indicate that the Trimf membership function provided the best performance. At a window size of 4, Trimf achieved a testing RMSE of 1.77 and a MAPE of 8.23%, outperforming Gaussmf (RMSE 2.82, MAPE 12.57%) and Gbellmf (RMSE 4.64, MAPE 17.54%). Conversely, Gaussmf and Gbellmf exhibited suboptimal performance on the testing data, particularly with larger window sizes. These findings highlight the importance of selecting the appropriate fuzzy membership function to enhance prediction accuracy. Future research could explore combinations of membership functions or other parameters to further improve forecasting performance.
