In production systems, demand fluctuations can lead to reduced resource productivity, increased inventory levels, higher operating costs, and lower customer service levels. Although deep learning–based models have advanced considerably in recent years, many of them still face limitations in simultaneously capturing long-term temporal dependencies and focusing on the most informative patterns within time-series data. This study proposes a BiLSTM-Attention neural network model for demand forecasting of products in a polyester film (BOPET) manufacturing company. Historical demand data were preprocessed, normalized, and structured into temporal sequences for model training. Model performance was evaluated using a walk-forward validation scheme and the MAE, RMSE, and Safe MAPE metrics, and was compared with the forecasting method currently used in the plant. The results indicate that the proposed model effectively learns nonlinear relationships, temporal dependencies, and fluctuating demand patterns, and substantially reduces forecasting error relative to the existing method. Moreover, the model’s forecasts can serve as reliable inputs for make-to-stock (MTS) production planning and other operational decisions. The findings demonstrate that the BiLSTM-Attention architecture not only improves demand forecasting accuracy but also offers practical applicability in real manufacturing environments and potential generalizability to other industries with time-series data.</p> </td> </tr> </tbody> </table> https://www.journalfwdmj.com/index.php/fwdmj/article/download/355/381
