Analyzing Operation Management Methods for Defect Mitigation in the Mass Production of Green Car Parts

This research was conducted with the primary goal of investigating the root causes of defects in the mass production of green car parts and concurrently exploring the application of operational management principles within the domain of engineering economics.To achieve these objectives, a comprehensive methodology was employed, comprising cause and effect analysis, the Five Whys technique, and various quality control tools, such as P-charts, C-charts, X-bar charts, R-charts, process capability analysis, and acceptance sampling during sample production.The research adopted a dynamic approach, incorporating continuous monitoring, maintenance, and performance control in die casting and quality assurance during mass production.Lean production principles were also applied to ensure cost-efficiency, quality maintenance, and on-time delivery.Expert opinions, the Delphi technique, and economic outlook statistics were utilized to enhance the research.In conclusion, this study identified four critical factors essential for eliminating porosity defects in automotive die-casting mass production: gas-shrinkage solutions, mold design, material composition, and technological adjustments relating to atmospheric conditions.Operational management methods emerged as a promising approach not only in automotive die-casting but also across various industries, underscoring the continued significance of this research field.
