Abstract
This paper investigates the reliability of coordinate sensor systems used for process fault diagnosis in multistage manufacturing processes. When considering catastrophic sensor failure, the reliability of a coordinate sensor system is defined based on its diagnosability performance. A mathematical tool called matroid theory is applied to study the reliability of the coordinate sensor system; properties of the minimal paths and minimal cuts are derived; efficient methods are developed to evaluate the exact system reliability for two special types of systems; and an efficient algorithm to evaluate the min-max lower bound of system reliability is provided that does not require assuming that all minimal paths must be known in advance. The proposed models and the developed methods are illustrated and applied in two case studies for fault diagnosis of a multistage panel assembly process.
