Abstract : The emergence of the 4th industrial revolution has democratized the use of cyber-physical systems (CPS) in the maritime sector. On board, they are characterized by various interdependent components that control critical physical operations through digital commands. An anomaly targeting one of these systems can benefit from this characteristic to easily propagate in the whole ship, and generate irreversible consequences. Firstly, we have considered the problem of dependencies at the global scale of the ship to characterize the importance of the dependencies associated with CPS. Then, an innovative 3-layer graph model (numerical, physical, and system variables) has been formulated to allow the CPS structural analysis. Various anomaly detection metrics, based on quality analysis, are integrated to initiate propagation assessment processes in a maritime CPS. This solution has been tested on two maritime CPS responsible for critical functions: propulsion and water distribution. Many perspectives emerge from this work to provide a global answer to ship anomalies propagation problems.
