Item classification strategies are explored using historical usage, cost, and engine models, combining ABC/XYZ analyses with machine learning for demand forecasting. An action research methodology is used with ARIMA, SVM, linear regression, and gradient boosting, evaluated via ME, RMSE, MAE, and MAPE on IFS procurement data, supported by interviews with key personnel. Results indicate ARIMA delivers the strongest forecasting performance for the aviation sector.","UTILIZING MACHINE LEARNING TO ENHANCE OPTIMAL INVENTORY MANAGEMENT-CASE: AVIATION INDUSTRY SPART PARTS  \nLappeenranta-Lahti University of Technology LUT  \nMaster’s Program in Computational Engineering, Master’s Thesis 2024  \nNghia Nguyen  \nExaminers: Professor Tapio Helin  \nAssistant Professor Jyrki Savolainen  \nABSTRACT  \nLappeenranta-Lahti University of Technology LUT School of Engineering Science  \nComputational Engineering  \nNghia Nguyen  \nUtilizing Machine Learning to Enhance Optimal Inventory Management - Case: Aviation Industry Spart Parts  \nMaster’s thesis  \n2024  \n59 pages, 19 figures, 5 tables, 6 appendices  \nExaminers: Professor Tapio Helin and Assistant Professor Jyrki Savolainen  \nKeywords: Inventory management, ERP system, ABC analysis, XYZ analysis, material management, demand forecasting, time series forecasting  \nThis thesis addresses inventory management challenges faced by global aerospace platforms. The special focus is given to a case company, GA Telesis which is a full-service aircraft maintenance and component services provider. Strategies for optimizing inventory levels are explored, including classifying items based on historical usage, cost and assembled engine models to identify critical items and utilizing ABC/XYZ analyses alongside machine learning for inventory management. The quantitative study methodology employs an action research approach with machine learning models of Autoregressive Integrated Moving Average (ARIMA), Support Vector Machines (SVM), Linear Regression (LR), Gradient Boosting (GB) and statistical techniques, including Mean Error (ME), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE) to predict future demand based on numerical data sourced from the IFS system’s procurement records of the case company. Additionally, interviews with key personnel provide insights into real-world challenges faced by the company, allowing the study to propose solutions specifically tailored to address these issues. The key finding of this study is that the ARIMA model demonstrated superior performance in demand forecasting, corroborating with existing literature and validating its effectiveness in the aviation sector.  \nACKNOWLEDGEMENTS  \nThe journey of crafting this thesis has been an invaluable opportunity to deepen my expertise in the logistics domain, particularly within the aviation market. I feel excitement and relief as my time at LUT University draws closer. These past two years have been challenging yet incredibly rewarding, filled with cherished memories and invaluable experiences. The friendships made during these years will certainly last.  \nI would like to take this opportunity to express my gratitude to those who helped me conduct research and write this thesis.
