In today’s dynamic technological environment, innovation plays a crucial role – especially for manufacturing enterprises that constantly strive to improve the quality of their products. This article examines the quality-management issue in a company producing carrims. It was identified that real-time quality control can sometimes be unreliable due to controller fatigue, leading to erroneous data interpretation or delayed responses to deviationsin the production process. The study aimed to investigate the possibility of eliminating or significantly reducing these errors by employing a tool that is based on artificial intelligence. The article covers the preparation of training data, the training of classifiers, and the evaluation of their effectiveness in analyzing control charts in real time. The adopted hypothesis assumes that machine-learning classifiers can be effective methods of support for quality controllers. The research began with collecting measurement data from the machine and dividing it into training and test sets. The obtained results were evaluated using standard quality measures for machine-learning models. The results showed that the use of artificial intelligence can bring significant benefits in improving quality supervision in the production process of car rims.  \nKeywords: Machine Learning, Artificial Intelligence, AI, Statistical Process Control, SPC, Quality Control, Classifiers, Quality Metrics, Python Programming, Car Wheel, Quality Issues  \nMathematics Subject Classification: 68T10  \nJEL Classification: C44  \nSubmitted: June 5, 2024  \nRevised: October 28, 2024  \n© 2024 Authors.

INTRODUCTION  \nThe origins of Shewhart control charts can be traced back to the 1920s, when they were first developed for quality control. These represent a statistical tool that monitors process stability by tracking sequence samples and identifying patterns that deviate from expected norms. By distinguishing between common-cause and special-cause variations, this method enables the early detection of shifts in production, thus ensuring consistent quality control over time. Shewhart control charts have been employed for qualitative analysis, becoming a key tool for collecting data during production and later analyzing it (Shewhart, 1926) .  \nIt needs to be stressed that Shewhart control charts remain in use even today; however, their roles have evolved with modern digital tools. This shift has introduced several important considerations regarding the role of AI in quality control. It remains uncertain whether AI-based systems can fully replace human operators or if they will function more effectively as supplementary tools. The potential of AI to improve the accuracy and precision of measurements in rim production is significant; however, challenges and limitations come with its implementation. The effectiveness of different machine-learning algorithms in identifying and eliminating measurement errors must also be evaluated, along with the necessary data for adequately training AI models.
