Indirect monitoring of the failures of a flexible manufacturing system under cyclic scheduling

We are interested in flexible manufacturing systems and more particularly in their well functioning. In such a context, we opted for a deterministic and cyclic command, which optimizes several criteria such as Work in Process and workflow. In order to supervise the system functioning, we propose to survey the system output and compare it to the deterministic schedule. We will give a diagnostic principle to identify the root cause of the detected symptoms.
