- Intelligent systems for defect monitoring and diagnosis in the body shop of a automotive assembly linePublication . Costa, Júlio Cesar Guimarães; Leitão, Paulo; Barbosa, José; Alves, Gleifer VazThis study investigates data analysis techniques and the development of two analytical tools in the openZDM project for the body shop and final assembly measurement stations of a automotive industry plant. These systems were designed to generate quality information, helping the industry to achieve the Zero Defect Manufacturing (ZDM) goals. The use case section provides essential background for understanding the nuances and limitations of the case study. Next sections devised the tools to apply the Zero Defect Manufac- turing strategies, firstly the proposed rule-based monitoring framework, which enables quick adaptation of context-specific and general rules for statistical, trend, and Machine Learning based monitoring. Two micro-services serve as the diagnostic tool, evaluating the car and measurement quality while classifying defects, and generating their causes, consequences, and process implications. The tests carried out demonstrated the system’s effectiveness in handling a high-frequency data environment having a processing time 30 times faster than the required by the use case, and offering reliable outputs for proactive decision-making. The tools development was a collaborative effort within the industry partners, this concern with the operator comfort reinforces mainly the adaptation to the existing industrial process.
