Quality is a decisive competitive edge of modern manufacturers. The objective of this thesis is to develop a knowledge-based system for handling quality-related faults in body-in-white manufacturing in the automotive industry. The developed diagnostic system includes three modules: the fault recognition module, the fault identification module and the decision module. The measured quality characteristics of an assembly represent the input to the system. The system output consists of an assessment of the process stability as well as an analysis of possible fault root causes, if any exist. While offering advantages in the early detection of geometrical deviations of the assemblies, the system also considers the posterior fault probability and the process economy in formulating a recommendation to the user. As such, the approach promises shorter reaction time, lower rework rates and, thus, a reduction of production costs.
