Application of Matroid Theory for Diagnosability Study of Coordinate Sensing Systems in Discrete-Part Manufacturing Processes

Summary: [This abstract is based on the author's abstract.]Coordinate sensing systems are used in manufacturing processes to monitor product quality and identify process faults. However, for complex manufacturing processes or those with multiple stages, not all process faults can be identified by a feasible sensing system. In this case, a diagnosability study is important for evaluation and application of coordinate sensing systems. The diagnosability study conducted here is based on the matroid theory that improves understanding of existing results on diagnosability. The developed theory and algorithms, which are demonstrated using a panel assembly process, can be applied to a wide range of diagnosis problems.
