Errors in the bogie assembly process are among the most common human errors in the manufacturing industry. These errors can lead to workplace accidents, quality defects, and work delays. Workplace accidents are one of the most obvious types of errors and can be easily identified. However, minor errors can significantly reduce operational performance and increase production time, costs, rework, and damage rates. Calculating the significance of potential hazards and providing information for use in risk mitigation processes to minimize the impact of these hazards is known as risk management. Failure Mode and Effect Analysis (FMEA) and Analytical Hierarchy Process (AHP) are methods that can be used to assess potential failures in the process based on the probability of occurrence and their risk levels. FMEA aims to identify and assess risks based on the Risk Priority Number (RPN) for potential failures in the bogie assembly process. AHP is used to prioritize the best solutions or risk mitigation measures to address potential failures in the bogie assembly process. Based on the FMEA calculations, potential failures with the highest RPN values are identified in the crane failure to lift the frame, springs falling during lifting, and pipes breaking/bending. After performing AHP calculations, these potential failures with the highest RPN values can be mitigated through standardization, maintenance, and process control. By knowing the potential failures in the assembly process along with their RPN values, solutions and risk mitigation can be implemented based on a priority scale so that inefficiencies can be minimized.
